Drag Racing Tech - stock suspension

i am running stock suspension on my 01 camaro ss i posted some threads about lowering my 60' and everyone said rear suspension. stock rear gears, m/t et's,4l60 tranny, 3700 stall. car has a little over 400 to the rear wheels. so what do i need to do to my suspension?,and about how much better time should i expect?

Depends on how quick you want to go. Tq arm, LCA and LCA relocation brackets universally help. A set of from and rear shocks would be one of the best parts to swap out. 60ft times will vary, I have a few friends running 1.4s on stock parts. It's really hard to answer your question other then it will improve
