Ridgeline Motorsport GT4+ Aero Kit

Engineered for Maximum Performance. Inspired by BMW Motorsport. Proven on Track.

The Ridgeline Motorsport GT4+ Kit is our ultimate aero package for the BMW F8X platform—developed using the aesthetic foundation of the OEM M4 GT4 and evolved beyond GT4 rule-book limitations. By redesigning every component around real-world data, we’ve created a package that produces significantly increased downforce.

Designed to comply with GTA Street Class and GridLife Street Mod regulations, the GT4+ Kit brings professional-level aero to the enthusiast and competitive driver alike.

Proven Track Performance

The whole Kit is designed to optimize performance for vehicles with bolt-on molds only. The test results are based on Road Going F8Xs with no weight reduction with 275/35/R18 200TW Street Tires Only. F-Chassis Testing Results to Date:
