Can anyone identify this rear diffuser?

_ts · 04-04-2023, 02:49 PM

I just put a deposit on a pretty clean 2015 M4 for sale with 30k on the odometer. It has an aftermarket rear diffuser on it. Can anyone identify it? Is it a quality diffuser or cheap?

This seems like a gloss black 3 peice diffuser. Many companies sell them so it might be hard to track down who it’s from.

How much would it cost to revert it back to stock?

Nothing to be removed, would just need to be replaced with a stock BSM painted diffusor which I just happen to have for sale.

That looks like an aftermarket V3. More than likely not a quality piece.

Get yourself a nice Vorsteiner Carbon Fibre Diffuser, they look superb.

Diffuser and trunk wing are cheap aftermarket.
