BC Racing RM Series Coilovers – Audi A3 / S3 8V Saloon (2013–2020) 54.5mm
Upgrade the suspension of your Audi A3 or S3 8V Saloon with the BC Racing RM Series coilover kit, designed for drivers wanting a more focused suspension setup for fast-road, track day and performance use.
This application is specifically for vehicles using the 54.5mm front strut diameter, so the existing suspension should be checked before ordering to confirm compatibility.
The RM Series uses an inverted monotube damper design, helping increase rigidity and improve response under hard braking, cornering and weight transfer.
Inverted Monotube Damper Design
The key feature of the BC Racing RM Series is its inverted damper construction.
This design helps increase rigidity at the wheel and reduce flex under higher loads, making it particularly well suited to more performance-focused applications where steering response, consistency and chassis control are priorities.

-
Custom specification options available
-
Designed for Audi A3 / S3 8V Saloon models with 54.5mm front struts
Spring Rate Options
Available spring-rate configurations include:
6/5kg.mm – recommended spring rate for a balance of comfort and performance
9/9kg.mm – firmer, more track-focused setup for increased chassis support and response
The 6/5kg.mm setup provides the most balanced option for road and fast-road use, improving body control and response while retaining a more compliant ride.
The 9/9kg.mm configuration is significantly firmer and better suited to drivers prioritising reduced body movement, sharper response and more demanding circuit use.
Adjustable Ride Height & Damping
The BC Racing RM Series allows ride height to be adjusted independently of spring preload, helping retain usable damper travel when lowering the vehicle.
30-way damping adjustment allows the suspension response to be fine-tuned depending on intended use, from fast-road driving through to more demanding track work.
54.5mm Front Strut Fitment
This listing is specifically for Audi A3 / S3 8V Saloon models using a 54.5mm front strut diameter.
Different 8V variants can use different front strut sizes, so the diameter should be confirmed before ordering.
If you are unsure which version your vehicle requires, please contact us with your vehicle details before placing your order.

Product Image & Specification Note
Product images are for illustration purposes only and may not show the exact specification supplied for every vehicle application.
BC Racing kits can vary depending on vehicle, spring rate, top mount configuration and other specification options. If you have any specific requirements, such as upgraded or alternative top mounts, spring rates or ride-height preferences, please contact us before ordering so we can confirm the most suitable configuration for your setup.
Fast Road & Track Performance
The RM Series is particularly suited to drivers wanting a more responsive and performance-led setup than a conventional road-focused coilover kit.
Its inverted damper construction helps improve rigidity and response under load, while the two spring-rate options allow the setup to be matched more closely to road or track-focused use.
Professional Installation Recommended
Professional installation is recommended.
A full four-wheel alignment should also be carried out after installation and once the final ride height has been set to ensure correct geometry, tyre wear and handling characteristics.
