Will this lip interfere with the front bumper or undercarriage at speed?

No. MS-R lips are engineered to sit low without catching on driveways or speed bumps when installed correctly. Verify clearance during test drives at your typical driving angles — most buyers find street use problem-free once mounted.

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

Most install guides recommend mechanical fastening (bolts through factory mounting holes or new holes drilled into the bumper fascia) paired with FRP-grade epoxy for long-term durability. Adhesive alone is not recommended for a lip that experiences road turbulence. Reference your vehicle's bumper structure and choose fastener locations that avoid internal reinforcement ribs.

Does this require any brake light or sensor cutouts?

No. This is a lower front bumper lip — it does not interact with brake lights, sensors, or fog lamps. Installation is purely cosmetic and structural with no electrical routing needed.
