Will this interfere with the factory undertray or bumper support?

Before installation, verify clearance against your OEM bumper assembly and any undertray components. The lip is designed to sit below the factory bumper line, but your specific vehicle's mounting points should be confirmed during fitment to ensure no contact or interference.

Should I use adhesive or drill mounting holes?

Both methods work depending on your preference and intended use. Adhesive offers clean aesthetics and reversibility; drilling provides permanent security for track use. Surface prep is critical either way—sand and clean the mounting area thoroughly before committing to your chosen method.

How do I prep the FRP before painting?

Sand the entire surface with appropriate grit to promote paint adhesion, then clean away all dust. The raw FRP condition means the panel is already prepared for your topcoat application—follow your paint system's recommendations for primer and final finish.
