ORIGINAL: drag racer
if its still gonna be street legal, and have 600 whp you wont need a wheely bar, it wont pull the front tires high enough with street tires that youll need a wheely bar, unless you just want it for looks. and you dont need to strip the inside for a drag car, unless you are trying to compete in higher, more restrictive classes.
For every 100lbs you take off the car you can gain 1/10 of a second in the 1/4 mile.
