Nitron NTR R3 Coilovers BMW G80 M3 2021+

Ultimate Suspension Control for Road and Track

The Nitron NTR R3 Coilover Kit is a motorsport-developed suspension upgrade for the BMW G80 M3, designed for drivers who want maximum damping control, chassis feedback and setup flexibility. Built for serious fast road, track day and competition use, the NTR R3 gives the G80 platform the precision and composure needed to perform consistently under repeated high-load driving.

The system offers fully independent 3-way damping adjustment, giving separate control over rebound, fast compression and slow compression. This allows the suspension to be fine-tuned around road surface, tyre choice, circuit conditions and driver preference, helping optimise grip, braking stability, kerb response, corner entry and mid-corner balance.

The kit is available with either remote reservoir or piggyback reservoir layouts depending on specification. Remote reservoir kits include Bi-Axis hose fittings for flexible and reliable mounting, while optional quick-connect dry break fittings allow the reservoirs to be relocated into the cabin or engine bay without fluid loss. This is especially useful for serious track cars where fast adjustment access, reservoir protection and thermal isolation are important.

For the G80 M3, the NTR R3 can be specified in either True Rear or Divorced Rear configuration. The True Rear setup combines the spring and damper into a single coilover unit for reduced weight, sharper response and greater setup flexibility, while the Divorced Rear option retains the OEM-style separate spring and damper layout.

Nitron supplies the kit with Fast Road or Track spring rate options, with custom spring rates, spring lengths and damper specifications available on request. This allows the setup to be tailored around road use, track use, tyre choice and the overall level of build.

Built around a high-performance monotube damper design, large-diameter pistons and lightweight corrosion-resistant components with hard-anodised and titanium finishes, the NTR R3 is engineered for fade-resistant damping, durability and long-term serviceability. Each kit is hand-built to order by Nitron in the UK and is fully serviceable and rebuildable.

Suitable for BMW G80 M3 applications, this is a serious suspension solution for owners looking to maximise control, confidence and repeatable performance from the modern G8X chassis.
