Rather than replace the full diffuser and have potential fitment challenges with various exhaust options Dinan has opted to retain the factory gloss black lower portion of the diffuser and only replace the upper diffuser surround with a carbon fiber accent piece. This solution not only guarantees the carbon cosmetics will always play well with any personalization of the exhaust that is adopted but also offers an economical option compared to much pricier alternatives. Together with the Dinan Rear Side Splitters, the combination creates a "full" rear diffuser that is restrained but elevated and creates a nuanced OEM+ option for the marketplace.
- 2x2 gloss twill dry carbon fiber (pre-preg) manufactured to be impact resistant, durable and strong
- Clear coated for maximum UV protection and fade resistance
- Utilizes factory mounting tabs for an easy installation with a clean fit and finish
- Pair together with the Dinan Rear Side Splitters to complete the full rear look
