D2 Racing D-MI-03 RS Series Coilover Kit 02-06 Mini Cooper

The D2 Racing RS Series Coilover Kit (D-MI-03) is D2 Racing's flagship suspension system and has earned its reputation as an affordable mid-level performance coilover for over two decades. Engineered for the Mini Cooper enthusiast who wants a meaningful upgrade over stock suspension without sacrificing daily drivability, the RS Series strikes an ideal balance between spirited street performance and occasional track use.

At the core of the RS Series is a 36-way damping adjustable monotube shock design, giving drivers precise control over compression and rebound characteristics. Independent ride height and spring preload adjustments allow you to dial in your ideal stance and handling without compromising full strut stroke travel — a critical advantage over lesser coilover designs. Ride height can be lowered 60mm to 100mm below the factory setting.

Key Features:

• 36-Way Damping Adjustment — Single knob controls both compression and rebound for easy tuning
• Monotube Shock Design — Delivers consistent performance and improved heat dissipation over twin-tube designs
• Separate Height and Spring Preload Adjustment — Maintains full strut stroke at all ride height settings
• Lowering Range: 60mm–100mm below OEM ride height
• Front and Rear: Reuses OEM top mounts for straightforward installation
• Anodized and Powder Coated Mounts — Built to resist corrosion and withstand daily use
• Anti-Rust Coating on Strut Threads — Protects adjustment threads for long-term reliability
• 1-Year Manufacturer's Warranty — Fully serviceable in the USA

Whether you're building a focused street machine or need a suspension setup that can handle the occasional autocross or track day, the D2 Racing D-MI-03 RS Coilover Kit delivers proven performance at an accessible price point.
