Will this spoiler interfere with trunk seal or lid clearance?

The STI profile is designed to sit cleanly on the trunk without binding or compromising the lid's seal. Verify fitment by checking alignment with your trunk edge before final fastening to ensure proper clearance.

Should I adhesive-bond or drill through the trunk panel to install this?

Both methods work depending on your preference and reversibility needs. Adhesive mounting preserves the trunk panel; drilling offers permanent security. Prep and degrease the mounting surface thoroughly regardless of method for lasting adhesion or fastener hold.

How does FRP perform at highway speeds compared to heavier trunk spoilers?

FRP's lightweight design minimizes drag and vibration at speed while its rigid molded construction resists flex under aerodynamic load. Sand and prep the surface before finishing to maintain bond integrity and appearance over time.
