Ridgeline Motorsport GT4 V2 (Longer Version) Carbon Fiber Front Splitter for BMW F8X M3 / M4

The Ridgeline Motorsport F8X GT4 V2 Front Splitter takes inspiration from the BMW F82 M4 GT4 and E9X M3 GT4 race cars, combining aggressive motorsport aerodynamics with a cleaner and more practical mounting design.

The original F82 M4 GT4 V2 splitter features an extremely aggressive profile and requires drilling through the upper surface of the front bumper. Our GT4 V2 splitter was redesigned with a more compact profile that mounts entirely from underneath the bumper, eliminating exposed mounting hardware on the upper bumper surface.

Extending approximately 4 inches from the front bumper, the GT4 V2 provides a substantial aerodynamic surface for a more aggressive front-end appearance and increased front-end stability at speed.

Two integrated, functional carbon fiber brake cooling ducts help direct airflow toward the front brakes, supporting improved cooling during spirited driving and track use.

Competition Use Notice

The splitter’s approximately 4-inch extension was designed with commonly used Global Time Attack and GRIDLIFE Street-class aero limitations in mind.

Competition rules may change, and vehicle eligibility depends on the complete vehicle configuration rather than the splitter alone. Drivers are responsible for reviewing the latest event and class regulations before competition.
