The TRE Pre-preg Performance Rear Diffuser is constructed using advanced pre-preg carbon fibre manufacturing techniques for perfect fit, finish and durability.

Designed by TRE specifically for the BMW M2 & M2 Competition.

What’s in the box

• 1 x TRE Carbon Fibre (pre-preg, 2×2 Weave) Rear Diffuser

Installation

Installation 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.

NOTE: For the most precise fit, we recommend removing the rear bumper and securing the tabs with a screw from the inside. This ensures they are firmly held in place, preventing any movement or misalignment. By fastening the tabs this way, the installation will be more secure and long-lasting, reducing the risk of any gaps or looseness over time.
