Car collected from Ratrace.

Right, collected the care from Rob at Ratrace and I am very pleased with the standard of his work, knowledge of all thing mechanical and specifically 7.  His approach is just really good in my opinion, wanting to get things right but not reinvent the wheel unnecessarily.  I will definitely be going back to him.

Upon collection Rob, adjusted the throttle pedal for me to be able to heel and toe on down changes and then set the rear anti-roll bar drop links with me sat in the car.

The car starts and idles very nicely.  In fact, the engine is now so smooth.  To start from cold it requires a little throttle until the engine starts to warm, at which point it is rock steady.

The fitment of correct track road ends has made a noticeable difference to the steering.  It was good before but now is sublime, reacting to the slightest touch with a new found lightness and feel.

The engine needs to be mapped and Rob has strongly recommended travelling to Emerald http://www.emeraldm3d.com/rolling-road in deepest, darkest Norfolk, to get this work done.  I just need to remind them that the air horn length (throttle trumpets) has been set at 90mm and may need a little adjustment.  I also want to a sensible rev limit set as my K Series has a standard bottom end and the Caterham Super Sport rev limit (7600 rpm) is generally viewed as too high for sustained use, without a forged bottom end.  To that end, I have been advised by both Dave Andrews t/a DVA Engines and Rob at Ratrace Motorsport that anywhere between 7,000 to 7,200 rpm should be fine; and will take Emerald’s advice on the day.

I also need new lower (front) wishbones fitted and new suspension all round.  I think that is likely to be a set of the excellent Nitron NTR1’s.  Typically Caterham are out of stock of right hand lower wishbones, with an expected delivery date of 9th February.  Rob has a set on back order for me.

Watch this space for updates!

Darn!  New lower wishbones required….

Darn! New lower wishbones required….

Phonecall from Rob at Ratrace Motorsport to say that he was wrong when he though the spherical bearings in the lower wishbones needed replacing.

Upon closer examination, he had established that the bearings were moving in the wishbone bearing carrier.   Unfortunately, it appears that when these were powder coated (July 2016) the inner faces of the carriers were cleaned up a little too efficiently resulting in the carrier becoming oversize and bearing moving around.

This will require two new lower wishbones:

Purchase: RDX (LED) flasher unit relay from Just Add Lightness

  • RDX LED Flasher Unit Relay

This is our top of the range flasher (indicator) relay and it replaces the standard relay when you upgrade to LED lights. It corrects the indicators flashing too fast without the need to use a load resistors. This relay has been tested on Caterham’s with the Just Add Lightness LED lights.

Why do I need this?

LED lighting draws much less power (load) and lasts way longer than standard incandescent lighting. Replacement of indicator bulbs with LED’s will cause the indicators to flash too fast. This happens because your new LED lights draw such little power. Installing an LED flasher relay specifically designed for LED lights is the easiest method to solve this problem.

What about load resistors?

Some people choose to fit load resistors to imitate the load of the incandescent (standard) bulbs that they have just removed. This results in more wiring, things may get hot and you are probably using more power than the standard bulb set up that you just replaced! Installing an LED flasher relay is the easiest way to solve the problem.

Whats the difference between this RDX relay and the Wipac relay?

There are many LED relays on the market and the Wipac is largely considered one of the best. However, no two Caterhams are the same and we have found that the Wipac relay is not compatible with approximately 40% of Caterhams. In these cases a more uprated relay is required and this is where the RDX steps in. The RDX has been specifically designed to handle any LED/standard bulb combination. Where other relays fail, the RDX does not. It was originally designed for Land Rovers pulling trailers with a mixture of standard and LED lights. Most LED relays can handle 30-40 Watts, the RDX can handle 140 watts! Its tough and it works perfectly in a Caterham. It has a 100% success rate.

Whats in the box?

  • 1 x RDX 4 pin LED flasher unit

 

Technical Specification

  • 12v
  • Works with any combination of both LED and standard bulbs

 

Additional Information

  • This relay has a manual adjustment for the flasher speed but this is not used on Caterham cars.
  • This relay has 4 pins and the standard Caterham has 3 pins. This is normal and the relay will still fit and work in your car.

