I-121-RM - BC Racing RM Series Coilover Suspension Kit - E46 M3 Convertible
BC Racing RM Series Coilover Suspension Kit - E46 M3 Convertible
For the E46 M3 Convertible owner who demands uncompromised feedback during spirited driving or track sessions, the BC Racing RM Series offers a professional-grade motorsport approach. By moving the fluid reservoir away from the wheel hub and brake components, the RM Series manages heat more effectively, preventing damper fade during prolonged high-speed sessions. The inclusion of front pillowball camber plates replaces compliant factory rubber bushings, providing direct and unmediated steering feel. Because convertibles often require higher roll stiffness to compensate for chassis flex, the RM Series' default 12kg rear spring rate provides the stability needed to keep the E46 M3 planted and responsive through tight technical sections.
Key Features:
Reduced Damper Fade: Inverted layout keeps oil temperature more stable by increasing distance from hot brake components.
Camber Adjustable Top Mounts: Precision-engineered aluminum plates allow for aggressive alignment specs to maximize front-end grip.
Patented Concave Locking Ring: Unique design ensures that once ride height is set, the lower mounts remain locked securely against vibration.
Linear Piston Architecture: Provides a predictable and consistent damping feel for better driver confidence at the limit.
Fully Rebuildable: Every component is individual and replaceable, ensuring the long-term serviceability of the system.
Specifications:
Vehicle Fitment: 2000–2006 BMW M3 (E46) Convertible / Coupe.
Spring Rates (Default): Front: 8 kg/mm | Rear: 12 kg/mm.
Optional Upgrades: Compatible with custom spring rates and Swift Springs (+2kg/-2kg range on standard valving).
Finish: Black chrome-plated steel bodies for maximum corrosion resistance.
Warranty: 2-Year limited warranty against manufacturer's defects.
