BC Racing ZX Series Coilovers – BMW E92 M3 without EDC (2008–2013)
The BC Racing ZX Series Coilovers for the BMW E92 M3 without Electronic Damper Control are an advanced, track-focused suspension system designed for drivers looking for maximum damping adjustability, external reservoirs and detailed chassis control.
The ZX Series uses 3-way adjustable damping, allowing low-speed compression, high-speed compression and rebound to be tuned independently. Combined with external reservoirs and adjustable ride height, it provides a much greater level of setup control than the BR, DS, RM or ER Series.
Why choose BC Racing ZX Series for your E92 M3 without EDC?
The BMW E92 M3 is a highly capable performance platform, and the ZX Series is aimed at owners building a serious fast-road, track or competition-focused car.
Independent control over low-speed compression, high-speed compression and rebound allows the suspension to be developed around tyre choice, spring rates, alignment, vehicle weight and circuit conditions.
Because this application is for vehicles without factory EDC, there is no electronic damping system to disable when fitting the coilovers.

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
Low-speed compression can be used to influence slower chassis movements such as body roll, pitch, braking dive and weight transfer.
High-speed compression controls how the suspension responds to faster damper movements caused by bumps, kerbs and sharper surface changes.
Rebound then controls how quickly the suspension extends again after compression.
This gives experienced drivers and suspension specialists a much wider range of setup possibilities than a conventional single- or 2-way adjustable coilover.
External Reservoirs
The ZX Series uses external reservoirs as part of its advanced damper design.
The additional oil capacity helps manage temperatures generated during sustained hard driving and repeated suspension movement.
For E92 M3s that regularly see longer track sessions, this can help maintain more consistent damping behaviour as temperatures rise.
Non-EDC Application
This kit is intended specifically for E92 M3 models that were not equipped with factory Electronic Damper Control.
Because the vehicle uses conventional dampers from the factory, there is no EDC functionality to disable when installing the BC Racing ZX Series.
If you're unsure whether your car has EDC, check the vehicle specification before ordering or contact us and we can help confirm the correct application.
BMW E92 M3 Track Suspension
The ZX Series provides a highly adjustable platform for developing the E92 M3 chassis.
Its 3-way damping control allows the suspension to be configured around upgrades such as:
- Performance tyres
- Adjustable suspension arms
- Uprated anti-roll bars
- Polyurethane or solid bushes
- Chassis reinforcement
- More aggressive alignment settings
For dedicated track builds, professional alignment and corner weighting can help make full use of the available adjustment.
Adjustable Ride Height
The BC Racing ZX Series allows the ride height of your E92 M3 to be tailored around both performance and appearance requirements.
For fast-road cars, this allows the vehicle to sit lower with a more purposeful stance.
For track-focused cars, ride height should be considered alongside suspension geometry, available damper travel, alignment and corner weighting rather than simply lowering the car as far as possible.
Choosing Your Spring Rate
Spring-rate selection is particularly important on a highly adjustable suspension system such as the ZX Series.
The ideal setup will depend on:
- Vehicle weight
- Tyre compound and width
- Road or track use
- Alignment
- Anti-roll bars
- Other chassis modifications
- Circuit characteristics
- Driver preference
For serious track builds, spring rates and damper valving should ideally be considered together as part of the complete suspension setup.
If you're unsure which ZX Series specification is best suited to your E92 M3, contact us before ordering and we can help you choose an appropriate setup.
ER Series vs ZX Series
The ER Series provides independent compression and rebound adjustment with external reservoirs.
The ZX Series takes adjustability further by separating low-speed compression, high-speed compression and rebound.
This makes the ZX Series the more advanced option for drivers looking to fine-tune chassis behaviour around specific tyres, circuits and track conditions.
Maintenance & Servicing
The ZX Series is a rebuildable high-performance suspension system designed for demanding use.
The dampers, reservoirs, hoses, adjusters and mounting hardware should be kept clean and inspected regularly, particularly on vehicles used frequently on track.
Following BC Racing's recommended servicing procedures will help maintain consistent damping performance and maximise the service life of the suspension.
E92 M3 Non-EDC Compatibility
This BC Racing ZX Series kit is intended for the BMW E92 M3 produced between 2008 and 2013 without factory EDC.
Please confirm your exact vehicle specification before ordering, particularly if the car has had previous suspension modifications.
If you're unsure whether this is the correct kit for your M3, contact us and we'll help you identify the appropriate application.
