need help with traction

i have a 95 z28 m6 with a holly tb, cai, sfcs, boxed lcas, hooker cat back, grantelli maf, 3.73s, and 315s. i just recently got the 315s in hopes of clearing up my traction issues for the most part, they definately helped but i need more traction. any ideas?

What kind of 315's?

315's are no good for drag racing. They have no side wall. You need something with a bigger sidewall. After you get the right tire, the best mod you can do is QA1 adjustable front suspension. That alone lowered my 60ft times by 4 tenths. Huge difference.
