Will this lip interfere with the trunk seal or undercarriage at speed?

The UTech lip is designed to clear the factory bumper assembly and undercarriage. Verify ground clearance on your specific setup before installation—factory suspension geometry varies slightly, and aggressive lowering may require fitment review.

Does this require drilling, or does it use the factory brake light cutout?

This lip mounts to existing factory attachment points—no drilling required. If your bumper has an OEM brake light opening, the lip geometry is designed to work around it without modification.

Should I use adhesive or drill fasteners for added security?

The design relies on factory mounting holes. You can supplement with quality automotive adhesive if desired, but ensure the FRP surface is clean and dry. Sand lightly and let any primer cure fully before applying adhesive—this ensures a stable, long-term bond.
