Will this interfere with my trunk seal or bumper gaps?

The lip is designed to bolt flush to the bumper using factory mounting points. Measure the gap between your bumper and fender before install — if gaps are significantly wider than stock, the lip may not sit flush. Sand and test-fit the mounting surface for a clean, even installation.

Can I use adhesive instead of drilling new holes?

This lip uses factory mounting points, so no new drilling is necessary. If you prefer adhesive-only mounting over bolts, the FRP surface accepts epoxy-based automotive adhesives — but factory bolts are the recommended method for durability and alignment.

How does this perform at highway speeds?

A front lip at this height is designed for aesthetic enhancement and minor downforce, not high-speed aero. Secure all fasteners tightly and check them after your first few drives to ensure the lip stays stable under sustained acceleration and wind load.