Article: Why change to LED lights?

From the Just Add Lightness website:

Why Change to LED?

Upgrading your Caterham’s lights can provide substantial benefits such as increased visibility and safety. 

What Makes LED Lights so Much Better?

Safety –  LED’s are better for stop lamps than anything else, as they light up almost instantaneously. This gives the drivers behind more time to react to avoid an accident if a car makes a sudden stop. It might seem insignificant that a LED lights up 0.2 seconds faster than an incandescent bulb, but at 75 mph this translates to 21 feet extra braking distance for the cars behind. This can literally make the difference between life and death.

Efficiency – One important advantage an LED light bulb has over a traditional light bulb is its innate efficiency in converting electricity into visible light. A traditional light bulb only turns approximately 3% of the electricity it receives into visible light. The remaining 97% is wasted as heat energy, which does nothing to help with illumination. On the other hand, an LED light converts about 90% of the energy it receives into visible light with only 10% given off as heat waste. This means that an LED light bulb can produce substantially more illumination per watt than a comparable halogen bulb.

Long Lasting – Essentially, the filament inside a normal bulb is on fire. If there is anything impacting how it burns — if weather conditions be too hot or too cold — the traditional bulb could fail and need to be replaced. While halogen technology has advanced to the point that this filament can last between 1,000 – 2,000 hours, LED lights far exceed this lifespan. The design of the LED means it is much more stable and is less prone to failure. The result is an extremely long lifespan, typically our LED’s will last between 10,000 – 50,000 hours!

Endurance – Since an LED light eschews the traditional glass bulb format, it is considerably more damage resistant than traditional lights and can, therefore, endure more punishment from vibration, impacts, and other environmental hazards. At Just Add Lightness we only use the highest quality LED’s to ensure our products can withstand years of abuse and keep on shining.

LED lighting is relatively new compared to previously established technologies and costs more to produce. This means that LED lights are more expensive than their halogen equivalents. However, this investment pays off over time thanks to the longevity of the LED light design.

What is an LED Light Bulb?

Traditional light bulbs have followed a similar style of construction since their invention: a filament inside of an enclosed glass envelope containing some kind of gas. When the filament receives power, it burns and produces illumination. Compared to other light bulb designs, they are relatively inexpensive to produce. For this reason, vehicles are usually equipped with halogen light bulbs.

Rather than a filament burning in a gas-filled chamber, LED’s produce light when sufficient voltage is applied to the leads on the diode, resulting in illumination through a process called electroluminescence.

Are Just Add Lightness LED’s better than fitting a 360° LED bulb?

Yes! By their very description a 360° LED bulb will send light in all directions and may rely on some sort of reflection. Some estimates show that as little as 40% of the light produced is sent in the desired direction. Our bespoke LED solutions are designed specifically for the Caterham, all LED’s face in the correct direction with no reflection required ensuring that 100% of the light produced is visible to other road users.

Quality Assured

As with any product there are cheap versions and high quality versions. LED’s are no different and there are many cheap LED’s available from China. We have rigorously tested dozens of products and we have found that many are sub-standard, less efficient and unreliable. With this in mind, we ensure that all Just Add Lightness products only use the highest grade, branded LED’s and components, to ensure the highest possible satisfaction for our customers.

Our LED panels are manufactured to both ISO9001 and IPC610 Class 3 standard. IPC610 Class 3 is the highest standard possible for Printed Circuit Boards and is often associated with military and aerospace panels.  Class 3 PCB’s are defined as; products where continued high performance or performance-on-demand is critical, equipment downtime cannot be tolerated, end-use environment may be uncommonly harsh, and the equipment must function when required.

If you’re looking for a lighting solution for your vehicle that combines efficiency and improved illumination, LED lights from Just Add Lightness are a great choice.

Meteor Motorsport suspension options

Right spoke to Simon Rogers at Meteor Motorsport this morning, to discuss my options. Prior to doing so I read his excellent buyers guide which I attach below in italics.

