Nitron NTR-R3 Coilover Kit for Aston Martin DB9

The Aston Martin DB9 has the chassis to be significantly faster than its grand tourer brief suggests, but unlocking that requires suspension capable of being set up with genuine precision rather than adjusted in broad strokes. The Nitron NTR-R3 coilover kit for the DB9 is built for that level of development work; independent 3-way damping adjustment with separate high and low speed compression control gives drivers and engineers the range needed to properly dial the car in across different circuits and conditions. A large diameter piston and ultra-strong piston rod sit at the core of the design, providing the damping control and feedback that serious setups depend on. The kit uses remote hose mounted reservoirs, keeping high and low speed compression adjustment accessible at both ends without adding complexity to the installation. The R3 is a proven race winner with lap records across a wide range of international motorsport formulas, and every kit is custom built, custom sprung, and fully serviceable. Hard-anodised titanium finish parts and high-grade materials keep corrosion out and weight in check, so the dampers maintain their performance standard season after season.

Unique Technology

• Nitron builds every shock from precision components that go through a thorough design and development process long before final assembly. The modular construction gives engineers the flexibility to approach each application on its own terms without cutting corners on part quality or how components perform together under load. Everything is machined to tight tolerances and inspected individually by trained technicians; that quality control runs through every stage of production rather than being concentrated at the end. New materials, finishes, and processes are validated extensively before adoption, with proprietary Nitron technologies integrated throughout to produce shocks that consistently hold up against the competition on road and track. That engineering standard is what the brand has been built on 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

Specialized Bi-Axis Hose Fittings

• Nitron R3 Hose shocks use Nitron’s own 720 degree Bi-Axis fittings exclusively; a proprietary design that delivers clean, precise installation without the fitment compromises that come with conventional end fittings.

Bespoke Engineering

• Nitron doesn’t adapt a generic damper to fit a car; they engineer one around it. Every application goes through a dedicated development process where components, spring rates, and damping characteristics are determined by the specific platform, not borrowed from something close enough. The geometry, weight distribution, and suspension travel of the vehicle are part of the design from the beginning, not corrections introduced later. That’s the difference between suspension that works with a car and suspension that was developed for it.

Frequently Asked Questions

• Does the Nitron NTR-R3 coilover kit fit all Aston Martin DB9 model years? The Nitron NTR-R3 coilover kit is confirmed to fit the Aston Martin DB9 from 2004 to 2016. If you’re unsure about your specific build date or variant, we are happy to assist.
• What is the difference between the NTR-R3 and NTR-R1 coilover kits? The NTR-R3 uses independent 3-way damping adjustment, giving separate control over high speed compression, low speed compression, and rebound. The NTR-R1 uses combined 2-way adjustment, where bump and rebound are controlled together through a single adjuster. The R3 is the race-focused option for drivers and engineers who need precise, independent control over each damping parameter; the R1 is the more straightforward setup suited to road use and track days where that level of granularity isn’t required.
• What spring rate options are available for the Aston Martin DB9 NTR-R3 kit? Two specs are recommended by Nitron and offered as standard options. The Fast Road Spec runs 450lbs/inch (79N/mm) front and 500lbs/inch (88N/mm) rear. The Track Day Spec steps up to 500lbs/inch (88N/mm) front and 550lbs/inch (96N/mm) rear. Custom spring rates are also available; contact us directly for a consultation.
• What reservoir type does the NTR-R3 use on the DB9? The NTR-R3 for the DB9 uses remote hose mounted reservoirs, keeping high and low speed compression adjustment accessible at both ends of the car without adding complexity to the installation.
• Are droplinks included with the kit? No, droplinks are not included. The kit consists of four coilovers, reservoirs, hoses, and top mounts covering front and rear.
• Is the Nitron NTR-R3 serviceable after purchase? Yes. Every NTR-R3 kit is fully serviceable. Nitron hand-builds each unit to order, and the design supports long-term maintenance rather than requiring full replacement when performance eventually needs refreshing.

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.
