This is done to induce a slight bit of wheel spin at the launch in an effort to keep the driveline from absorbing all of the 5K clutch drop. It also takes out some of the friction, thus increasing, er actually lowering, the times.Originally posted by LIL SS
Now 1 question for all the WRX people.. Why do you raise your tire pressure to 40+psi for a street race or at the track for that matter? Is it to create less drag in the run? I understand you don't really need to lower you psi from the 32 as you are not traction limited like I am.. Just trying to understand the raising of the tire pressure..
