BMW F30 Rear Diffuser Gloss Black – F30/F31 M Performance Front Splitter & Diffuser Kit (2012–2019)
This BMW F30 rear diffuser gloss black finish is part of an M Performance-style front splitter and rear diffuser kit built specifically for BMW 3 Series F30 Saloon and F31 Touring models from 2012 to 2019. It adds a bold, aggressive edge to both ends of your car while sharpening the overall aerodynamic profile.
BMW F30 Rear Diffuser Gloss Black – What's Included
The kit includes a front lip splitter in M Performance style with side winglets, plus a multi-fin rear diffuser finished in gloss black. The gloss black finish delivers a deep, high-shine look that complements any body colour, while the front splitter improves downforce and the rear diffuser sharpens airflow and rear-end styling. Built from durable ABS plastic, the kit is strong, lightweight, and designed to hold up in all weather conditions.

Absolutely transformed the look of my car. Took about an hour to fit with the tape and a couple of clips. Mounting points matched up first time, dead easy. Delivery was quick too.
Massive upgrade over the standard bumper. The ABS plastic feels solid and thick, not the flimsy stuff you get elsewhere. Needed a tiny bit of adjustment but nothing major. Would buy from KEUBE again.
Fitted this at the weekend. Gaps are even all the way across, looks completely OEM. Worth every penny.
Exactly what I wanted for the build. The ABS plastic feels solid and thick, not the flimsy stuff you get elsewhere. Delivery was quick too.
Cracking bit of kit. Sits flush against the bumper with no gaps. Lined up perfectly with the factory mounting points, no drilling needed. Would buy from KEUBE again.
