H&R Sport Lowering Springs Kit 25mm - BMW 1 Series F20/F21 M135i & M140i (2011-2019, RWD & xDrive, Adaptive Drive Compatible) - Part 28835-1 - TÃœV Approved

H&R 25 mm Ride-Height Spring Set for BMW 1 Series F20 F21 M135i M140i

Give your fast 1 Series the stance and dynamics it deserves with this premium H&R 25 mm drop spring set. Tailored for BMW F20 and F21 M135i and M140i, these precision-wound coils lower the car by approximately 25 mm front and rear for a cleaner arch fill, a lower centre of gravity and sharper steering response on UK roads.

Built in Germany from high-tensile spring steel and finished in a durable powder coat, H&R springs are a trusted upgrade for drivers who want road-friendly comfort with a big step up in control, grip and turn-in. Perfect as a coilover alternative for daily-driven cars that still see spirited use.
