Nitron NTR-R1 Coilover Kit for 42 Audi R8

The Audi R8 is a mid-engine sports car with the platform to be genuinely fast in the right hands, but the factory suspension is calibrated for a broad range of drivers and conditions rather than for extracting the most from the chassis. The Nitron NTR-R1 coilover kit for the 42 R8, covering both V8 and V10 variants, 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 from the street to the circuit. Hard-anodized 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

• Every Nitron shock starts with precision components that have been through a thorough design and development process before they reach final assembly. The modular construction gives engineers the flexibility to tailor each application properly, without compromising how individual parts are made or how they perform together. Components are machined to tight tolerances and inspected one by one by trained technicians as part of a strict quality control process. New materials, finishes, and processes go through extensive validation before adoption, with Nitron-specific technologies integrated to produce shocks that genuinely outlast and outperform competing options on the road and track. That standard of engineering is what Nitron’s reputation is 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 pull a generic damper off a shelf and adjust the valving to fit. Every application goes through a dedicated development process, with components, spring rates, and damping characteristics engineered specifically for the platform in question. That means the geometry, weight distribution, and suspension travel of a given car are factored into the design from the start, not compensated for after the fact. It’s the difference between a kit built for your car and a kit built for a category of cars your vehicle happens to fall into.

Frequently Asked Questions

• Which Audi R8 42 variants does this kit fit? The Nitron NTR-R1 coilover kit covers the Audi R8 4.2 V8 quattro (2007-2015), R8 5.2 V10 quattro (2009-2015), R8 GT (2011-2015), and R8 V10 Plus (2013-2015), all within the 42 generation. The kit is also compatible with both Coupe and Spyder body styles across these variants.
• What spring rate options are available for the 42 R8 NTR-R1 kit? Two specs are recommended by Nitron and offered as standard options. The Fast Road Spec runs 550lbs/inch (96N/mm) front and 750lbs/inch (131N/mm) rear. The Track Day Spec steps up to 700lbs/inch (123N/mm) front and 900lbs/inch (158N/mm) rear, reflecting the mid-engine layout’s weight distribution and the higher loads generated on circuit. Custom spring rates are also available; contact us directly for a consultation.
• Why are the rear spring rates considerably higher than the front on the R8? The R8’s mid-engine layout places the majority of the car’s weight over the rear axle. The spring rates on this kit are calibrated around that specific weight distribution, with stiffer rear springs to match the load and maintain balanced handling rather than applying a generic front-to-rear ratio.
• 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.
