The UV-resistant gloss clear coat is factory-applied and ready to install. At up to 50% lighter than the OEM steel equivalent, it reduces unsprung weight for measurable gains in acceleration, braking balance, and cornering response.

No. Seibon diffusers are designed to mount under the existing rear bumper using factory clip locations. Always pre-fit before making any modifications.
What is the warranty?Seibon provides a fitment guarantee and a 6-month limited clear coat warranty. Under the Magnuson-Moss Warranty Act, this product does not void your vehicle's factory warranty.
Will this affect exhaust heat near the rear bumper?Carbon fiber has moderate heat resistance, but prolonged direct exhaust heat can affect the clear coat over time. Ensure exhaust tips are directed away from the diffuser surface, especially on high-output vehicles.
Is painting required?No. The gloss clear coat finish is factory-applied and ready for installation. Painting is optional for color-matched applications.
Can I install this at home?Yes. The installation is straightforward with basic hand tools and does not require professional bodywork experience.
How do I maintain the finish?Wash with mild soap and a microfiber cloth. Apply UV-protectant wax regularly. The underside of the diffuser is exposed to road spray; inspect for chips periodically.
Is this compatible with aftermarket exhaust systems?Fitment is based on OEM rear bumper and exhaust tip geometry. Verify exhaust tip positioning with aftermarket systems before purchasing.
Does this affect ground clearance?On stock-height vehicles, Seibon diffusers maintain adequate ground clearance. On significantly lowered vehicles, measure clearance before purchasing.
