15' F30 335i M3 Rear Bumper Conversion

Cyrca · 12-22-2018, 03:36 PM

Anyone have experience using M3 diffusers on an f30 with an m3 conversion kit bumper?

I am REALLY trying to figure out how to get a replica vorsteiner diffuser to fit well without having to do a whole bunch of fiberglass work myself.

I have no interest in being an M3 wannabe, if I could find a decent diffuser setup for the M Spot bumper I would also be open to purchasing that.

TY!

I got a carbon fiber diffuser off eBay that fits pretty decent. The fins don't extend as far down as your image, and doesn't wrap to the sides of the bumper (I do like the look you have above though). I have the OEM m-sport package.

Here is an image of mine installed:

The top lip has tabs to "clip" into the plastic bumper, and one side doesn't snap in as good as it should, but after 2 years, nothing has moved, so I'm happy.

I do like the wrap around wing look of your image though. It would match the front lip I installed.
