Will this interfere with my trunk seal or undercarriage at speed?

The Greva profile is designed to sit flush with factory bumper geometry, minimizing interference. Verify clearance by test-fitting the outer pieces first before final torquing — this three-piece design lets you adjust each panel independently to ensure proper spacing on your specific vehicle.

Should I use adhesive or drill through the bumper to mount this?

The three-piece design is engineered for bolt-on mounting through the OEM bumper mounting points. Drilling optional depending on your desired rigidity — bolts alone provide solid hold, but drilling additional anchor points is common for track use or high-speed stability. Verify your bumper hole locations before committing to any drilling.

Does this need paint or clear coat?

Real carbon fiber benefits from UV-protective clear coat to preserve the weave finish and prevent oxidation. Sand the surface lightly and apply your chosen clear coat — factory carbon does not include pre-applied protection. This step ensures long-term color retention and gloss.
