[quote=BigDog]The following is a quote lifted from Chris Shenefield on his RedShift Motorsports site:
"If you run really high pressures to get the car to rotate, you will find the car will have more of a tendency to snap oversteer. Running lower pressure as a means of getting rotation will afford less "snappiness" at the limit because the tire is softer. Furthermore, the lower pressures in back allow a slightly higher slip angle at all lateral acceleration levels; so the tire has more lateral movement throughout the entire turning sequence (from low g to high g), and that's usually what you are after. High pressures induce oversteer by actual slip of the tread (oversteer), which is a little harder to control and can catch you off guard, especially on by fast courses."

Like that guy knows what he's talking about HA.
I know when I ran GS in teh si I had the 245's up front withthe 225's in the rear and ran umm around 14psi rear to help rotation. We found that that was almost ideal, and it just couldn't keep up withthe MINI's.
