Our Lotus Elise aftermarket parts include the five element rear diffuser. This diffuser offers improved downforce when compared with the standard one and has little effect on the vehicle's coefficient of drag. The 2 by 2 twill autoclaved carbon fibre material gives these Lotus Elise aftermarket parts an excellent surface finish that complements the car's design. No modifications are required. It bolts right in using stock fasteners. Our pre-preg, autoclaved, carbon fiber front spoiler is also recommended. This ultra lightweight aero aid is used with a diffuser and our other great Lotus Elise aftermarket parts.
