Exterior & Aero

View in catalog →

Aero parts work as a system — a rear spoiler without a front splitter creates imbalance. Functional aero (splitters, diffusers, wings) reduces lift at speed; cosmetic aero (replica wings, hood scoops) is purely visual. Ride height matters: rear diffusers are most effective on lowered cars.

Rear Diffusers

Work with splitters to reduce lift at the rear axle. Most effective on lowered cars; less impactful at stock ride height.
