Will this lip interfere with my factory bumper seal or trim pieces?

No. This lip is engineered to fit within the stock bumper opening using existing factory mount points. Before installation, verify your bumper is in stock condition and free of damage that might affect the gap.

Should I apply clear coat, or leave it raw carbon?

Clear coat is recommended. Raw carbon fiber is porous and susceptible to UV damage and minor discoloration over time. A quality automotive clear coat protects the weave and maintains the finish for years.

Does this come with mounting hardware?

The assembly ships as-is. Confirm your vehicle has factory-drilled mounting locations in the bumper before ordering. Standard automotive fasteners will secure it; refer to your service manual for proper torque specs.
