The rear spoiler is designed to provide the additional downforce 400hp requires. The elevated rear spoiler has a raised center section for additional downforce while it has multiple adjustments to change the height and angle of attack for street or track driving modes.

The rear decklid incorporates a 3 ram air induction system, designed to feed the air cooled 4.0-liter engine to breath but to also stay cool under performance driving situations. Working in conjunction with the vented rear bumper it enhances the heat dissipation while the ram air system also increases air flow to the intake to increase atmospheric power.
