Graham, I worked on the principle that the recommended tyre pressure is 22psi on the front (25psi on the rear), so I thought that a nearly 25% increase should cover it. It seems that my guess was on the low side, I'll ask MMC to find out from Avon what the official recommendation for track-day pressures is?
I'll also ask them about camber changes PJ. But, I think we all have to remember though that despite the Top Gear programme, it is not really a track-day car.
