The high speeds attained by the V8 6.1 necessitate aerodynamic efficiency. To reduce lift on the front axle and to give the coupe even more prestige, designers and aerodynamics engineers developed a front spoiler which attached to the stock bumper mounts. Lift on the rear axle is minimized by the Startech diffuser inserts that rest upon the stock rear bumper, a roof spoiler and the rear spoiler, which deploys together with the stock rear spoiler.