With my budget I am realistically looking at Nitron NTR1’s with the Suplex springs or possibly Eibach or Quantum Zero One’s, again with Suplex springs or Eibach but with the Digressive shim pack for the front shock absorbers.

Both currently have a lead time of aboyt 5 weeks.

Will wait for Rob to come back to be and then have  a conversation with my lovely and very understanding wife.  Simon Rogers very helpfully reminded me that this is a safety issue… no sure that will wash!

“I will try to answer and highlight the more general information which can be applied to your car before making recommendations at the end. You may find me rambling a little and referring to specific cars half way through.

As I hope you are aware I sell a range of brands of dampers. I also sell a range of specifications – non adjustable all the way to 4 way adjustable.

In order to justify to the manufacturers and customers why I recommend one product in a price range and specification over another I have set out all similar products to make the same margin in actual £ not percentage.

So on a 1 way set of Nitron’s I make the same margin as a 1 way set of Quantum and so on through the various specifications. I hope this justifies our independence and impartial advice.

Here we go then – fixed rate, 1 way, 2 way,3 way or more:?

Justifying a set of the 4 way Ohlins TX40 or 3 way Penske for road use will be difficult, however if you want the best specification at a very reasonable cost and you really want the ultimate adjustment, quality of product and brand then they are worth every penny. Indeed I have sold a number of sets to road going owners who wanted just that ultimate performance. You will never ever need another set of dampers! In many respects I think you possibly feel the better quality of a damper on the road than you do on a track

where surfaces are far smoother and consistent. On track the clock and your confidence will always feel that performance gain. Fixed Rate Dampers

As it says really these are suspension dampers which have no adjustment for the valving of the damper. They do have ride height adjustment but nothing else. For this specification we only offer the Quantum Zero. It is available in regular linear piston and valve configuration, digressive/linear piston formats. Our specification will make sure the suspension will be set up exactly for your needs not to hard and certainly a great improvement on standard dampers. (For digressive valving and pistons please see the information below).

The Quantum Zero is fully upgradeable to either one or two way in the future if required as it would be to add digressive pistons at a later date.

Quantum Zero £1091.08 incl springs + vat
1 Way Adjustment – One adjuster that alters both Compression and Rebound settings

In the one way range we have AVO Twin Tube aluminum dampers (not gas pressurised) Nitron Street Series, Quantum One.Zero, Nitron NTR1, Nitron NTR1 Pro 46mm and Penske 7500. The most cost effective of the 1 way damper is the
Nitron Street Series @ £699.00 (Only available for certain car specifications).

AVO £684.20 + vat
Nitron NTR1 @ £1299.00 + vat
Nitron NTR1 @ £1587..50 + vat
QRS One.Zero @ £1399.00 + vat
Penske 7500 1 Way @ £1980.00+ vat (or £2320.00 + vat with clicker)

Nitron offer two great value, well specified products within this range, both recognizable by the smart hard anodised grey exterior coating. The Street Series may well be the damper for you if you are looking to upgrade your regular road use damper to something for more focused and spirited driving. These offer a wide range of adjustability, albeit having factory specified valving, which is the same both front and rear. Spring rates are also factory specified and are biased slightly towards retaining a reasonable degree of compliance on the road. The Street Series has at least 35 clicks of adjustment.

The NTR1 is probably the more familiar of the Nitron 1 way dampers which you will see on many Caterham’s. This is altogether a more focused product that benefits from being ‘made to order’ so allows input from Meteor to ensure our massive experience with Caterham suspension is fully utilised. The NTR1 has 24 clicks of adjustment.

The Nitron NTR1 Pro 46mm until recently has not been something I would have recommended for use with a lightweight car. It has not been able to flow enough oil at low speed damper movement (giving to firm a ride). Now though following work with our Autograss customers I am able to use a high flow 46mm piston in the build specification. This now means that the 46mm Pro damper performs exactly as required. With the benefits arising from greater oil capacity and strength it’s a great damper that should be considered.

The QRS is entirely manufactured and assembled in the UK save for perhaps the O rings or seals used. The quality of engineering design and indeed finish is second to none. Hard anodized just like the Nitron and available in an all black finish if required for a small additional cost.

