I'm looking to improve my 1/4 times without doing any additional power mods. My best time was a 12.2 @ 113mph at Sacramento Race Way. 60ft was high 1.7 and I know if I get a better launch off the line, I get can get a 12.0 or better. It was only my third trip to the drag strip and I'm improving each time. Here is my current setup...

EVO IX GSR 5-speed
stock clutch
stock turbo
6,000 2 step rev-limiter
Falken Azenis 255/40/17 (tire pressure @ 27-30psi hot at the strip)
Megan street coilovers (8k/6k) adjusted stiff in front, soft in rear

What would be a desirable tire pressure for drag racing at the track? Also would like to know if there was a certain spring rate thats better suited for coilovers that see drag use.

 

ive heard 20 front and 22 rear is good for drag racing.. not sure about the suspension stuff

 

22lbs , suspension depending on the track conditions and tires tires tires make a big diffrence.
