i wouldnt waste my money on a VIS hood, not much weight difference from stock. try fiber image cf hood, they are much lighter and stronger, big difference from stock and VIS hoods. if you want to lose weight on your car, complete a/c system from condensor to the heater core and remove the power steering which will take out about 75lbs. having weight reduction can make a difference if you take enough weight off. having your car 200-300lbs will make a difference in times. also..putting in gsr seats will add more weight to your car..try some racing bucket seats.
