BMW 3 SERIES SEDAN (3-BOLT) AWD F30 (12-19) BC Racing RM Series MA Coilovers | 6/9kg.mm

BC Racing RM Series MA Coilovers are purpose-built suspension components engineered specifically for the BMW 3 SERIES SEDAN (3-BOLT) AWD F30 (12-19), delivering precise handling dynamics with a 6/9kg.mm spring rate configuration. These coilovers feature inverted shock technology with a camber pillowball top mount at the front, complemented by flexible rear mounting options including rubber or no top mount, allowing drivers to customise their suspension setup to suit their driving requirements. Whether you're focused on track performance or refined road handling, the BC Racing RM Series MA provides the adjustability and quality engineering expected from a leading suspension manufacturer.

BC Racing RM Series Coilovers

The BC Racing RM Series features high-quality damping-adjustable monotube inverted dampers at the front, or front and rear depending on the vehicle. The RM offers the majority of the features of the BR Series with the additional benefit of the inverted damper unit — a design that reduces unsprung weight and moves vital damper fluid away from detrimental heat sources to prevent the overheating that causes damper fade under extreme track use.

Key Features

• Digressive piston and damping curve
• Inverted monotube damper bodies
• Reduced unsprung weight
• 30-way adjustable damping
• Ride height adjustment separate to spring preload
• Camber adjustable top mounts (depending on model)
• Pillowball upper mount (depending on model)
• Bearing mounted upper front spring platform (depending on model)
• Tapered bottom mount locking collar to prevent collar working loose
• Custom spring rates available (depending on model)
• All spare parts available with low lead times
• Dust boot to protect damper seals
• 1 year manufacturer warranty

Reduced Unsprung Weight

Unsprung weight is reduced by moving the oil and gas reservoir away from the hub and attaching it to the shell. A lighter wheel and hub assembly responds more readily to road bumps, maintaining greater grip over imperfect surfaces. High unsprung weight can lead to wheel hop on bumpy ground, reducing both ride quality and ultimate handling.

Reduced Heat Transfer to Damper Fluid

Hard-driven cars generate significant heat within the braking system, conducted through the hub into the damper unit. By inverting the damper, the oil and gas reservoir is moved away from the hub, reducing conducted heat reaching the fluid. Keeping oil and gas temperatures lower maintains consistent damping rates — allowing you to corner faster for longer.

Reduced Flex

The large 42mm damper rod combined with the inverted design gives the RM units significantly greater strength and resistance to side loadings during hard cornering, resulting in more consistent steering geometry and more predictable, responsive handling.

The MA configuration is supplied with inverted dampers and aluminium camber adjustable pillowball top mounts on the front (where available), and upright dampers with aluminium rear top mounts with rubber centres or no rear top mounts depending on the application.
