E92 M3 Track spec rear diffuser
This rear diffuser is the big daddy, the ultimate racing diffuser upgrade for your E92 M3. This is a full size rear diffuser that assists with air transition beneath the vehicle at high speeds, reducing drag and increasing the speed of the air travelling under the vehicle and allowing it to escape rapidly thus increasing the high pressure area on top of the vehicle ultimately increasing mechanical grip.
This kit is highly durable and impact resistant, you have the option of 2mm and 3mm thick aluminium fabrication depending on how rough you intend to tread this beauty. #mm is geared toward time attack applications as it can withstand heavier track day wear and tear.
This kit only comes with generic mounting hardware and no pre drilled holes so it requires custom installation, it is highly recommended that this kit be installed professionally.
