Nitron NTR R3 Coilover BMW F80 M3 (2014–2018)

Ultimate Suspension Control for Road and Track

The Nitron NTR R3 Coilover Kit is a motorsport-proven suspension upgrade for the BMW F80 M3, engineered for drivers who want the highest level of damping control, chassis feedback and adjustability. Designed for serious track day, competition and advanced performance road builds, the NTR R3 gives the F80 platform the precision and composure needed for repeated high-load driving.

Unlike simpler coilover systems, 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 tyre choice, circuit conditions, driving style and vehicle setup, giving greater control over kerb response, braking stability, corner entry and mid-corner balance.

Optional Quick-Connect Dry Break Fittings (+£890)

For advanced builds, Nitron offer an upgrade to quick-connect dry break fittings that allow the remote reservoirs to be relocated into the cabin or engine bay without any fluid loss. Ideal for serious users who frequently adjust settings.

Benefits include:

• Convenient access for quick damping changes

• Improved protection from heat, road debris, or impact

• Cleaner installation in race or track-prepped builds

• Enhanced thermal performance when mounted away from heat sourcesThis upgrade is highly recommended for competition cars or any application where setup tuning speed matters. Contact us before ordering to include this option.

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

For the F80 M3, the NTR R3 is available in either True Rear or Divorced Rear configuration. The True Rear setup combines the spring and damper into one coilover unit for reduced weight and greater tuning flexibility, while the Divorced Rear setup retains the factory-style separate rear spring and damper layout.

Nitron supplies the kit with carefully developed Fast Road or Track spring rate options. The Fast Road setup is suited to high-performance road use with occasional track days, while the Track setup offers increased stiffness, reduced roll and sharper feedback for more focused circuit driving. Custom spring rates, spring lengths and damper lengths are also available on request.

Built around a high-pressure monotube damper layout, large-diameter pistons, lightweight corrosion-resistant materials and titanium hard-anodised finishes, the NTR R3 is designed to deliver consistent, fade-resistant performance under demanding conditions. Each kit is built to order by Nitron in the UK and is fully serviceable, rebuildable and upgradeable for long-term use.

Suitable for BMW F80 M3 models produced from 2014-2018, this is a serious suspension solution for owners looking to maximise grip, confidence and adjustability from the F80 chassis.
