BC Racing RM Series Coilovers – BMW 2 Series F22 M235i RWD 5-Bolt
The BC Racing RM Series Coilovers for the BMW 2 Series F22 M235i with 5-bolt front top mounts are a high-performance suspension upgrade designed for drivers looking for increased chassis rigidity, reduced unsprung mass and greater suspension performance.
The RM Series uses an inverted monotube damper design, providing increased structural rigidity while reducing the weight of the moving suspension components. Combined with adjustable damping and ride height, the RM Series is particularly suited to fast-road and track-focused M235i builds.
Why choose BC Racing RM Series for your M235i?
The BMW F22 M235i combines rear-wheel drive with strong turbocharged performance, making chassis control particularly important when driving the car hard.
The RM Series takes the BC Racing platform further with its inverted damper design, helping improve rigidity and resistance to heat during demanding driving.
The 30-way damping adjustment allows you to fine-tune the suspension response, while independent ride-height adjustment allows you to lower the M235i without altering spring preload.
For M235i owners who regularly enjoy spirited driving, track days or other demanding use, the RM Series offers a more performance-oriented suspension platform.

BMW F22 M235i Suspension Upgrade
The BC Racing RM Series gives M235i owners a highly capable suspension platform for developing the car's handling performance.
The inverted damper design increases structural rigidity while reducing unsprung mass, helping the suspension respond effectively during rapid changes in direction and high-load cornering.
The RM Series can also be configured alongside performance tyres, uprated anti-roll bars, polyurethane bushes, adjustable suspension arms and more aggressive alignment settings.
For a fast-road M235i, the RM Series provides a highly adjustable suspension setup with a strong focus on chassis control. For cars that regularly see track use, the inverted design and improved heat management can provide additional benefits during sustained hard driving.
Inverted Damper Technology
The defining feature of the RM Series is its inverted monotube damper design.
Unlike a conventional damper, the inverted configuration places the larger damper shaft and associated components towards the chassis. This increases structural rigidity and reduces the amount of suspension mass moving with the wheel.
The design can also provide improved heat management during prolonged hard driving, making the RM Series particularly well suited to M235i models that see regular track use.
RM Series Maintenance
As a high-performance inverted coilover system, the RM Series requires appropriate inspection and maintenance to maintain its performance.
The inverted damper design uses a damper cartridge within the outer body, and the relevant mating surfaces should be kept correctly lubricated and inspected periodically. This is particularly important on vehicles exposed to road grime, water and frequent track use.
If your M235i is primarily an everyday road car and minimal maintenance is a priority, the BR or DS Series may be a more suitable choice. The RM Series is aimed at drivers who can make use of its additional performance characteristics.
5-Bolt Top Mount Compatibility
This BC Racing kit is specifically for the BMW F22 M235i using the 5-bolt front top mount configuration.
The F22 platform uses different suspension configurations across certain models and specifications, so it is important to confirm your vehicle's exact fitment before ordering.
The 5-bolt application is different from 3-bolt F22 applications and the two configurations should not be treated as interchangeable.
If you're unsure whether your M235i uses the 5-bolt front top mount configuration, contact us before ordering and we'll help you identify the correct kit.
Choosing Your Spring Rate
The RM Series can be supplied with different spring-rate configurations depending on the application and selected specification.
The ideal spring rate depends on how your M235i is used, its existing modifications, tyre choice and your preferred balance between compliance and handling.
For fast-road and track-focused builds, higher spring rates may be appropriate depending on the rest of the vehicle's setup.
If you're unsure which spring-rate configuration is best for your M235i, contact us before ordering and we can help you select a suitable setup.
What's Included?
The BC Racing RM Series is supplied as a complete coilover suspension kit for the BMW F22 M235i 5-bolt application, including the application-specific dampers, springs and adjustable components required for installation.
Please check your vehicle's exact specification and front top-mount configuration before ordering.
