How much faster will my top speed be when I change to a body kit? I know it will be faster because of reduced drag I just want to know how much.

 

it will be 100% the same. the car is limited to a top speed of 127 mph, and if that govenor wasn't there, the top speed would be about 135 mph when the car gears out in 5th.

body kits aren't really for aerodynamics, they are more for looks.
