MHC+ BMW G80 M3 G82 M4 Performance Style Rear Diffuser In Pre Preg Carbon Fibre is a beautiful OEM+ rear diffuser for the G8X platform. The design is inspired by BMW's M Performance rear diffuser and is constructed using industry-leading pre-preg carbon fibre - see benefits below. As you would expect with any MHC+ product, the carbon quality is outstanding and the fit/finish is impeccable. The MHC+ OEM Style Rear Diffuser adds aggression as well as a more premium look and feel. It makes the G80 or G82 feel so much more special and you'll find yourself always looking back at it every time you get out.
The carbon fibre weave matches BMW's factory carbon weave, allowing the MHC+ OEM Style Rear Diffuser to integrate seamlessly.
Why choose pre-preg carbon fibre?
Unlike normal carbon fibre, pre-preg carbon is reinforced for increased strength and durability. It can also be an astonishing 70% lighter than other carbon options, ideal for weight-saving. Quality-wise, pre-preg carbon is far more consistent meaning the chance of imperfections is dramatically reduced. The manufacturing process eliminates undesirable air bubbles and results in a perfect, sleek, smooth & high gloss finish, making the ultimate part to complement your vehicle.
When you buy pre-preg, you are investing in a higher quality, longer-lasting part that will outlast other forms of carbon fibre and potentially save you money in the long term.
