Diffusore posteriore in fibra di carbonio V.1 + scarico Milltek Sport Bmw 1 F40 M-pack / M135i

Maxton Design have been making aftermarket styling parts since 2012, and they're one of our most popular brands. Splitters, spoilers, skirts and diffusers built to fit specific models, for a sharper look without a full body kit.

Most parts are tough ABS plastic with a UV coating, and ship with a protective film already on. 

Some come ready to fit, some need painting (primer first), and a few of the larger fibreglass items need prep and paint before fitting. Check the description above for this part's material and finish.

Will it fit my car? Selecting your model gets you close, but the best check is to compare the product images on this page against your actual car. Look at the bumper shape, the vents and where the part sits. Factory sports trims (R-Line, S-Line, M Sport, ST-Line, AMG Line, FR) often have different bumpers, so a standard-fit part won't suit them. If the photos don't match, message us before you buy.

Fitting: Follow Maxton's instructions for your part, every time. We can't warranty anything fitted incorrectly, so if you're not confident, use someone who is.
