Dinan Rear Diffuser Surround - 2021-2025 BMW M3/M4

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.

Features:

  • 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

Perfect
Color: White, Number of Items: 2
These are the perfect size. A little long cumbersome putting them together. They look very nice for a small nightstand

Was easy to put together, and it's sturdy. It didn't come with any white dots to cover screw holes, so I ordered as some on my own.

GOOD BUY
Color: Grey, Number of Items: 1
This is a good sturdy table. It is the perfect size for an end table or nightstand. The USB ports and Outlets really come in handy. It is made out of real wood which is rare, it is definitely worth money.
