Upgrade the back end of your 1 Series with a precision Maxton Design V1 lower bumper insert

Part number: BM-1-F20F-M-CNC-RS1A

Give your post-facelift BMW F20 or F21 a sharper, motorsport-inspired finish with this Maxton Design V1 rear valance. Engineered specifically for 2015 to 2019 models, including the M135i hatch, this premium lower diffuser panel integrates cleanly with the factory bumper for a true OEM plus look. It is made from high quality ABS, the same type of material widely used for exterior body components, delivering strength, impact resistance and everyday durability.

We have installed this part on customer cars at MJ Modifications and the feedback has been superb. Fitment is consistent, the styling is assertive without being excessive and the overall transformation is exactly what enthusiasts want from a quality aero piece. It finishes the rear profile properly, tightening up the stance and complementing other performance styling upgrades.
