Wet Carbon Diffuser Fins for BMW Series 4 G22 / G23 Pre-LCI M Sport

Made with real carbon fiber using a Wet Carbon process, these diffuser fins are finished with a high-gloss clear surface and UV protection. The visible carbon-fiber weave adds depth to the lower rear section and changes in contrast as light moves across the individual surfaces.

Within the diffuser area, the fins emphasize the existing vertical geometry and make the lower rear structure easier to read from directly behind. The carbon-fiber contrast creates clearer separation between the diffuser lines and surrounding surfaces, adding visual depth without changing the original rear-bumper proportions.
