AC Schnitzer Shocks & Springs Suspension Kit for BMW 1 Series F20/F21 (M135i, M140i) – Performance Damper & Spring Package, Lowering Suspension Set, Fast-Road Handling Upgrade, M Sport

AC Schnitzer Shock and Spring Package for BMW 1 Series F20 F21 including M135i and M140i

Give your 1 Series the stance, grip and confidence it deserves with this AC Schnitzer shock absorber and spring package. Purpose built for the F20 and F21 chassis, including M135i and M140i, this complete damper and spring set is a fast-road focused chassis upgrade that tightens body control, calms high-speed fidget and sharpens steering response while keeping daily comfort intact.

Because the dampers and springs are engineered to work together, you get balanced rates and consistent control you will not achieve with lowering springs on stock shocks. Expect flatter cornering, cleaner turn-in, reduced squat and nose-dive, and a smoother, more composed ride on broken British roads. We run this kit ourselves at MJ Modifications and customer feedback has been superb, with owners praising the real-world improvement in confidence and stability.

Why this chassis upgrade works

Upgrading both dampers and springs transforms the F20 and F21 platform into a more planted, responsive package. The AC Schnitzer tuning delivers tighter body control without a harsh ride, giving your M135i or M140i the balanced drop in ride height and the grip you are after. If you are searching for an uprated suspension kit, performance shocks for BMW 1 Series, a lowering package for F20 F21, or the best fast-road setup for M140i and M135i, this is a proven solution.
