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

Great grinder! Fun to use. :)
Color: Silver
Wow, very well constructed, grinds all sorts of things perfectly. Completely happy. Looks great, super easy to use, nice size, little glass jar, very quiet, love that it's true ceramic. Handle comes off easily to store. Nice! :)

Great coffee grinder!
Color: Silver
Amazing product. Easy to use and has different grades of grinding. Zero noise compared with an electric grinder and more control of the results (consistent). His size and weight make it portable and easy to carry.

Quite good as a start grinder
Color: Silver
Very good burr grinder with very functional adjustments. Holds the perfect amount in 1 go for my pour over setup. My only critique is that is has 3 unconnected hopper sections that are quite small and hard to hit. I have to be very careful to not spill and one can fill before the other 2 causing some difficulties closing the crank, but it just takes some self adjustments to get around. Overall I'm very pleased with it for the price.

Great Quality, Great Price.
Color: Black
I have used this for a few days now and it works great. It is very well made and has a large range of adjustability. It is quite small and easy to store. Definitely worth the money.

Nice Grinder at a Great Price
Color: Black
I bought this to use primarily as a travel grinder and found that it is great for every day use. It is not meant for large amounts but it is perfect for single, smaller brewing situations. The grind selection worked well and I "dialed" the proper ground size for my single sized pour over coffee maker.
