PSM has always had a different approach to aerodynamics. Aggressive, unconventional and far from what you see on an everyday build.

Now introduced to the WBS G8X M3/M4 Collection.

The PSM rear diffuser is manufactured as one complete, oversized piece, using 100% genuine 2x2 pre-preg carbon fiber, following the same material and craftsmanship standards across the WBS G8X lineup.

An unmistakable rear-end design, made for those who believe ordinary was never an option.

Compatible With

BMW M3 G80 | M4 G82 G83 YEAR: 2021-ON

Installation

Direct fitment, replacing the OEM rear diffuser.

Material

Authentic pre-preg vacuum-formed DRY carbon fiber featuring a 2x2 weave identical to BMW OEM carbon fiber components.

WBS diagonal racing-stripe background with subtle carbon-weave accents

Born to revolutionize the world of modification solutions.

I purchased a ducktail spoiler and front lip from WBS, and I couldn't be happier with the experience. The quality of both products is amazing, and the customer service was absolutely first-rate.

I also chose to have both parts installed, and the work was completed to an exceptionally high standard. Everything fits perfectly and looks fantastic. I highly recommend WBS and would definitely use them again in the future!

Can’t say enough about the customer service from Emad and quality of products . Can’t imagine how anyone could justify going anywhere else. Does wonders for the look of the M cars and very competitive pricing. Absolute 5 star total experience! Absolutely top notch fit and finish at least as good as BMW’s limited carbon fibre.
