By removing 20 pounds of weight you gain the equivalent of 10 hp. This is
true for heavier/slower vehicles. The number moves up exponetially with
faster/lighter cars. Removing weight from the front of the car is more
effective than removing weight from the rear. Little things might not seem much
but collectively they make a real difference. This may look like stripping the
car but you want to go fast at the track.