The One.Zero has 27 “clicks” of adjustment. Very progressive and you really do feel the “clicks”. The Quantum has finer adjustment but the Nitron can be adjusted over a wider range.

Both manufacturers recommend bi annual service intervals. The main differentiator between the two dampers is the upgrade path and options. The most significant difference is the availability of the Digressive piston with Quantum. I think this makes a significant difference particularly to front end “turn in” and positive feedback through the wheel. Additionally the Quantum can be built into a 2 way damper with very little work perhaps at the time of service.

The Penske is as you would expect a fantastic product but I feel the Nitron and Quantum offer better value at there respective prices. If you want the ultimate performance it remains an valuable option.

I would have no difficulty recommending any of the above – it is dependent on the options and upgrades you may wish to make in the future.

2 Way Adjustment

We have 4 options here but only from 3 manufacturers .
QRS Two.Zero @ £2097.00 + vat
Penske 7500 @ £2337.60 + vat (sweep adjuster) and @ £2677.60 + vat. (clicker knob adjuster). Penske 8300 @ £3744.00 + vat – remote reservoir and upgradeable to 3 way 8700 specification.

Ohlins 2 way with remote reservoir @ £3390.00 + vat
Ohlins ILX 2 Way – no reservoir required @ £4010.00 + vat (Fantastic dampers with great performance and packaging. Very easily tuned or modified to adjust in more “ways”).

The Penske 8300, Ohlins and Quantum all have digressive piston options. We have just taken delivery of the first Nitron Digressive pistons for us to develop. These will be available later in the year. Penske and Ohlins included in cost and Quantum @ £250/set. I think the Quantum offers the better value for money at this level but you need to offset this with Penske and Ohlins reputation, performance and brand. The Penske 8300 however is a fantastic spec and damper now with the possibility to upgrade to 3 way. This would be my choice if funds were available. I must emphasize that the Quantum has nothing to worry about here either coming from F1 History. I guess I am saying its personal choice.

3 & 4 Way Adjustment

At this level we have the Nitron NTR3, Ohlins ILX, TTX40 and Penske. I have owned and used the Nitron NTR3 Pro for a competitive season and they were faultless. We now have new high flow pistons and valving available making this a great step into a multi way damper. Although a significant price differential my current damper of choice is the Penske 8700. There currently is a significant difference in the way the dampers perform and the way the car responds. If you are choosing a multi way damper it is likely you require the fine adjustment and performance of the Penske. It comes with a Digressive/Linear piston and is infinitely adjustable. Simply superb. I use this myself as it offers huge performance for a very very attractive cost. We have also just received the specifications for Ohlins ILX and TTX40. The ILX are an all in one damper with no remote canister and are of a very high specification. The TTX40 is a damper of a through rod design and just like the ILX have no external reservoir and are easy to install. These dampers require no remote canister and are available in 2, 3 and 4 way adjustment. The like for like cost is shown below. I would certainly recommend them if you have the budget. I have tested them on our dyno and the results and range of adjustment are at another level again. This is though reflected in the cost!

Nitron NTR 3 – £2712.50 + vat Nitron NTR 3 Pro – £3062.50.00 + vat

Penske 8700 – 3 Way – £4904.00 + vat Ohlins ILX – 3 Way – £5190.00 + vat

Springs

All of the above dampers (except the Street Series) can be supplied with linear springs or with our own twin spring progressive set up. The benefits of the progressive set up make for a far less harsh ride. I particularly like them on the rear of a 7. Do not underestimate the significant benefit that the new dampers and valving will bring to ride quality but the twin spring is a fantastic extra.

Pistons and Digressive Valving

Now just to confuse or add to the decision making process further I have developed with Quantum a valving and set up with what we call a “Digressive” piston. This affects the shape of the damper force curve/plot. It brings a further enhancement to ride and performance. Unfortunately as always there is a cost implication as the machining process for the digressive piston has to be completed on 2 different machines and has to be handled by a “man” a number of times. The linear piston is one machine – one time handling.

