Does this wing use the factory mounting hole pattern?

Yes. The RBS spoiler is engineered to align with OEM hard points on the trunk lid. Before installation, verify that your trunk lid mounting holes are clean and that any existing adhesive or sealant is removed to ensure a flush mount.

Will the wing cause trunk lid interference when opening or closing?

The RBS design is tuned for the factory trunk geometry. Clearance is maintained during full articulation. If your trunk lid has been modified or repaired, test the fit manually before final fastening to confirm no binding occurs at full extension.

What stability can I expect at highway speeds?

FRP wings are rigid once secured and maintain form under sustained speed. Proper installation — clean mounting surface and secure fasteners torqued per your vehicle's service manual — ensures stability. An improperly mounted wing will flex; reference your service manual for correct fastener torque values to avoid this.
