SLP's Sport Suspension Lowering Package and Sway Bars lowers the Corvette up to 2" front and rear. This package improves the handling and reduces the frontal area of the car. This results in a reduction in the drag coefficient (the amount of force required to push the car through the air). The lower the drag coefficient, the better the fuel mileage.
SLP C6 Corvette Sway Bars are 32mm front and 29mm. The Z51 C6 Corvette factory sway bars are 31mm front and 25.6mm rear and base C6 Corvette factory sway bars are 25.5 front and 17.5mm rear bar.
