First track day this Friday, more or less tire pressure?

[986chris]

i've got sumitomo htrz and found 35 psi to be good # 32/33 was too low always howling. i reset psi just before going back to que. buying pyrometer this year, any suggestions? there's nothing better than a track day!!!

motoadve, if I remember correctly, you have a 987. Why are you running such low tire pressures? I think the recommended pressures are 32 front and 37 rear.

At the track I was running 40psi , meassured hot in all 4 tires and it was working good.
