Duals, and Gears...
plus any little bolt-ons you can work in,
but duals and gears are the heavy-hitters
at this level. The gears give the extra acceleration
you want, and work best on modded cars, and I
like 3.73's or higher on 5 speeds and 4.10's (+) on auto.
Get 2.25" duals for NA combos, and use 2.5" duals
on SC'ed setups.
I need to sticky my modding guide up in here for y'all
