Will this lip interfere with my trunk seal or bumper assembly?

No. The Hyper Flow design mounts to the lower fascia without contacting the trunk lid or affecting bumper panel fitment. Verify your bumper's mounting points and any aftermarket widebody panels before final installation to ensure clearance.

Does adhesive or bolt-through installation work better for carbon fiber?

Carbon fiber tolerates both methods well. Adhesive-only approaches are cleaner; drill-through mounting adds security if you're tracking the car or in high-vibration environments. Sand the mounting surface clean and follow your adhesive or fastener manufacturer's specifications for the strongest bond.

Will the finish hold up at highway speeds without additional sealing?

Carbon fiber is stable at any road speed. A UV-protective clear coat applied before installation extends the weave's color retention and shields it from UV fade. Without it, the finish will gray over time but the structural integrity remains unaffected.
