Rear Diffuser

CarbonXtreme Rear Diffusers — dry-carbon aero modeled from OEM CAD for factory-grade fitment across BMW platforms. Designed around ramp/strake geometry, departure angle, and exhaust clearance, our diffusers balance wake control with everyday usability. Prepreg autoclave construction keeps weight down; PPG clear coat preserves clarity and UV stability on exposed fins and edges. Clean weave symmetry, precise mounting logic, and options from purposeful profiles to subtle OEM-style pieces.

This is where a BMW stops looking “stock” and starts feeling yours. Choose the diffuser that speaks to you, then pair it with a front lip or wheel finish for a cohesive stance. CarbonXtreme dry-carbon brings that quiet, unmistakable premium—a consistent weave with crisp, glass-like reflections, finished in PPG and installed with precision. Even non-enthusiasts can tell it’s the real high-end at a glance.
