well i dont want to go against what the others have said, but i go consistent 1.53-1.55 60' times on regular TNT nights with STOCK tq arm, BMR lowering springs, STOCK shocks, and i have relocation brackets and BMR lower control arms. stock springs are great for drag racing. relocation brackets are great for stock height cars too. more loading of the rear is needed. just dont need to go to the lowest setting on the bracket. i have about 100 passes of 1.59 60' or quicker on my STOCK tq arm. its fine for me launching on slicks. ove 400 passes on the tq arm overall.

squating is NOT good for drag racing. if you want weight transfer, you want the front to rise slightly. get the weight off the front. the rear should plant the tires. in fact, the rear should actually rise. yea, not the popular answer! the tires do the work, NOT the suspension. any chasis twisting is bad. transfer that energy to the tires

this is on my 328 rwhp trans am.
