BC Racing RM-MA Coilovers – Mitsubishi Colt CZT/Ralliart

BC Racing RM-MA Series Coilovers

The BC Racing RM-MA Series coilovers are engineered to deliver an excellent balance of performance, precision, and handling, making them an ideal choice for spirited road driving, track days, and motorsport applications.

Designed and extensively tested for each vehicle application, the RM-MA kit combines carefully selected spring rates and optimized damping characteristics with advanced inverted damper technology to provide responsive handling under demanding driving conditions.

Advanced Inverted Monotube Damper Technology

The RM Series features an inverted monotube damper design with a large 42mm shaft, providing increased structural rigidity and reduced unsprung weight for improved suspension response.

By positioning the oil and gas reservoir away from the wheel hub, BC Racing reduces heat transfer from the braking system, helping maintain consistent damping performance under sustained loads. The inverted design also improves resistance to lateral forces and suspension flex, resulting in more precise and predictable handling.
