I'm completely guessing having never run AD08R myself but those pressures seem pretty low for a road setup. You're unlikely to generate more than a pound or two with road driving I guess.

I always aim for 30psi on my tyres as a starting point (hot), it's just a nice round number. You're unlikely to want to go higher than that on a performance tyre - so by starting at one end of the spectrum you can just incrementally work your way down.

Really? They are much , much better than the V105 that it replaced.

It seems about right based on looking around for the exige. I am going to add in 2psi more front and rear and compare mind

I have just been out and adjusted the pressures.
Increased front to 26 ( it was 24 ) and 28 rears.

Spotted a slight issue with the front left at 16. I guess thats where my understeer was coming from! Oooops

Still would like some ballpark figures to work with for the geo. Ill use the ones suggested above unless anyone can give me another starter for 10?

The settings that I posted seem fairly 'standard'. Track Torque in Tockwith did mine and I compared with another chap on a LoT day a few weeks ago and his settings (applied by Olly @ Phoenix) were exactly the same.

I run 24 26 on mine (AD08r).. I used to have 'Randy' spec geo on mine which had rake and almost eliminated understeer, but for the road the front was just too low. I now have a fast road setup from Back on Track - there is a smidge of understeer if I really push hard, but the rear is a bit more stable and I don't have issues every time there is a hump in the road :)

Well handled at the front and loose in the back?
