Tire pressures for track
 

Hi All,
Advice please,going to be doing a track day with my 370z roadster,the standard tire pressures are 35 psi,am still running the Bridgestones on 19 inch Rays wheels,what pressure should I run on the circuit?
Cheers.

35 hot.

:iagree:

I personally go higher, more like 40psi

I can't do that. For me temps that high make the tire harder and doesn't have as much contact patch of the pavement. Guess a lot of this has to do with what type of alignment your running also. I have to have more flex in the sidewall. For me I get better feed back and predictablility.

too much body roll with 35psi, my lap timer was showing quicker laps with the higher pressure, my car is stock remember
