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.

    Decent value for the money.
    Size: 6FT*6FT, Color: Grey
    Was easy to assemble. Instructions were clear. Tools were supplied. It really needs to be assembled wherever you're going to be putting it as it can come apart easily when moved. The cross bars simply fit into open ended plastic 90 degree female ends. Overall for the money and to just have some division in a room it's a good value.

    Garbage
    Size: 6FT*6FT, Color: Black
    This product is absolute garbage! It literally took all day to put it together and if the air conditioning blows on it the wrong way than the whole thing top over and it falls apart. It’s not made of quality material and is very flimsy. The only reason I’m not returning it is because it’s too difficult to put together and I don’t wanna spend that much time trying to take it apart. Do not buy this!

    Cheap
    Size: 6FT*6FT, Color: Black
    They serve their purpose as long as you leve them in one place and not moving them around and they're kinda flimsy and some of the velcros are cut too short and can't stay closed

    Pretty good, especially for this price point.
    Color: Beige, Size: 21.5"- 1 Panel
    This is merely a piece of cloth stretched between the frame borders, but it works perfectly. It arrived quickly, all parts present and in good condition. I didn't put the castors on, as it will be more or less always in one position. I simply attached some felt sliders on the bottom to prevent scratching the floor and to allow clearance for the center screw (which is not flush fit). Overall, a reasonable deal for the price point.
