MOTON BMW F80 M3 & F82/F83 M4 LCI 1-Way Coilover Kit - M 505 177SD (2015-2018)

The MOTON 1-Way Coilover Kit offers a precision performance upgrade for the BMW F80 M3 and F82/F83 M4 LCI models. Designed for enthusiasts who demand premium suspension control for spirited road driving and occasional track use, this system delivers improved grip, stability, and responsiveness without compromising everyday usability.

With 15 clicks of single-adjustable damping (combined rebound and compression), users can fine-tune their vehicle’s ride and handling to suit different road conditions or driving styles. The monotube dampers use an internal floating piston to separate oil and gas chambers, preventing aeration and maintaining consistent performance under pressure.

Each component is engineered for long-lasting performance using high-grade anodised aluminium, PTFE-lined spherical bearings, and low-friction seals. Ride height is fully adjustable via threaded damper bodies without altering spring preload. As with all MOTON suspension kits, the system is fully serviceable and rebuildable.

Key Features:

• 15-position single-adjustable damping (rebound & compression combined)
• Monotube dampers with internal floating piston
• Fully threaded bodies for ride height adjustment
• Lightweight anodised aluminium construction
• PTFE-lined spherical bearings for precise articulation
