Will this interfere with the front bumper or splitter on aggressive setups?

The lip is engineered to sit flush with the factory bumper profile. If your vehicle runs a lowered suspension or aftermarket splitter, verify clearance between the lip's lower edge and any ground-facing components before final mounting. Test fitment at ride height in your driveway first.

What finish prep is needed before installation?

Carbon fiber comes raw or with a clear coat applied. Sand and prep the mounting surface on your bumper with appropriate grit before bonding or fastening. If the lip arrives unfinished, sand and apply your chosen clear coat to protect the weave from UV exposure and maintain the finish long-term.

Does adhesive or mechanical fastening work better for mounting?

Both methods work depending on your preference and bumper material. Adhesive offers a seamless look; mechanical fasteners (bolts or clips through the bumper) provide adjustability and easy removal. Verify your bumper's mounting points and choose the method that suits your install goals and reversal plans.
