Hi all,

Done some searching but not found what I was looking for.

So first simple question is what pressures are people running the Kuhmo tyres at for road and track and secondly what geo settings are people using for fast road/track use?

Going to corner weight and setup the car so would be good to start from some other people experience rather than just starting from scratch! Also what shock settings are people running?

Many thanks!

I'll be setting the car as per ther 720 top gear car.

Here is the spec:

The GTR 720 was set up as standard and the settings below are what we now recommend to run with the Kumho tyres from our recent experience on the track.

Ride height was standard. You can see from the photos that the wheels are still in the centre of the wheel arches.
Front negative camber was increased from 1.5 to 2.0 degrees
Rear negative camber was increased from 0.5 to 1.2 degrees.
Rear toe increased from 1mm to 2mm overall
Tyre pressures were front 16psi rear 21psi hot
Dampers were all set at 40 clicks (Intrax)
Road springs were 25% stiffer which are an optional extra at £240 per set.
Tyres were the Kumho Ecsta V70A medium compound all round that have been on our price lists and a standard option in addition to the Goodyears for the last six months.
Transaxle was a standard Porsche G50-03

Great thanks for that, I've already got the new spring set on the car, but having had a quick check there is less than 0.5 camber from or rear which is making it tramline on road badly so will dial in the new settings and see how thing feel.

Will keep you all updated on progress.
