No disrespect Rob but having not used a KW coilovers set up and by using electronically controllable suspension you don't seen like the right person to be taking advise from.Let's just say that I've got nothing against KW but just don't like the way they just adapt older Koni stuff and sell it for exobitant prices. KW v1 (especially the non stainless version) just ain't worth the money (V2 is a bit better and V3 is good).
I only say that just for road use next time I would go for Bilstein since I like their B14 coilovers more than the KW V2 (and they age better than V2).
The question was for the clubsport version and that one is as good as it gets when someone wants a system that has to be used for combined track and road use.
In my 500+ bhp IS with supra conversion I went for tein since I wanted a system that offers 5 different setups for road and track use (that can be chosen with a single push on a button). Imho there is no system without dynamic adaptation that is good for both purposes but some might disagree (911 RS is a good example, some owners say it can be used day to day but few do since it's just plain harsch).
Downside with tein is that it's japanese and rebuilding it is no option. The good thing is I know at least eight high performance cars with this system build in and even the electrical part is flawless and stays this way for years.
If I would want something for just track use I would go just around the corner and order me a custom setup from Intraxx. Don't know what the most used brand in the uk is for track suspension but for the price of the clubsport I would have a complete Intraxx system and the setup adjusted by a pro and still have money left for a few rebuilds (in fact I had one in my former Donkervoort which did nice as a track car but was back breaking even when I went to get some fuell with the car a few miles of the track).
Koni are a VERY well respected suspension company in Britian.
Without tracking a car that is set up properly a good driver would not find the limits of the KW kit and see the benefits of a kit twice the price of it, ie Intrax.
