Engineered from the outset to amplify the already bold backend on the G80 and G82 platform, this pre-preg carbon fiber diffuser is the perfect pairing to add even more aggression to your car. 

Made in pre-preg carbon fiber to ensure perfect fitment and durability, the 2x2 weave matches any OEM carbon you may already have on your car. Want the full carbon kit? Pair with a TRE Rear Spoiler and front splitter.

TRE have developed this product to retain all the OEM mounting points, just as the original diffuser does. This has been done using advanced 3D CAD.
