The rear is what they stare at in traffic, and from the factory the diffuser area is a big stretch of plain black plastic. It is the obvious place for carbon, and the easiest place to get it wrong.\u003c\/p\u003e\n\u003cp\u003eThe Dinan Gloss Carbon Fiber Rear Diffuser Surround replaces the upper diffuser surround on the BMW G80 M3 and G82\/G83 M4 with a real carbon fiber accent piece. It is 100% genuine 2x2 gloss twill dry carbon fiber, manufactured from pre-preg and clear coated for UV protection and fade resistance. No wrap, no hydro-dip.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhy Dinan Built a Carbon Fiber Rear Diffuser Surround, Not a Full Diffuser\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFull replacement diffusers often clash with aftermarket exhausts because every tip layout is different. Dinan kept the factory gloss black lower diffuser and replaced only the upper surround. That avoids fitment problems with the many exhaust configurations out there and keeps the cost sensible, while putting carbon exactly where eyes land. On the G80 M3, add the Dinan Rear Side Splitters for a complete OEM+ rear end.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eInstall, Fitment and Availability\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe surround uses the factory mounting tabs for an easy install with a clean fit, and Dinan quotes about 1 hour of labor. It is a styling part that does not affect emissions, and Dinan lists it as legal for sale on all vehicle types. Dinan part number D980-0049. Sold by AutoTecknic, an authorized Dinan dealer.
