Upgrade the suspension of your BMW 1 Series E81 with BC Racing RM Series Coilovers, developed for drivers looking for a more performance-focused suspension setup for fast-road, trackday and motorsport use.
The RM Series provides increased chassis control and adjustability while allowing the suspension setup to be tailored around the intended use of the car.
For this application, the standard spring rate specification is 5.5kg/mm front and 8kg/mm rear.
Standard Spring Rates
Standard spring rates:
- Front: 5.5kg/mm

This provides a balanced starting point for drivers wanting improved suspension control while retaining usability for mixed road and performance driving.
Alternative spring rates may also be available for more specialised setups.

The exact top mount arrangement depends on the vehicle and selected kit configuration.

Designed for Performance Use
The RM Series is particularly well suited to:
- Fast-road driving
- Track days
- Clubsport builds
- Performance-focused road cars
- Cars running higher-grip tyres
- Drivers wanting increased suspension control
Adjustable Ride Height
BC Racing RM Series Coilovers allow ride height to be adjusted to suit your preferred stance and chassis setup.
This gives greater control over:
- Vehicle height
- Wheel fitment
- Arch clearance

Ride height should always be set with sufficient suspension travel and clearance for safe operation.
Adjustable Damping
The RM Series provides damping adjustment, allowing the suspension response to be tailored around:
- Road conditions
- Tyre choice
- Driver preference
- Vehicle setup
- Track use
This gives considerably more flexibility than a fixed spring and damper arrangement.
Improved Chassis Control
A properly configured RM Series setup can help improve:
- Body control
- Steering response
- Cornering stability
- Weight transfer management
- Brake dive control
- Overall chassis confidence
The ability to tailor damping, ride height and spring rates makes the RM Series particularly suitable for more focused BMW builds.
