AUTOID Carbon Fibre Rear Diffuser for BMW M2 & M2 Competition


Engineered from the outset to deliver on our promise on individuality and quality, our rear diffuser for the BMW M2 and M2 Competition is an extension of the OE design language. It sets off the back end of the car and adds real definition to the diffuser area - great to showcase your exhaust system.

Recently refreshed, we have now included 3 creases in the top section of the diffuser, specifically added to make the diffuser more cohesive with the design found in the front bumper of the M2 Competition.


What's included:

  • 1 x AUTOID Carbon Fibre (CFRP, 2x2 Weave) Rear Diffuser



Fitting takes approximately 20 minutes. On each end of the OEM diffuser, it's attached underneath by one 8mm hexagon bolt. Remove both. Then remove the 6 plastic pop rivets using a pry tool. Six rivets and two bolts in total. Start by pulling both the far left and right sides of the diffuser first, as these clips will pop out easily. Then work carefully to remove the centre clips of the diffuser - these are much tighter and will require more force. 

Once removed, install the new AUTOID rear diffuser with the bolts and rivets from the original diffuser. 

A video tutorial will be coming soon. 

Alternatively, we can fit onsite. Please contact us at in order to make an appointment.

We quality control every single item that we dispatch from our shop. Many sellers online ship their products straight from overseas, meaning they have not been quality controlled. If you order one of these parts you could receive a part that is damaged, has scratches in the clearcoat, or overall poor carbon fiber construction. By choosing AUTOID, we make the promise to deliver a consistent, quality product that is shipped from our shop in London, not from China or Taiwan. One final benefit is our warranty, as above, this is a minimum of 2 years and is as long as a lifetime on our TRE items.
