BMW M135i LCI (F20/F21) exterior styling & carbon fibre parts
R44 Performance stocks 70 exterior styling parts for the 2015–2016 BMW M135i LCI (F20/F21). Parts include rear side splitters, rear diffusers, side skirts and body kits, from brands including R44 Merch, Zaero Design, Maxton Design, R44 Tools, Genuine BMW, KIES Motorsports.
Exterior parts range from subtle OEM-style upgrades to full carbon fibre aero. Where a part comes in more than one finish, pre-preg and dry carbon give the most consistent weave and the lowest weight, while gloss black and paint-matched parts suit a factory look. Many splitters, side skirts and diffusers are designed as matching sets, so you can build a consistent look over time.
Every part on this page is listed for the M135i LCI (F20/F21), but bumpers and rear ends can differ between body styles, trim levels (such as M Sport or S line) and facelift versions – check the fitment notes on each product.
