Spring Rate Options – Tuned by Nitron for the BMW F82 M4

Spring rates for the NTR R3 system have been developed through extensive chassis testing to offer superb control, stability, and confidence across road and track use.

Fast Road Setup

Perfect for fast road driving with occasional trackday use.

• Front: 120 N/mm

• Rear (Divorced): 130 N/mm

• Rear (True Coilover): 70 N/mm

Track Setup

Provides maximum control, sharper response, and reduced body roll under aggressive driving.

• Front: 140 N/mm

• Rear (Divorced): 160 N/mm

• Rear (True Coilover): 90 N/mm
  
  True rear spring rates appear lower due to different mounting ratios and spring positions – overall stiffness is comparable.
  

Custom Options Available

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

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 sources
  
  This upgrade is highly recommended for competition cars or any application where setup tuning speed matters. Contact us before ordering to include this option.

Race-Grade Construction and Materials

The R3 system uses Nitron’s large-diameter piston design, ultra-low friction internals, and a monotube layout to deliver consistent, fade-resistant damping performance under extreme use.

All key components are made from lightweight, corrosion-resistant alloys with hard-anodised and titanium finishes, ensuring long-term durability even in wet weather or endurance conditions.

Bi-Axis Hose Fittings (Remote Reservoir Kits Only)

Nitron’s proprietary Bi-Axis hose fittings provide flexibility when mounting remote reservoirs. They simplify installation and allow for cleaner, neater routing in tight engine bays or race-prepped interiors.
