Description
Maxton Design Rear Side Flaps V2 for BMW M135i (F70)
Add a sharper rear profile to your M135i. These rear side flaps extend the line of the bumper and splitter, giving a clean, motorsport-inspired look without hurting everyday use.
Fitment
Designed for the BMW M135i F70, 2024 onwards. Fits only with Maxton Design Rear Side Diffusers V2 (BM170MCNC-RSD2) installed. Use our vehicle lookup or see the Vehicle Fitment tab to confirm compatibility.
Material and build
Made from ABS plastic used by many car makers for exterior parts. It is light, tough, and resistant to weather, UV, and heat. Supplied in durable black, ready to fit or paint if required.
Why it matters
Crisp, defined edges at the rear improve the cars stance and visual width. Any aerodynamic effect is mild, but the added stability at speed can be noticeable on motorways.
Installation and safety
Direct fit using the included hardware. Test fit first, clean mounting surfaces, and tighten fixings evenly. Check fasteners after the first few drives. Do not block sensors or reflectors.
