Will this lip interfere with my front bumper or air dam at speed?

The TKO RBS profile is designed with clearance in mind for stock bumper geometry. Before final installation, test-fit the lip against your bumper and verify no contact points exist. If you've modified the bumper or splitter, measure the gap at the lowest point to ensure adequate clearance.

Should I adhesive-bond this or drill through for mechanical fastening?

Carbon fiber lip spoilers can be secured either way depending on your preference and bumper material. Adhesive-bonded installs are cleaner and reversible; mechanical fastening offers permanent attachment. Prepare your bumper surface thoroughly—sand and clean before applying adhesive, or lay out drill holes carefully if using fasteners to avoid cracking the carbon fiber.

Do I need to clearcoat the carbon fiber, or does it come finished?

This arrives uncoated. A UV-protective clear coat is strongly recommended to preserve the weave and prevent UV degradation over time. You can match your bumper paint or apply clear coat alone to maintain the raw carbon look—either way, proper sealing extends the life of the piece significantly.
