BC Racing RM Series Coilovers – BMW F80 M3 / F82 M4 3-Bolt Top Mount (2018)

The BC Racing RM Series Coilovers for the BMW F80 M3 and F82 M4 with the 3-bolt front top mount are a high-performance suspension upgrade designed for drivers looking for increased rigidity, reduced unsprung mass and sharper chassis response during demanding fast-road and track use.

The RM Series uses an inverted monotube damper design, helping increase structural rigidity while reducing the mass of moving suspension components. Combined with 30-way damping adjustment and adjustable ride height, it provides a more specialised suspension setup than the BR or DS Series.

Why choose BC Racing RM Series for your F80 M3 or F82 M4?

The F80 M3 and F82 M4 are highly capable performance platforms, and the RM Series is aimed at owners looking for a more focused suspension setup for regular track and demanding fast-road use.

The inverted damper design can improve rigidity and suspension response during rapid direction changes and high-load cornering, while the 30-way damping adjustment allows the setup to be tailored around tyre choice, alignment and intended use.

This makes the RM Series particularly well suited to F8X builds where chassis precision and track performance are priorities.

Inverted Damper Technology

The defining feature of the RM Series is its inverted monotube damper design.

Unlike a conventional damper, the inverted layout places more of the damper assembly towards the chassis. This can reduce unsprung mass while increasing rigidity within the suspension assembly.

The design is particularly useful during demanding driving, where repeated suspension movement and higher lateral loads place greater stress on the dampers.

For track-focused F80 M3 and F82 M4 builds, this makes the RM Series a strong option for drivers looking for a more specialised suspension setup.

Important 3-Bolt Top Mount Fitment

This kit is intended specifically for F80 M3 and F82 M4 models using the 3-bolt front top mount configuration.

BMW used different front top-mount arrangements across F8X applications, so the mounting pattern should be confirmed before ordering.

A 3-bolt application should not be assumed to be interchangeable with a different top-mount configuration.

If you're unsure which version your vehicle uses, check the front strut top mount or contact us before ordering and we can help identify the correct kit.

BMW F80 M3 / F82 M4 Track Suspension

The RM Series gives F80 M3 and F82 M4 owners a highly adjustable platform for developing the car's handling performance.

The inverted damper design helps increase rigidity and reduce unsprung mass, while adjustable damping allows the suspension to be tailored around tyres, alignment and driving style.

The RM Series can also work alongside other chassis upgrades such as:

• Performance tyres
• Adjustable suspension arms
• Uprated anti-roll bars
• Polyurethane or solid bushes
• Chassis braces
• More aggressive alignment settings

For cars that regularly see track use, the RM Series provides greater scope to develop the suspension around spring rates, corner weights and geometry.

30-Way Damping Adjustment

The RM Series provides 30 levels of damping adjustment, allowing the suspension response to be tailored to different driving conditions.

Softer settings can provide greater compliance for road use, while firmer settings can increase chassis control during spirited driving and track use.

This adjustment also allows the suspension to be refined as tyres, alignment or other chassis modifications change.

Adjustable Ride Height

The BC Racing RM Series allows the ride height of your F80 M3 or F82 M4 to be adjusted to suit both appearance and performance requirements.

For road-driven cars, this makes it possible to reduce arch gap and achieve a lower, more purposeful stance.

For track-focused setups, ride height should be considered alongside suspension travel, geometry, alignment and corner weighting rather than simply lowering the vehicle as far as possible.

RM Series Maintenance

The increased performance of the RM Series does come with additional maintenance compared with more conventional coilover designs.

The inverted damper assemblies should be kept clean and inspected regularly, particularly on cars exposed to road grime, water and frequent track use.

Relevant moving and mating surfaces should also be maintained in line with BC Racing's recommendations to help reduce unwanted noise or wear.

If your F80 M3 or F82 M4 is primarily used on the road and low maintenance is a priority, the BR or DS Series may be the more suitable option.

Choosing Your Spring Rate

The RM Series is available with application-specific spring rates, with alternative and custom spring-rate options available depending on your requirements.

The ideal setup will depend on:

• Road or track use
• Vehicle weight
• Tyre type and grip level
• Alignment
• Anti-roll bars
• Other suspension modifications
• Driver preference

For track-focused builds, spring rates should be considered alongside damping, alignment and the rest of the chassis setup rather than selected independently.

If you're unsure which RM Series specification is best suited to your F80 M3 or F82 M4, contact us before ordering and we can help you choose the right setup.
