Will this lip interfere with my bumper or splitter at highway speed?

No. The MPX profile is engineered to sit cleanly below the front fascia without creating air pocket turbulence or downforce instability at sustained speeds. Verify ground clearance on your setup before installation, especially if you're running lowered suspension.

Should I install this with adhesive or drill through the bumper?

This lip bolts to existing factory attachment points on the lower fascia. Adhesive alone is not recommended for carbon fiber front lips due to road stress and vibration. Use the factory mounting locations and fasteners to secure it properly.

Does the clear coat protect the carbon weave from UV damage?

Yes. The clear coat finish provides UV protection and keeps the weave looking sharp. Over time, exposure may dull the finish slightly. Regular washing and occasional wax application will maintain the appearance and protect the coating from environmental contaminants.
