this is what i did when i went drags,

put tire pressure down to 20psi (at the front only, rears hard as rocks)

launched at 5500rpm, hand the hand brake up all the way, when i felt the cars rear end dip i launched and put the hand brake down.

stock itr i got my 60ft in 2.1 secs and passed the line at 14.6

buy some semi slicks with a soft sidewall, in track racing you want a STIFF sidewall, where as for drag u want a SOFT sidewall,
