BC Racing DS Series Coilovers – BMW 1 Series F40 FWD
The BC Racing DS Series Coilovers for the BMW 1 Series F40 FWD are a performance-focused suspension upgrade designed to improve chassis control, handling response and ride-height adjustability for fast-road and track use.
The DS Series uses digressive damping technology, providing increased damping force during lower-speed suspension movements while allowing the suspension to respond more freely to larger bumps, kerbs and sharper surface changes.
Why choose BC Racing DS Series for your BMW F40?
The BMW F40 1 Series uses a front-wheel-drive-based platform, giving it different chassis characteristics from the earlier rear-wheel-drive F20 generation.
The BC Racing DS Series gives you greater control over the F40's suspension response, with adjustable damping and ride height allowing the setup to be tailored around your driving style, tyre choice and other chassis modifications.
The digressive damper design is intended to provide strong control during braking, acceleration and cornering, while retaining the ability for the suspension to react effectively to rougher road surfaces.
For F40 owners looking for a sharper and more performance-focused setup than the BR Series, the DS Series is a strong option.

BMW F40 Suspension Upgrade
The BC Racing DS Series gives F40 owners significantly more control over their suspension setup than the standard dampers and springs.
Ride height and damping can be adjusted to complement other handling upgrades such as performance tyres, uprated anti-roll bars, polyurethane bushes, strut braces and performance alignment settings.
For a fast-road F40, the DS Series can provide sharper body control and steering response while retaining a usable level of suspension compliance.
For cars that see regular track use, the additional damping characteristics provide greater scope to develop the setup around tyre choice, alignment and driving style.
After fitting coilovers or making significant ride-height changes, we recommend having the vehicle professionally aligned.
Digressive Damping Technology
The defining feature of the DS Series is its digressive damping design.
The damper provides increased control during lower-speed suspension movements, such as body roll, pitch, braking dive and weight transfer during acceleration and cornering.
As damper shaft speed increases, the damping curve becomes less aggressive, allowing the suspension to move more freely over larger bumps, kerbs and surface changes.
This can provide a useful balance between chassis control and maintaining mechanical grip, particularly during demanding fast-road and track driving.
30-Way Damping Adjustment
The DS Series provides 30 levels of damping adjustment, allowing you to fine-tune the suspension response to suit your driving style and conditions.
Softer settings can provide greater compliance for everyday road use, while firmer settings can increase chassis control for spirited driving and track use.
This also gives you the ability to develop the suspension around changes to tyres, alignment and other chassis modifications.
Adjustable Ride Height
Ride height can be adjusted independently of spring preload, allowing you to lower the F40 without simply increasing spring compression.
This gives you greater control over both the stance and suspension setup of the car.
For road-driven F40s, this allows you to reduce arch gap while maintaining a properly configured suspension setup.
For more performance-focused builds, ride height should ideally be considered alongside alignment and suspension geometry.
Choosing Your Spring Rate
The DS Series is available with application-specific spring rates, with alternative and custom spring-rate options available depending on the selected specification.
The ideal setup will depend on your exact F40 model, tyre choice, vehicle weight, suspension modifications and intended use.
For predominantly road-driven cars, a more compliant setup will generally provide the best balance between ride quality and handling. More aggressive spring rates can be considered for fast-road and track-focused builds.
If you're unsure which specification is best suited to your F40, contact us before ordering and we can help you choose the right setup.
F40 FWD Compatibility
This kit is designed for applicable front-wheel-drive BMW 1 Series F40 models.
The F40 range includes different engine, drivetrain and suspension configurations, so it is important to confirm your exact vehicle specification before ordering.
If you have an xDrive model, make sure you select the correct BC Racing application rather than the FWD kit.
What's Included?
The BC Racing DS Series is supplied as a complete coilover suspension kit for the applicable BMW F40 FWD application, including the vehicle-specific dampers, springs and relevant adjustable components.
Exact top-mount and spring-rate specifications can vary depending on the selected configuration, so please check your chosen kit before ordering.
