I have just swapped over to rms upper control arms and calvert 90/10 shocks to improve 60ft times. Last weekend i took the car out , the launch was a lot more aggresive, front end rises very quickly but car is loosing 60ft.
I managed to find a pic of the car on the net and it appears to be squashing the tyres a lot.
Car runs 9 way ranchos and ss springs, new 31X10.5 Hoosiers, 4.56 gears.
Car was running 1.53 60 ft's down from 1.48-1.50.
What pressures should i try, have been running 8 to 10, i'm thinking of going to at least 12 and stiffening the rear shockers up a lot.
