I plan on just for fun running the car 2 or 3 times down the local track. And I am wondering with such low profile tires and same size at all 4 corners what PSI would be good. I normally drive around 31PSI on all 4.
Not too mention 6pseed and stock gears. Car is not intended for 1/4 mile but just for a test.

Should I let the air out in back and pump up front or leave them alone and just hit it because the traction will suck anyway I do it?

Too little PSI then I am on the rims, not much to play with.

thanks.

Start at 45 on the front for minimum rolling resistance track only. With 28 on the rear do a small burn out and look at the rubber patch. If it is darker in the middle lower your pressure. If it is darker on the outside raise your pressure. When you find the best footprint run your tire there all of the time and run your fronts 2lbs higher than that for the street. Radials will get the best traction with the pressure set to the ideal pressure to keep the tire flat on the road. To high or low will greatly affect your available traction and tire wear.
