Ohlins BMS4I10 Road & Track DFV Left Rear Shock Absorber Mini Cooper R50 R53

The Öhlins BMS4I10 is an individual left rear shock absorber from the renowned Öhlins Road & Track suspension line, engineered for the 2002–2006 Mini Cooper (R50) and Mini Cooper S (R53). This single rear damper unit is a direct-fitment replacement that delivers the performance and ride quality Öhlins is celebrated for worldwide, allowing targeted replacement or upgrade of just the left rear corner of your suspension system.

Featuring Öhlins' patented Dual Flow Valve (DFV) technology, the BMS4I10 allows drivers to quickly dial in damping stiffness with a simple turn of the adjuster knob — transitioning from a compliant street ride to a focused track setup without tools. The DFV simultaneously adjusts all four damping zones: low- and high-speed compression and low- and high-speed rebound.

Key Features:

• DFV (Dual Flow Valve) — patented single-knob adjuster controls compression and rebound simultaneously
• Conventional rear shock absorber design with separate spring preload adjuster
• Coil spring included — rear spring rate of 50 N/mm (286 lbs/in)
• Approximately 10–25 mm lower than stock with recommended setup
• Compatible with original OEM top mounts
• Lightweight construction with aluminum components for reduced unsprung weight
• Fully rebuildable for long-term serviceability
• Corrosion salt spray tested to ISO 9227 standards
• Includes dust cover and mounting hardware
• Backed by Öhlins' worldwide 2-year limited warranty

The BMS4I10 is part of the Öhlins BMS MI10S1 Road & Track system for the Mini R50/R53 platform. Whether replacing a worn damper or upgrading individual corners, this unit delivers the same race-derived performance and precision that has made Öhlins the benchmark in motorsport suspension technology.
