Will this lip interfere with trunk seals or body gaps?

No. The Alpine profile is designed to sit within the existing bumper cavity and does not extend beyond standard body lines. Verify fitment against your vehicle's OEM bumper contours before final installation to ensure proper clearance at all mounting points.

Should I use adhesive or drill through the bumper to mount this?

Both methods work depending on your preference. Adhesive creates a cleaner install with no new holes; drilling provides permanent, removable mounting. Verify the existing mounting points on your bumper assembly first—most installs leverage factory holes to minimize new penetrations.

Will this stay stable at highway speeds?

Yes. The single-piece construction and low-profile Alpine design create minimal aerodynamic load. Secure installation through either method and proper surface prep ensure durability at speed. Use quality automotive-grade adhesive or fasteners rated for exterior panel work if drilling.
