[ra6t7gto]

i run my 67 gto at stock drags with f - 70 redlines,i tried a few different psi stock @ 32 psi it seemed ok, went to 45 in the rears and car had no traction broke loose going into 2nd gear,went to 40 psi and got a little more traction, last time out at e town i had rears at 30 psi and it seemed to get more traction, just my 2 cents
