MSS Sport Adjustable Spring Set for BMW F21 M140i 3dr

Give your F21 M140i the stance, control and composure it deserves with the MSS Sport adjustable spring set. This performance spring upgrade is engineered to deliver a precision drop, sharper steering response and real-world comfort on UK roads, while remaining fully compatible with factory adaptive dampers.

Using MSS’s dual-stacked, triple-rate spring technology, this kit markedly reduces body roll, pitch and squat for confident cornering and consistent traction. Turn-in is crisper, mid-corner balance is more stable and exit grip is improved, yet ride quality remains compliant for daily use. Designed and engineered in the UK and manufactured in Germany, it is a premium coilover alternative for drivers who want height adjustment without sacrificing refinement.

We run this setup ourselves on our M140i and our customers love the transformation. Expect a more planted feel, better braking stability and a purposeful road presence with the arch gap dialled in exactly how you want it.
