The Nitron NTR-R3 Coilover GD WRX STi kit delivers full 3-way independent damping to the bugeye and blobeye Impreza, splitting high and low speed compression from rebound, built around a large diameter piston and ultra-strong piston rod. Piggyback reservoirs front and rear. A proven race winner with lap records across international motorsport; custom built, custom sprung, and fully serviceable.

Designed for narrow-body bugeye and blobeye models, does not fit hawkeye models 2006-2007

Nitron NTR-R3 Coilover Kit for GD Subaru Impreza WRX / WRX STi (bugeye and blobeye)

The Nitron NTR-R3 Coilover GD WRX STi kit is built for owners who want to extract everything the bugeye and blobeye Impreza chassis has to give once the factory dampers stop keeping up. The GD platform responds directly to a serious damper, and the Nitron NTR-R3 coilover for the GD WRX STi is exactly that. Independent 3-way adjustment splits high and low speed compression from rebound, giving you the latitude to set the car up properly for one track and change it meaningfully for the next. At the heart of the Nitron NTR-R3 is a large diameter piston paired with an ultra-strong piston rod, which is what delivers the control and feedback a developing setup on the GD WRX or STi leans on. Piggyback reservoirs front and rear keep that adjustment within easy reach without complicating the install. The R3 platform holds lap records across a broad span of international motorsport, and every Nitron NTR-R3 coilover for the GD WRX STi is built to order, custom sprung, and fully serviceable.

Unique Technology

• Every Nitron shock is built from precision components that have already cleared a full design and development cycle by the time they reach final assembly. The modular construction lets engineers treat each application on its own merits without giving ground on how parts are made or how they work together under load. Each piece is machined to tight tolerances and checked individually by trained technicians, with that quality control woven through the whole process rather than bolted on at the end. New materials, finishes, and processes are validated thoroughly before they reach production, and proprietary Nitron technologies run throughout, producing shocks that consistently stand up to the competition on road and track alike. That’s the engineering standard behind every Nitron NTR-R3 coilover, and the standard the brand has carried since 1998.
  • Basic Damper Design:
    1. End Eye / Top Mount
    2. Damper Piston & Shim Stack
    3. Shaft / Rod
    4. Floating / Separator Piston
    5. Suspension Oil
    6. Compressed Nitrogen Gas

Bespoke Engineering

• Nitron doesn’t take a generic damper and make it fit the GD WRX and STi; they develop one specifically for it. The Nitron NTR-R3 coilover for the GD WRX STi gets its own dedicated process, with components, spring rates, and damping characteristics decided by the bugeye and blobeye platform itself rather than pulled from something close enough to pass. The geometry, weight distribution, and suspension travel of the GD chassis inform the design from the outset instead of being patched in later. That’s what separates suspension that works with a car from suspension that was actually developed for it.

Frequently Asked Questions

• What is the difference between the NTR-R1 and the NTR-R3? The NTR-R1 uses combined 2-way adjustment with 24 clicks controlling both compression and rebound through a single circuit. The Nitron NTR-R3 coilover for the GD WRX STi separates those functions entirely, with 16 clicks of high speed compression, 26 clicks of low speed compression, and 24 clicks of rebound adjusted independently. The R3 gives significantly more range when dialing the car in across different circuits and conditions.
• Can the Nitron NTR-R3 coilover for the GD WRX STi be revalved or adjusted after purchase, and are custom spring rates available? Yes on both. Every Nitron NTR-R3 coilover GD WRX STi kit is fully serviceable and can be revalved or rebuilt by Nitron. Custom spring rates are available at the time of order; contact us directly before ordering if your intended use or setup calls for something outside the standard specification.

About Nitron Suspension

Nitron Suspension has been at the forefront of precision suspension engineering since 1998, founded by Guy Evans with the goal of building high-performance shocks for enthusiasts and professionals alike. Over 200 dealers now carry Nitron products across Europe, Asia, the US, Australasia, and Africa. In 2008, the company moved into a dedicated facility in the UK’s Motorsport Valley, adding dynamometers, 5-axis CNC machines, and 3D CAD capabilities to support both growing demand and continued product development. A second expansion came in 2023 with a new office in Murrieta, California. The team behind every Nitron product draws from deep backgrounds in machining, materials technology, hydraulics, bike engineering, and F1 racing, with many engineers bringing firsthand experience as competitive drivers and riders. That depth of knowledge across both the technical and competitive sides of motorsport shapes every product Nitron develops.
