Adjustable Ride Height Spring Kit for BMW F30 340i LCI Saloon

Transform the way your 3 Series turns, stops and puts power down with the MSS Sport adjustable spring system. This premium performance spring set delivers a purposeful drop, sharper responses and a cleaner stance while keeping daily comfort intact. It is a brilliant coilover alternative for drivers who want road-friendly compliance with genuine fast-road and occasional track capability.

Why this upgrade stands out

• Adjustable drop 0 to 30 mm for the perfect stance and arch gap reduction
• Compatible with original shock absorbers, including adaptive electronic dampers
• Noticeably crisper turn-in and reduced body movement for confident cornering
• Improved traction out of bends with less squat and dive under hard braking and acceleration
• Everyday comfort retained for UK roads and longer journeys
• Designed and engineered in the UK, precision manufactured in Germany
• Backed by a lifetime warranty from MSS Suspension

How it delivers grip and control

MSS Sport uses a unique dual-stacked, triple-rate spring layout to broaden the working range of the suspension. Two active springs and three distinct rates manage small bumps and big hits with composure, giving you stability at speed and compliance over rough tarmac. The result is a chassis that feels planted, predictable and confidence inspiring without the harshness you often get from one-rate lowering springs.

We have installed this kit on customer 340i builds and the response has been outstanding. Drivers report tighter control with far less roll, a smoother flow over uneven roads and the ability to dial in the perfect ride height for both daily use and spirited weekend drives.
