Will this lip scrape on speed bumps or driveways?

The GMX profile extends lower than stock, so clearance depends on your suspension setup and driving habits. Measure the height at your current ride level and compare it to the panel's extension before purchase. Use ramps or gentle angles on steep driveways to avoid contact damage.

Is the carbon fiber flexible or rigid?

Real carbon fiber is rigid by design. It will not flex during normal driving or wind gusts. The hard panel construction protects against minor impacts better than plastic, but sudden contact with obstacles (curbs, debris) can cause cracks — treat it like any carbon component and inspect regularly.

Do I need to do anything before installation?

The panel comes finished with clear coat. Clean your OEM lip and the mounting area, then install per your vehicle's service manual for fastener placement and torque specs. If you plan to refinish or modify the fit, sand the clear coat lightly and prep the surface before applying your chosen finish.
