BMW F90, M5 Carbon Fibre MP Style Rear Diffuser Lip

BMW F90 M5 Carbon Fibre MP Style Rear Diffuser Lip

Add definition to the lower rear of your BMW F90 M5 with this MP Style Rear Diffuser Lip — a carbon fibre insert that fits into the existing valance and gives the back of the car the strake pattern BMW left out.

This is the lighter-touch option in our F90 rear range. Rather than replacing or covering the whole lower bumper, it sits in the recess between the exhaust exits and adds a run of deep vertical fins exactly where the eye goes. The car keeps its factory proportions and simply gains the detail it was missing.

The MP profile matches BMW's own M Performance styling language — clean fins, no wings, no extra corner pieces — so it reads as an option box rather than a modification.

Moulded in carbon fibre with a gloss clear coat and formed to the exact contour of the F90 valance, it fits to existing points with nothing cut or drilled.

Please Note

Please select your exact model above so we can confirm the correct part before dispatch.

Professional installation is recommended. The lip should be offered up and aligned across its full width before any fixing is tightened.

Carbon fibre is a natural woven material. Minor variation in weave pattern between pieces is characteristic of the material and not a defect.
