Nitron NTR-R1 Coilover Kit for Aston Martin DB9

The Aston Martin DB9 is a grand tourer with genuine performance underneath the bodywork, but the factory suspension is tuned for comfort over capability, and that becomes apparent when the road gets demanding or a track day exposes what the platform is actually capable of. The Nitron NTR-R1 coilover kit for the DB9 closes that gap with precision-engineered, combined 2-way damping adjustment drawn directly from the R3 race platform, sharing core components with a kit built for professional competition. There’s no remote canister to package around, and every unit is individually hand-built with ultra-low friction components that deliver consistent, fade-resistant damping whether the car is covering ground on a long road route or being pushed on circuit. Hard-anodised titanium finish parts and high-grade materials keep corrosion out and weight in check, and with each kit custom built, custom sprung, and fully serviceable, it’s an investment that holds up well beyond a single season.

Unique Technology

• Nitron builds every shock around precision components that go through a thorough design and development process long before final assembly. The modular construction gives engineers the room to work through each application properly on its own terms, without cutting corners on how parts are made or how they hold up together under load. Components are machined to tight tolerances and inspected individually by trained technicians; that quality control runs through the entire production process, not just the end of it. New materials, finishes, and processes go through extensive validation before they’re brought in, with proprietary Nitron technologies integrated throughout to produce shocks that consistently outlast and outperform competing options on road and track. That standard is what the brand’s reputation has been built on.
  • 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 reach for a generic damper and rework the valving to suit. Every application goes through a dedicated development process where components, spring rates, and damping characteristics are engineered around the specific platform from the start. The geometry, weight distribution, and suspension travel of the vehicle are built into the design before anything else, not factored in as corrections later. That’s what sets a kit engineered for a car apart from one that was simply built to fit the same category.

Frequently Asked Questions

• Does the Nitron NTR-R1 coilover kit fit all Aston Martin DB9 model years? The Nitron NTR-R1 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 spring rate options are available for the Aston Martin DB9 NTR-R1 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.
• How does the 2-way combined damping adjustment work? The NTR-R1 uses a single adjuster controlling both bump and rebound together across 24 clicks of combined adjustment. This keeps setup straightforward without sacrificing the ability to meaningfully tune the damping character for different road conditions or track surfaces.
• Are droplinks included with the kit? No, droplinks are not included. The kit consists of four coilovers and top mounts covering front and rear, with precision bearing spacers supplied as required.
• Is the Nitron NTR-R1 serviceable after purchase? Yes. Every NTR-R1 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.
