What mounting holes does this use, and will it interfere with my OEM trunk lid?

The MR design uses standard wing mounting locations. Before drilling, measure your trunk lid opening and test-fit the assembly in the raised position to confirm clearance. Your vehicle's service manual shows the OEM hole pattern and safe drilling depth.

Does this require fasteners, or are they included?

Hardware is not included with the wing assembly. Fastener size and type depend on your specific trunk construction and mounting preference. Verify bolt diameter and length against your trunk reinforcement before purchase.

Will this wing stay stable at highway speeds and track use?

Carbon fiber's rigidity and low weight make it naturally resistant to flex and vibration. The three-piece design distributes load across multiple mounting points. Proper fastener torque (reference your service manual) and full contact between wing and trunk surface ensure stability in all conditions.
