So I did some research on the SCCA forums and found that some people are running 42psi front and 36 psi rear. When I tried the pressures I found out that the front psi was way too high. I had major under-steer and I couldn't get any traction to save my life. I lowered the front psi to 38 and the car started handling like it should. Next race I'll try my old pressures to see if I get any more traction. Moral of the story, higher pressures tend to create lots of under steer.
