BC Racing ZX Series Coilovers – BMW E36 M3
The BC Racing ZX Series Coilovers for the BMW E36 M3 are an advanced, track-focused suspension upgrade designed for drivers looking for maximum damping control and a highly developed chassis setup for demanding circuit use.
The ZX Series is BC Racing's 3-way adjustable coilover platform, combining independent low-speed compression, high-speed compression and rebound adjustment with external reservoirs. This provides significantly greater control over damper behaviour than the BR, DS or RM Series.
Why choose BC Racing ZX Series for your E36 M3?
The BMW E36 M3 is an excellent platform for track and competition use thanks to its balanced rear-wheel-drive chassis and relatively simple suspension layout.
The ZX Series is aimed at owners who want to develop the suspension around specific tyres, spring rates, alignment settings and circuit conditions.
With independent adjustment of low-speed compression, high-speed compression and rebound, the ZX Series allows individual areas of the car's behaviour to be tuned separately rather than relying on a single combined damping setting.
This makes it particularly well suited to dedicated track cars, competition builds and highly developed fast-road E36 M3s.

BMW E36 M3 Track Suspension
The ZX Series provides a highly adjustable platform for developing the chassis of the E36 M3.
Low-speed compression can be used to influence chassis movements such as roll, pitch and weight transfer, while high-speed compression allows the suspension response to bumps, kerbs and sharper surface changes to be adjusted separately.
Rebound adjustment then controls how quickly the suspension extends after compression.
This level of control allows the setup to be developed around performance tyres, alignment settings, spring rates and other chassis modifications.
For track-focused builds, the ZX Series can also work alongside adjustable suspension arms, uprated bushes, anti-roll bars and more aggressive geometry settings.
3-Way Damping Adjustment
The defining feature of the ZX Series is its independent 3-way damping adjustment.
The suspension allows separate adjustment of:
- Low-speed compression
- High-speed compression
- Rebound
Separating these three areas provides a much wider range of setup possibilities than a conventional single- or 2-way adjustable coilover.
For experienced drivers and suspension specialists, this allows the E36 M3 to be tuned more precisely around specific circuits, tyre characteristics and driving conditions.
External Reservoirs
The ZX Series uses external reservoirs to increase damper oil capacity and improve heat management.
During prolonged track use, repeated suspension movement generates heat within the damper. Increased oil capacity and external reservoirs help manage temperature and maintain more consistent damping behaviour throughout a session.
This makes the ZX Series particularly well suited to E36 M3 builds that regularly see demanding circuit use.
Adjustable Ride Height
Ride height can be adjusted to suit both appearance and performance requirements.
For fast-road builds, this allows the E36 M3 to achieve a lower and more purposeful stance while maintaining a properly configured suspension setup.
For dedicated track cars, ride height should be considered alongside suspension geometry, corner weighting and alignment rather than simply lowering the vehicle as far as possible.
Choosing Your Spring Rate
The ZX Series can be configured with application-specific or custom spring rates depending on the intended use of the vehicle.
The ideal setup will depend on tyre choice, vehicle weight, aerodynamic load, suspension geometry, alignment and circuit use.
For a dedicated track car, spring rate and damper valving should ideally be considered together rather than selected independently.
If you're unsure which ZX Series specification is appropriate for your E36 M3, contact us before ordering and we can help you select a suitable setup.
Maintenance & Servicing
The ZX Series is a rebuildable high-performance suspension system designed for demanding applications.
Regular inspection and servicing are particularly important on cars that see frequent track use. The damper bodies, reservoirs, hoses, adjusters and mounting hardware should be kept clean and inspected regularly.
Following BC Racing's recommended servicing procedures will help maintain consistent damping performance and extend the service life of the suspension.
E36 M3 Compatibility
This BC Racing ZX Series kit is designed for the BMW E36 M3 application.
As E36 models can vary depending on year, market and existing suspension configuration, please confirm your exact vehicle specification before ordering.
If you're unsure whether this is the correct application, contact us and we'll help you identify the appropriate setup.
What's Included?
The BC Racing ZX Series is supplied as a complete coilover suspension kit for the applicable BMW E36 M3, including the vehicle-specific dampers, springs, external reservoirs and relevant adjustable components.
Exact top-mount, reservoir and spring-rate specifications can vary depending on the selected configuration, so please check your chosen setup before ordering.
