The MHC+ DF1 carbon fibre rear diffuser for the BMW G80 M3 and G82 M4 is an OEM+ rear styling upgrade with a racing LED brake light.

By replacing the factory gloss black diffuser with an MHC+ carbon item, you are enhancing the rear of your vehicle with outstanding quality, increased road presence and a far more up-market aesthetic.

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.

Why upgrade your OEM carbon fibre diffuser to the DF1?

The DF1 rear diffuser features a new and improved style to give your G8X vehicle a more unique look. Enjoy a more aggressive design without compromising on OEM-like quality and finish. The best thing about upgrading is that you can sell your OEM diffuser to recoup some of the cost, making your new DF1 diffuser much more affordable. OEM G8X carbon diffusers can be sold for around £500 based on condition!

Wonderful Room Partition !
Color: Black, Size: 88"- 4 Panel
This product is made very well, packaged, and assembled with no problems. All parts and tools are included (except a Phillips screwdriver.) I put this item all together by myself on a bed to make it easy and simple. I made sure that every screw head was attached where the recessed dimples are located on the vertical poles, just don't overtighten anything. Everything fits like a charm, good quality, looks great, perfect height, rolls with ease, proper privacy, really impressive ! I got the 4-panel in black color. I would certainly buy this item again ! Thank you !
