Product Description

The Nitron NTR R3 Coilover Kit is a motorsport-developed suspension upgrade for the BMW F22 M235i and M240i, designed for drivers who want maximum damping control, chassis precision and confidence on both road and track. Built for serious fast road, track day and motorsport use, the NTR R3 gives the F22 platform a major step up in response, stability and setup flexibility.

Unlike simpler suspension kits, the NTR R3 offers fully independent 3-way damping adjustment, with separate control for rebound, fast compression and slow compression. This allows the suspension to be fine-tuned around road surface, tyre choice, circuit conditions and driver preference, giving far greater control over grip, kerb response, braking stability and overall chassis balance.

The kit is available with either remote reservoir or piggyback reservoir layouts, depending on the selected specification. Remote reservoir kits include Bi-Axis hose fittings for flexible, secure hose routing, while optional quick-connect dry break fittings allow the reservoirs to be relocated into the cabin or engine bay without fluid loss for easier adjustment access and a more motorsport-focused installation.

For the F22 M235i and M240i, the NTR R3 is available in True Rear or Divorced Rear configuration. The True Rear setup combines the spring and damper into a single coilover unit for sharper response and greater setup flexibility, while the Divorced Rear option retains the OEM-style separate spring and damper layout for a more traditional installation approach.

Nitron supplies the kit with carefully selected Fast Road or Track spring rate options, with custom spring rates, spring lengths and damper lengths available on request. The Fast Road setup is ideal for spirited road driving with occasional track use, while the Track setup offers increased stiffness, reduced roll and greater control for more focused circuit driving.

Built with a high-performance monotube damper design, large-diameter pistons, titanium and hard-anodised components, the NTR R3 is engineered for consistent, fade-resistant damping under repeated high-load use. Each kit is hand-built to order by Nitron in the UK and is fully serviceable and rebuildable for long-term performance ownership.

FAQs

Will the Nitron NTR R3 kit fit my BMW F22 M235i or M240i?

Yes. This kit is designed for BMW F22 M235i and BMW F22 M240i models.

What makes the Nitron NTR R3 different from the NTR R1?

The NTR R3 offers fully independent 3-way damping adjustment, with separate control for rebound, fast compression and slow compression. This gives a wider tuning range for more serious track day, race and high-performance road use.

What does 3-way damping adjustment mean?

3-way adjustment allows rebound, fast compression and slow compression to be adjusted independently. This gives greater control over ride quality, grip, kerb response, braking stability and chassis balance.

Should I choose True Rear or Divorced Rear?

The True Rear setup combines the spring and damper into one coilover unit and is often preferred for track-focused builds. The Divorced Rear setup retains the factory-style separate spring and damper layout for a more traditional installation.

Should I choose Fast Road or Track spring rates?

The Fast Road setup is best for spirited road driving with occasional track use. The Track setup uses stiffer spring rates for increased grip, reduced roll and greater control during hard circuit driving.

What are Bi-Axis hose fittings?

Bi-Axis hose fittings are used on remote reservoir kits to allow more flexible and secure hose routing. They help reduce stress on the fittings and make installation easier in tight or complex areas.

What are quick-connect dry break fittings?

Quick-connect dry break fittings allow the remote reservoirs to be relocated into the cabin or engine bay without fluid loss. They are a useful option for race cars or serious track builds where easier access and protection are important.

Is this kit suitable for road use?

Yes, particularly when specified with the Fast Road spring rates. However, the NTR R3 is a motorsport-focused suspension system, so ride quality will depend on the selected setup, spring rates and vehicle use.

Can the kit be customised?

Yes. Custom spring rates, spring lengths and damper lengths are available on request, allowing the kit to be tailored to specific vehicles, tyre choices and intended use.

Is the Nitron NTR R3 rebuildable?

Yes. The NTR R3 dampers are fully serviceable and rebuildable, making them a strong long-term suspension upgrade for road, track day and motorsport use.

How long does the kit take to arrive?

Each kit is hand-built to order by Nitron in the UK. Typical lead time is around 2-3 weeks, although this can vary depending on specification and availability.
