Nitron NTR R3 Coilovers – BMW G80 M3 2021+

Ultimate Suspension Control for Road and Track – BMW G80 M3

The Nitron NTR R3 Coilover Kit is a motorsport-developed suspension system for G80 M3 owners who demand uncompromising control, feedback, and adjustability. Whether carving B-roads or chasing lap times, the R3 delivers precision handling and predictable performance.

3-Way Damping Adjustment

The R3 offers three-way independent damping control – rebound, fast compression, and slow compression – allowing you to fine-tune chassis balance, grip, and ride quality. Available with remote or piggyback reservoir layouts for optimal fitment and performance.

Key features:

• Separate rebound, fast compression, and slow compression control

• Large-diameter piston for fade-free consistency

• True or divorced rear spring configuration

• Bi-Axis hose fittings on remote reservoir kits

• Fully serviceable and rebuildable

• Titanium and hard-anodised components

• Hand-built to order in the UK

Spring Rate Options – Tuned by Nitron for the BMW G80 M3

Nitron’s recommended rates are engineered for the G80 chassis, balancing comfort with performance.

Fast Road Setup – Ideal for spirited road use with occasional trackdays:

Track Setup – Stiffer rates for track and high-performance builds:

Note: True rear coilover rates appear lower due to motion ratios – overall stiffness is equivalent.

Custom spring rates, lengths, and damper specs are available on request.

Optional Quick-Connect Dry Break Fittings (+£895)

Upgrade to quick-connect dry break fittings for remote reservoirs, allowing relocation (e.g. cabin or engine bay) without fluid loss. Benefits include:

• Faster, easier damping adjustments

• Cleaner, motorsport-style installation

• Improved thermal performance by isolating reservoirs

• Protection from heat, dirt, and debris

Race-Grade Construction and Materials

Nitron’s monotube design with large pistons and precision internals ensures consistent damping even under extreme loads. Lightweight, corrosion-resistant materials with hard-anodised and titanium finishes make them ideal for year-round use.

Bi-Axis Hose Fittings (Remote Reservoir Kits Only)

Patented Bi-Axis hose fittings allow flexible reservoir mounting, simplifying installation in tight spaces and improving long-term reliability.
