Suspesion set up
#3
it wont make it "quicker" but a good/properly setup for the drag strip suspension will help your car launch, come up & come down properly, hook better, & be more stable throughout the pass, which yes, can cut off sometimes as much as 3 or 4 tenths depending on your overall setup & power. "balancing out" i think would mean balancing or setting up your suspension for drag racing. not sure what else you would "balance out".
