Sale price£799.99


This MHC BMW G80 M3 & G82 M4 OEM Style Rear Diffuser in Pre Preg Carbon Fibre provides the extra aggression while matching Carbon Quality with BMW. 

MHC have used the stock Gloss Black rear diffuser as a base design as they wanted to make something that is the perfect OEM+ look. MHC has added an additional fin in the centre of the diffuser as well as slightly increasing the fin size. All design work has taken 3D data from the vehicle to ensure the product is a direct replacement for your current diffuser. 

The product is made from the latest Pre Preg Carbon manufacturing processes and aluminium moulds to ensure unrivalled quality and fit. Please see below for the installation video.


  • Improved OEM styling
  • Direct replacement for the original diffuser  
  • Crafted from Pre-Preg carbon fibre with a 3k 2x2 weave (OEM Style)
  • Coated in a high gloss lacquered finish


There are a variety of reasons why we recommend it to our customers. It’s far stronger than normal carbon, meaning increased durability and life span in the long term. Spend a little more now so you don’t have to come back later for replacements because you looked at your carbon the wrong way and hurt its feelings.

Pre Preg carbon is more consistent quality-wise when coming out of the mould, meaning less chance for issues or imperfections that would otherwise be undesirable in the finished product. The process eliminates air bubbles and results in a smooth, glossy surface more easily. This makes for the ideal part to compliment your car. If you are all about weight saving, Pre Preg is 70% lighter than alternative carbon options. It is the obvious choice when you’re concerned about performance.
