Finish off your carbon fiber journey for your BMW G80 M3 with these Performance Style Carbon Fiber Diffuser side pieces. Crafted from genuine 2×2 dry carbon fiber, these exterior diffuser pieces will nicely match any other carbon fiber parts you already have on your car from RW Carbon. To ensure that the diffuser pieces have a lasting shine and shimmer, we finish off each piece with a thick and high-quality clear coat. Installation is 100% bolt-on, simply unbolt your factory gloss black rear bumper pieces and mount ours using the same mounting points. These can be paired with any of our carbon fiber center diffusers for the BMW G8x models. Our carbon fiber BMW G80 M3 rear diffuser sides will fit 2021+ BMW G80 M3 applications. Choose RW Carbon for your M3 carbon fiber needs and receive a product you can be proud to install on your vehicle.
