My ET Streets have hooked best at the track when around 20lbs HOT (for me that has been 17lbs cold)

try 19 and adjust from there in 1 psi increments. If it hooks, leave it alone...if it doesn't, lower psi by 1 and try again. My buddy in his CTSv runs 16 psi.

All of the previous posting pressures are track pressures. On the street I would run them about 32 to 35 cold, the sidewall likes more air on the street.

Great advice for the street. I was running 25-28 hot and posting better G-tech Pro 0-60 times than 20 hot... on a closed street. Never tried the 32-35? got me wondering now |
