Description
Nitron NTR R3 coilovers for BMW E90 and E92 M3 provide independent rebound, low-speed compression and high-speed compression adjustment. This listing covers the M3 saloon/coupe application, not a universal E9X suspension package.
Fitment, mounts and rear layout
Confirm E90 saloon or E92 coupe specification, factory electronic damping and any existing conversion. E93 convertible and non-M3 applications require separate checks. Agree the electronic-damper integration or cancellation solution rather than assuming manual R3 dampers retain factory adjustment.
The existing application specification describes adjustable front camber/caster top mounts with spherical bearings. Confirm the actual supplied mounts and rear spring arrangement before ordering. Spherical or rigid mounts can transmit more noise and vibration than rubber mounts, which matters on a road-driven M3.
Develop the damping setup
Independent compression and rebound controls are useful with a defined tyre, spring and alignment baseline. Reservoir placement and hose clearance must suit the installation. A particular lowering figure cannot be guaranteed without checking the starting ride height, travel and selected build.
Nitron R3 dampers are serviceable. Additional spring choices or other hardware should be agreed as part of the order, not inferred from a generic image.
Compare R1 and complete the installation
The E90/E92 M3 NTR R1 is the combined-adjustment alternative. A non-M3 uses the separate non-M3 R3 application.
Use professional fitting, inspect mounts and adjacent joints, and complete a measured alignment. Confirm build timing before booking work. Browse the Nitron range.
Plan the E90/E92 M3 suspension setup
Before choosing the build, provide your body style, factory EDC specification, tyre size and type, intended road/track use, and current top mounts. Agree the spring specification and rear spring arrangement with the kit supplier, then record ride height and alignment as the starting point for damping adjustments.
With R3, make one adjustment at a time and record the setting, tyre pressures and conditions. High- and low-speed compression refer to damper movement speed, rather than the speed of the car.
If you are also considering front top mounts, read our Millway E92 M3 camber plate fitment guide. A shared E92 application does not confirm compatibility with a particular Nitron build. Explore the wider BMW E9X M3 track-day parts range when planning the rest of the car.

Nitron FAQ's
Here's some frequently asked questions about Nitron Suspension
Which Nitron suspension kit is best for road use?
For most road and fast road cars, we’d usually look at the Nitron RoadSport or NTR R1 kits. The RoadSport kit is designed to balance performance, comfort and reliability, while still keeping ride quality sensible for daily driving. The NTR R1 is a step up if you want more adjustment and a more focused road/track setup.
What is the difference between Nitron RoadSport, R1 and R3 coilovers?
The Nitron RoadSport kit is the most road-focused option, using OE top mounts and following the OE rear suspension type, making it a good choice for comfort and everyday use. The NTR R1 gives you easy-to-use 2-way combined damping control and is built for strong road and track performance. The NTR R3 is the more serious option, with independent 3-way damping adjustment, giving separate control of rebound, high-speed compression and low-speed compression for drivers who want to fine-tune the car properly.
Are Nitron coilovers suitable for track use?
Yes, Nitron suspension is very well suited to track use, but the right kit depends on how serious the car is. The NTR R1 is a strong option for fast road and track day use, while the NTR R3 is better suited to more focused builds where you want a larger range of adjustment and more detailed control over the car’s behaviour.
Are Nitron coilovers rebuildable or serviceable?
Yes, one of the big benefits of Nitron suspension is that the shocks are designed to be fully serviceable. Nitron state that their modular shock design allows products to be serviced, with critical components, fluids, gas, seals and bushes replaced to return the product to an “as new” technical condition.
What does Nitron R3 adjustment actually do?
Nitron R3 coilovers give independent 3-way damping adjustment. That means you can adjust rebound separately from high-speed and low-speed compression. In simple terms, it gives much more control over how the car reacts under braking, cornering, kerb strikes, bumps and weight transfer. For most normal road cars it may be more than needed, but for track-focused cars it’s a proper step up.
Do Nitron coilovers need setting up after fitting?
Yes, definitely. Nitron suspension should be installed properly, and after fitting we’d always recommend setting ride height sensibly, checking preload where applicable and carrying out a full alignment. For more serious road and track cars, corner weighting and proper geometry setup are well worth doing so you actually get the benefit from the suspension rather than just fitting it and leaving it.
What is the difference between a divorced rear and a true rear coilover setup?
On some vehicles, the factory rear suspension uses a divorced layout, where the spring and damper are mounted separately. A true rear coilover setup moves the spring onto the damper body, creating a coilover-style rear arrangement. The best option depends on the vehicle, how it’s used and what the suspension kit is designed for. For most road and fast road builds, we’d normally stick with the layout recommended by Nitron for that specific application.
Should I choose a divorced rear or true rear coilover setup?
If the car is mainly used on the road, a divorced rear setup is often the more suitable choice, especially where it follows the original suspension design. A true rear coilover setup can offer more adjustment and can be useful on certain track-focused builds, but it is not always the best option for every car. We’d always recommend choosing the correct Nitron kit for the vehicle rather than assuming true rear is automatically better.
