Will the lip sit flush with my bumper or stick out slightly?

The Venom profile extends below the stock bumper line for that aggressive look. Dry-fit the two pieces on your bumper before final fastening to confirm your desired gap and alignment.

Should I use adhesive, bolts, or both to secure the pieces?

Carbon fiber lips typically work best with mechanical fasteners (bolts through the mounting points) to handle road vibration and speed. Use stainless steel hardware to avoid corrosion where the fasteners meet the carbon.

Does real carbon fiber need special care or will it crack from road debris?

Carbon fiber is extremely durable and won't break from typical road impacts like plastic would. The main benefit is that it won't fade or yellow under UV like painted plastic bumpers do. A clear protective coat is recommended to extend the finish longevity.
