Nissan 350Z at Donnington -Tyre pressure advice
Discussion

General consensus (and it works for me) is when the tyres get hot and so the air-pressure inside increases, you should let air out to get back to your ideal pressure.
Then before you drive home, put some more air back in.

A few points of interest from our last 350z visit to Donny.
Things about the car I discovered is that lowering tyre pressure to 34psi was alot better than the journey up on 37 psi; Toyos can go a bit soft after 25 mins of track time & better to go out in 15 mins stints; Motul RBF 600 brake fluid did the job perfectly with no brake fluid boiling; std suspension just about copes with trackdays but if I was going to do more regularly I would definetley consider adjustable coilovers. Finally brakes: I thought they were going superbly (Brembo Calipers/std discs/EBC Redstuff pads) with no brake fade & I was confidenly approching Redgate braking later & later. But when instructor CLive drove it he did say that he thought either pads/ discs or both are not up to the job as they were rather spongy & did not bite enough. The red stuffs were definetley an improvment over std pads but may not be good enough for track, only fast road use. In fact i need to post some pics as this morning I inspected the pads & there are couple of chunks 2cm holes torn off the pads as well as cracks that appear to go right up the pad!!! I think the correct terminology is they are shagg3d!!! These were put in about 6 months ago but Im wondering whether I can get any more road use out of them or not? Definetley they cannot do another track day.