The digressive set up is available as an additional cost for both 1 way and 2 way QRS dampers @ £260.00 + vat For reference the 8300 and 8700 Penske’s comes with a digressive piston as standard.

General Information

Lets look at the standard dampers.

Bilstein. I have tested many and most of the various M1/M0 types etc (there are far more than the 2 specs). They perform well – the curve/plot is good except it’s all a little soft IMHO. Digressive in shape = good but just under damped. Works well on a road car with less power and momentum. Spring rates OK – front could be stiffened a little – rear is progressive and good.

My testing of these has found that although they seem not to fail to often they do not match each other very accurately. Indeed after testing one batch of 9 front dampers the range across all was in excess of 60% of the adjustment in a Quantum. Additionally it was the newest set that were the furthest apart. – hardest and softest. This not a criticism – they are simply different spec dampers intended for different work.

Any of the new dampers will make an improvement to ride and control, precision etc. So long as we get the spring rates correct they will not be harsh either.

So what to do? Well I do not yet know your budget. I will therefore make some assumptions.

You would like to see a good step up in performance – you probably drive it faster than when you first had the car so it’s not so much as the car falling away as you improving and feeling more comfortable. It’s a very very fast and stable car so you need to ensure it has the poise to make use of its power.

Option 1 – Ultimate spec.
Penske 8700 Series – 3 way adjustable – £4904.00+vat or Ohlins ILX 3 way – £5190.00+vat Nitron NTR3 Pro – £3062.50.00 + vat

Option 2 – High Spec/Performance 2 way

Penske 8300 £3744.00 + vat or
QRS 2 Way – Digressive piston £2357.00 + vat Ohlins ILX 2 way – £4010.00 + vat

Option 3 – 1 way adjustable

Difficult Choice – its up to you and your future plans. Nitron NTR1 – Linear £1299.00 + vat
QRS – 1 Way – Digressive/Linear Piston £1659.00 + vat

There are so many options without a budget it is difficult for me to make a selection. Let me have some figures and I will guide you more accurately.

The only thing I would add in the first instance is that I do offer a stiffer set up for the track guys – that’s the whole idea of speaking to me rather than a manufacturer who knows the dampers but not the car.

Lead Times

The approximate lead time for the manufacturers is stated below. Nitron 3 Weeks
Penske 3 Weeks
Ohlins 10 – 12 Weeks

Quantum 5 Weeks”

Houston we have a problem… well sort of

Rob from (the excellent) RatRace Motorsport phoned last night with an update.

The throttle bodies are fitted and that project is complete (just requires setting up on a rolling road, which will be down to me – when it is a little warmer!).

However, having stripped the rear suspension down to fit the new De Dion tube and then set the car up, he identifed that the car required new springs all round (something to do with being the old style progressive springs… I think), and that one of the adjustable spring platforms had seized (at the front I think he said).  In his experience it is apparently very dificult to free a seized platform without damaging the unit.  Closer examination had also identified damage to at least one of the rear shock absorber units. He notes that they had been hand painted; womtehing I was aware of when Seven and Classics overhauled the suspenion last summer (2017).

His ris o fthe opinion that the current suspension is original and is at the end of its servicebale life and recommends that it should be replaced.

Original Bilstein suspension are currently very expension through Caterham cars and therefore this makes upgrading the suspension to something like one of the Nitron or Quantum range, a sensible proposition.

He is going to make some enquiries and get back to me.

I mentioned Simon at Meteor Motosport and that I was aware that he offers Caterham specific valving for the Nitron NTR1 and Quantum Zero One ranges.  I think Rob was going to speak with Simon.  I may do so myself as having read Simon’s excellent buyers guide he likes to tailor spring rates etc to the specific car and how it will be used / power level / weight of the driver etc etc.

Watch this space…..

As an aside, what concerns me about this, is that my car has only ever been trusted to marque specialists with strong reputations for knowing 7’s inside and out and also excellence.  What is now apparent, is that they all without exceptions have missed things or in the case of the suspension damaged it and either not noticed or not flagged it up to me. This isn’t about proportioning blame or naming and shaming but is has been a salient lesson to me and I am pleased that I appear to have found someone who is really very good.
