Will the lip interfere with my trunk seal or bumper fitment?

The C Speed profile is engineered as a front lip under spoiler, meaning it sits below the main bumper line and does not interact with trunk seals. Verify OEM mounting points on your bumper before final fastening to ensure alignment with existing holes.

Should I drill new holes or use adhesive to mount this?

Carbon fiber lips typically secure via existing OEM fascia fastener locations or self-tapping fasteners into the bumper substrate. Adhesive alone is not recommended for high-speed stability. Reference your vehicle's mounting pattern and use mechanical fasteners appropriate for carbon fiber — avoid over-torquing.

Will this lip stay stable at highway speeds?

A properly fastened carbon fiber lip is rigid and stable at speed. Ensure all connection points are tight and use corrosion-resistant hardware. Check fasteners after your first 100 miles and periodically thereafter, as vibration can loosen hardware over time.
