LSD is a logical choice for competition - there are few options available commercially - Quaife or a couple of plate diffs - I work in the motorsport transmission world and we would not recommend plate type diffs for road use because of wear. - before any one asks we do not do anything suitable...

Cue, you are quite right, the golden rule is to do only one mod at a time, but even that is not ideal as often the first mod, in whichever order you choose, gives the best results! As the logistics of getting the car to Ben were incovenient to say the least, I wanted to minimse the number of...

Asim - hard to say - check with Ben - will be very nterested in what he has to say and how yuo find the overall package. My view is that it is a very well balanced approach - just as the car should have been in the first place Regards

7MAT - have done

Interestingly I bought the pads from Competition Braking Products (racepads.co.uk) whose registered name is Bremsen Technik (UK) Ltd. Not only do they have a very informative website, but they seemed quite happy about my reasoning for the RS15, and said that they have supplied them before in...

My car is now back from Ben, who fitted cams, modifed inlet and a re-map. His only concern was that as the car has only done 4,000 miles, all on the ex-factory full synhthetic oil, that the rings may still not be fully bedded in - wants me to use ordinary mineral for a while - and so installed a...

Alex is a fellow hill climber with a rear engined 5 turbo - brave stuff as it is an all or nothing turbo. I live in the area if you want to pm.

Simon where are you based - i presume that you will be visiting Alex Clarke at Carlton garage.

I have just bought Pagid RS15 as having the best coefficient of friction at low temepratures that I coud find - will be fitting shortly, (once the car returns from Angleworks) - again not reg 90 - but as others have said highly unlikely to be an issue. They are ceramic based, should produce a...

Very interesting article in June's Performance Tuner about a 197 on KW Variant 2 Coil-overs; even if that is not the route to go, it gives an idea of waht to expect from the R27 suspensi9n package. Still vdoes not resolve the wieght problem though

Max well spotted - there are some which make more than 100% - the MkV GTi being one of the better examples. Because the rototest system is bolted direct othe hubs the tyre to rollers losses (inlcuding hysterisis energy that goes into heating the tyres) are eliminated. depending on the gear...

Sorry chaps it is not dodgy or girlie, but closer to home www.rri.se click on performance graphs

Ollie is not far out - mortgage borrowing is the cheapest commercial deal around (especially interest only - although long-term it is not the best answer, unless you are brave enough to keep the portfolio growing in the hope that the total gain clears all the borrowingon one property) - so...

Interestingly the Private Equity company that has a stake in the company that I work for has major stake in TMD - I can not recall exactly, but think that Pagid were an addition to the group after their initial investment. In today's Autocar there is a two page advert, explaining the TMD group...

I have read in various places that the DC5 is not as good as the DC2 - seems like a combination of extra weight (1,170 kg) and clumsier handling. As per other posts I got very enthused over the new JDM CTR, but at 1,270 kg and 770 mm longer than the Trophy it is starting to get big - but still...

Re Exhausts - I think that the Miltek system has two rear boxes - not the way to save weight, bearing in mind that the power gain is probably negligible. At the Autosport show they told me that they had not dynoed it.

Steve, Thanks very much. Unfortunately the Honda Japan website admits that the the new JDM CTR is 1,270 kg- shame!!

Steve, Out of interest could you run your predictions for the Clio 197 - let's say 185 bhp and 1,270 kg. Also JDM CTR; 220 bhp (225 PS) and again 1,270 kg. Thanks

I have decided to break the mould and go for an alternative Pagid pad - the RS15, which has a much higher coefficient of friction from cold to hot than the RS4-2 and is neither as aggressive or ;'dirty' as the PF97. They recommend that I clean up the dics with emery so as to remove any...

Steve, there was a plan in the States to fit a Radical type lightweight V-8 into the Atom- at about 300 plus bhp, but with the benefit of preserving the balance. Not sure what is happening now.

Agreed re grip , I use Kumho V70A soft (treadwear index 50) which are excellent - only track tyre in 205/45x16. They are worth at least 1.5/2.0 secs, wet or dry out of 50.

Sorry to raise my hill climb experience again, but in general the Caterhams are quicker than the Elise - of course if is always difficult to compare the relative states of tune/ chassis development. There was a Caterham last year with a Hyabusa engine that was well into single searer territory -...

Dream cars would involve selling my every day car as well - then RS4 or Cayman. As an aside am waiting to see if Audi do a 170 bhp plus diesel - that with DSG could be quite interesting, particularly as the Mk II can be made to handle respectably - and would run in the up to 1,400 cc class and...

Cue - the Clio splitter is not really a splitter as it does not stick out forwards - it possibly reduces the amount of air going under the car, which might reduce drag - a genuine splitter would also help to direct air around the sides of the car instead of over, which should reduce lift (and as...

Phil - most interesting and contrary to what I was saying!! Promise you that there is high pressure at the screen base! The stagnation explanation is correct, my fault - but there are still points at which there is virtually zero flow. There are also some very good articles in an Australian...

Some after market anti roll bars are adjustable, need an installation with drop links with alternative picjk up points on the bar, so changing the leverage. Trophy uprates the anti roll effect at the rear by limiting the droop on the rear shockers. the comments sound a bit overkill/poser...

Cue - sorry - just don't know Hoolio - great but unbelievably noisy. This all could explain why some cars duct from the side of the bottom centre rad duct, oh and why some cars with two small intercoolers just don't perform.

I did something similar many years ago on a MG Metro (1,400 Longman) and it developed a missfire over about 70 mph. The aero folk at work reckoned that it was probably due to erratic pressure fluctuations, or even stagnation (pressure going negative) which explains why most cars pick up...

To do it properly, it needs to be sealed onto the airbox - I have enlarged mine to 75 mm, which required modifying the airbox by blending in a 75 mm aluminium connecting pipe. I am suspicious of connecting this to the foglamp aperture, as often this is a stagnation point, so left the inlet in...

I have seen Clarki posting before that it is not worth modifying, just buy a faster car. He is right to the extent that you can never make a good car out of a bad one; that if you spend too much you will never get your money back and can easily make the car less attractive to most potential...
