Will this interfere with my front bumper or splitter when installed?

Check your OEM bumper geometry and any existing splitter clearance before drilling or bolting. This lip mounts to your lower bumper fascia — measure the gap between your current setup and the undercarriage to confirm fitment in your specific setup.

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

FRP pieces of this size perform best with mechanical fastening (bolts through pre-drilled holes). Adhesive alone will not provide the rigidity needed at highway speeds. Drill through your bumper or use existing holes if your bumper design allows for it.

Will this stay stable at high speed or track use?

One-piece FRP construction is significantly stiffer than plastic bumper covers. Proper mechanical mounting and adequate fastener spacing prevents flutter and movement. Verify all fasteners are tight before extended driving and inspect mounting points periodically for any loosening.
