Will this interfere with my bumper or splash guards at speed?

No. This lip is engineered to sit at the factory bumper edge and works with OEM splash guard geometry. Verify your front bumper is in stock condition and mounting points are intact before installation.

Should I adhesive-bond this or drill through the bumper?

This design uses factory bolt-holes — no drilling required. Use stainless or zinc-plated fasteners to secure the lip to existing mounting points on your bumper assembly.

What finish prep does carbon fiber need?

Carbon fiber comes with a protective clear coat. Sand and inspect the mounting surface before installation. If you plan to repaint or re-clear, sand lightly and apply your chosen finish over the factory base.
