The GT4 MK2 is Ridgeline Motorsport's competition wing for E and F chassis BMW builds. More surface area, a stiffer blade, and a shape that changes the entire back of the car. It fits E90 and E92, including E90 and E92 M3, F22 and F87 M2, F30 and F31, F32 and F36, and F80 M3 and F82 M4.
The profile comes from a Dutch BMW race team's reworked version of the OEM M4 GTS wing. Ridgeline's version measures about 18 cm wider and 6 cm longer than that GTS style profile, which puts more working area in the airflow and generates more rear downforce as speeds climb.
MK2 moves to 2x2 pre-preg dry carbon in place of the wet carbon used on the original. The result is lighter, stronger, and considerably more rigid. That stiffness is the point: the blade holds its designed shape under aero load instead of flexing off angle, so the car behaves the same at the end of a session as it did at the start. Adjustable angle lets you dial it in for street, show, or track.

Optional High Mount Wing Stand Upgrade
Ridgeline's signature high mount stands are available for an additional $100. They raise the blade into cleaner air above the rear of the car and open up more angle adjustment for street, show, or track settings. The taller mounting position also gives the car a more aggressive GT4 stance.
Installation
The wing mounts to the trunk rather than to factory holes, so drilling is required. Professional installation is strongly recommended to get the wing square, mounted securely, and holding the angle you set.
Test fit and align every component before drilling or permanently mounting anything. Measure your trunk against the 140 cm blade width before you start. What the install takes depends on the car, the trunk shape, and the mounting surface.
Motorsport Product Disclaimer
Aerodynamic results vary with vehicle setup, wing angle, ride height, speed, suspension, and the bodywork around the wing.
Track use loads the wing, the stands, the trunk, and everything they bolt to. Confirming that the mounting points are reinforced and appropriate for the application is the installer's responsibility.
