Nitron Racing - BMW E81/ E82/ E87 Non 1M (04-13) NTR R3 Suspension Kit

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.

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.

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.

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.

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.

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.

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.

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.
