There cant be any excuses. You drive the car out to the "race track" you line up....you run...there is a winner...end of story. All this BS about tires, weight, cylinders, cubis inches etc is all semantics.
We all have control over what car we buy and how we modifiy it. Be it AWD, RWD, FWD, V8, I4, turbo, all motor, nitrous whatever. The finish line is what counts.
