Rear Wing Mount Overview
The RM Engineering Adjustable Rear Wing Mounts are sold as a pair of hollow 6061-T6 aluminum wing stands for compatible Ridgeline Motorsport rear wings. Five configurations are available across the GT4 MK2, Ring Spec and M235iR / M240iR wing platforms.
These mounts are sold separately from the rear wing. Select the compatible wing family first, then choose the preferred mounting position or height.

Important: Confirm the exact Ridgeline Motorsport rear wing before ordering. Similar-looking wings may use different airfoil curvature, mounting interfaces and hardware spacing. Fitment with third-party or unidentified rear wings is not confirmed.
Motorsport Mount Design
The taller configurations reference the elevated wing positioning used on BMW F82 and G82 M4 GT4 race cars. Raising the wing may place it in cleaner airflow, although actual aerodynamic performance depends on the wing profile, angle and complete vehicle setup.
Each mount was developed through original CAD design and 3D-printed prototyping around the curvature and mounting interface of its compatible Ridgeline Motorsport wing. Hollow 6061-T6 aluminum construction balances reduced weight with strength and rigidity.

Installation Requirements
Professional installation is recommended. Test-fit both mounts and confirm the rear-wing profile, mounting-hole alignment and desired angle before securing the assembly.
Verify that the vehicle-side mounting surface is properly reinforced and follow the appropriate torque requirements for the installation hardware. Inspect the mounts, rear wing and hardware regularly, particularly after track use, high-speed driving or an impact.
