BMW M135i xDrive (F40) exterior styling & carbon fibre parts
R44 Performance stocks 53 exterior styling parts for the 2019–2024 BMW M135i xDrive (F40). Parts include exterior styling, from brands including Genuine BMW, MHC, R44 Merch.
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 xDrive (F40), 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.
