RA-1 Tire Pressure

So it had been a year since I had been to the track and I couldn't remember my tire pressures I usually run. Tires are 255 RA-1's. Alignment is -3.7 degrees of camber up front and a touch of toe out. -2.0 degrees camber rear, zero toe.

I started around 42psi. The car seemed kinda loose so I lowered to 38 psi, it felt better. Then I dropped it to around 36 psi, again it felt a little more planted.

What pressures are you boys running?

-3.7 FTW! I have my bolts on the KW's maxed out and the camber plates maxed out.

Turns out the front end was too low as I didn't raise it after I slammed the camber. I'll get that fixed. It looks cool with the tires tucked but not great for front traction.
