Motorsport Suspension Control for the E9X M3

The Nitron NTR R3 Coilover Kit is a championship-winning suspension solution for drivers who demand top-tier performance, precision, and adjustability on road and track.

Compatibility:
This kit is designed for all BMW E9X M3 variants — including the E90 Saloon, E92 Coupe, and E93 Convertible — produced between 2007–2013

With fully independent 3-way damping adjustment (rebound, fast compression, and slow compression), the NTR R3 delivers class-leading grip, composure, and control.


Key Features of the Nitron NTR R3 Kit

  • 3-way independent damping adjustment

  • Rebound, fast compression & slow compression control

  • External piggyback or remote reservoir options

  • Large-diameter pistons for consistent, fade-free damping

  • True or Divorced rear spring layout

  • Compatibility: BMW E90 / E92 / E93 M3 (2007–2013)

  • Bi-Axis hose fittings on remote reservoir kits

  • Fully serviceable and rebuildable

  • Hard-anodised and titanium-finished components

  • Hand-built to order in the UK


Spring Rate Options – Tuned by Nitron for the E9X M3

Nitron's recommended rates for the E9X platform strike a balance between road compliance and sharp, track-focused control. Choose from two configurations:

Fast Road Setup

  • Front: 120 N/mm

  • Rear (Divorced): 120 N/mm

  • Rear (True Coilover): 350 lbs/inch (≈62 N/mm*)

Track Setup

  • Front: 140 N/mm

  • Rear (Divorced): 140 N/mm

  • Rear (True Coilover): 400 lbs/inch (≈70 N/mm*)

    True rear spring rates appear lower due to different mounting ratios and spring positions – overall stiffness is comparable.


Custom Options Available

Custom spring rates, lengths, and damper lengths can be specified. Contact us before ordering to tailor your R3 kit to your build.


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

Upgrade to quick-connect dry break fittings to relocate the remote reservoirs into the engine bay or cabin without fluid loss – ideal for serious track use.

Benefits include:

  • Easier and faster access for adjustments

  • Protection from road debris and heat

  • Cleaner, motorsport-style installation

  • Improved consistency through thermal isolation

    Highly recommended for trackday or race-focused builds. Contact us to add this option before ordering.


Race-Grade Construction and Materials

Nitron’s large-diameter pistons, monotube design, and high-pressure internals ensure damping consistency lap after lap. All components are built using lightweight, corrosion-resistant materials with titanium and hard-anodised finishes for long-term durability.


Bi-Axis Hose Fittings (Remote Reservoir Kits Only)

All remote reservoir kits feature Nitron’s Bi-Axis fittings, allowing flexible, secure routing of hoses during install. These reduce stress on fittings and simplify placement in tight engine bays or interiors.


Built to Order – Precision Engineering from the UK

Each NTR R3 kit is hand-assembled to spec at Nitron’s UK facility. Lead time is typically 2–3 weeks. Contact us for the most up-to-date ETA.

They fit and they work!
Size: 72880-FL00A
We purchased these a couple of months ago, and we installed one in our 2024 Subaru Outback Limited XT right away. We just wanted to use it for awhile before we left a review. First, it fit perfectly in our Outback. There is a very faintly printed arrow on one side showing which way the airflow is supposed to go when installing it. Pay attention to that arrow. Second, these air filters really work. They have even filtered out bad smells and light smoke we have had to drive through. They are easy enough to replace yourself, and you can save some serious money over having a mechanic do it. If you can work a screwdriver, you can probably replace a car's air filter yourself. At least that's been our experience with all the different cars we have owned. We are very satisfied with these filters and would recommend them to others.
