Precision Suspension for Road and Track

Upgrade your BMW E9X M3 with the Nitron NTR R1 Coilover Kit – a premium, hand-built suspension system engineered for high-performance road driving and serious track use.

Developed from Nitron’s competition-level R3 system, the R1 offers 1-way combined damping adjustment for both bump and rebound. This compact, user-friendly design delivers impressive handling improvements, sharper steering response, and enhanced confidence on track – without the complexity of remote reservoirs.


Key Features of the Nitron NTR R1 Kit

  • 1-way damping adjustment (bump and rebound combined)

  • True or Divorced rear spring configuration for E9X chassis

  • Choice of spring rates: Fast Road or Track

  • Ultra-low friction internals to minimise fade

  • Titanium and hard-anodised components for long-term durability

  • Lightweight, corrosion-resistant construction

  • Fully serviceable and rebuildable

  • Hand-assembled in the UK to order


Spring Rate Options – Tuned by Nitron for the BMW E9X M3

Each Nitron NTR R1 kit is supplied with carefully selected spring rates and damper lengths based on extensive development and testing. Nitron’s team take into account the unique characteristics of the E9X M3 to offer a setup that works exceptionally well out of the box.

Two options are available to suit different use cases:

Fast Road Setup

Ideal for high-performance road driving and occasional track use. Offers excellent control with a compliant ride.

  • Front: 120 N/mm

  • Rear (Divorced): 120 N/mm

  • Rear (True Coilover): Approx. 62 N/mm equivalent*

Track Setup

Designed for drivers who want sharper handling and improved chassis control at higher speeds or during trackdays.

  • Front: 140 N/mm

  • Rear (Divorced): 140 N/mm

  • Rear (True Coilover): Approx. 70 N/mm equivalent

    True rear spring rates appear lower due to different mounting ratios and spring positions – overall stiffness is comparable.


Custom Options Available

Custom spring rates, spring lengths, and damper lengths can be requested to suit unique builds or preferences. Contact us before ordering and we’ll work with Nitron to tailor the kit to your exact needs.


True vs Divorced Rear – What’s the Difference?

True Rear Setup

Combines the spring and damper into a single coilover unit, mounted together. This is often preferred for track-focused setups due to its simplicity, reduced weight, and improved response.

Divorced Rear Setup

Retains the factory-style layout with separate spring and damper. This option maintains the original suspension geometry and is a straightforward fitment for those who prefer the OEM configuration.

Which Should You Choose?

Both configurations offer excellent performance.

  • Choose True Rear for maximum handling sharpness and adjustability.

  • Choose Divorced Rear if you want to retain the OEM layout or prefer a more traditional installation approach.


Race-Bred Engineering for the BMW E9X M3

The NTR R1 shares its core architecture with Nitron’s full competition R3 kit. This ensures a level of damping performance, build quality, and longevity far beyond typical aftermarket suspension.

Low-friction internals and a monotube design ensure consistent performance even under repeated high-load use. Whether you're pushing hard on track or chasing precision on fast A-roads, the R1 is built to deliver.


Built to Order in the UK – Customised for You

Every NTR R1 kit is hand-built to your spec at Nitron’s UK facility. Choose your spring rate and rear layout at checkout and we’ll handle the rest.

Lead time is typically 2–3 weeks. For the most accurate estimate, contact us directly and we’ll check with Nitron.
