I just mean nothing taken out of the car. Deadmat,seats,spare,ac,ect. As long as whatever is taken out is replaced by a similar/lighter product i.e.light wieght carpet,carbon hood/trunk,lighter suspension parts.
i dont think anyone ever thought of looking for that. most "bolt on" 2v's that go for what they can usually have seat delete, remove spare, bolt ons, k-member, coil overs, big and littles, gears, etc. a stock long block car that is fully set up can go low 12's.
