Does this wing work with the factory trunk lid, or will there be clearance issues?

The Gran Veloce GT profile is designed for standard rear-end configurations. Verify clearance between the wing's base and your trunk opening before final installation — some aftermarket spoilers sit higher than OEM equivalents. Measure your trunk lid height and compare it to the wing's mounting footprint.

What mounting hole pattern does this use?

This wing is engineered for factory mounting locations. Confirm your vehicle's rear panel hole spacing before installation. If you're modifying or drilling custom holes, reference your OEM service manual for drilling patterns and fastener specifications.

Will the wing stay stable at highway speeds?

FRP's light weight combined with proper fastening ensures stability in normal driving conditions. Ensure all fasteners are torqued to specification — refer to your vehicle's service manual for correct torque values. Over-tightening can crack the plastic; under-tightening reduces aerodynamic security.
