Nitron NTR-R3 Coilover Kit for FD Mazda RX-7

The Nitron NTR R3 Coilover Kit for the FD3S Mazda RX-7 is built for drivers and engineers who want to properly develop the car’s setup across different circuits and conditions. The FD3S’s front mid-engine layout and near 50/50 weight distribution reward a suspension that can be tuned with real precision rather than dialed in by approximation, and the R3 is built for exactly that level of work. Independent 3-way damping adjustment with separate high and low speed compression control gives the range needed to address specific handling characteristics without trade-offs. Piggyback reservoirs front and rear keep high and low speed compression adjustment accessible at both ends without adding complexity to the installation. 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 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.

Unique Technology

Nitron starts every shock with 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 compromising part quality or how components perform together under real load. Everything is machined to tight tolerances and inspected individually by trained technicians; that standard of quality control runs through every stage of production, not just the end of it. New materials, finishes, and processes go through extensive validation before they’re adopted, with proprietary Nitron technologies built in throughout to produce shocks that consistently hold up against the competition on road and track. That’s the engineering foundation 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

Bespoke Engineering

Nitron doesn’t adapt a generic damper to fit the FD3S Mazda RX-7; they engineer one around it. Every application goes through a dedicated development process where components, spring rates, and damping characteristics are shaped by the specific platform, not carried over from something similar enough to work. The geometry, weight distribution, and suspension travel of the FD3S are part of the design from day one, not corrections introduced later. That’s the difference between suspension that works with a car and suspension that was purpose-built for it.

Frequently Asked Questions

How does the R3 justify the step up from the R1 on the FD3S? The R1 uses a single combined adjuster for compression and rebound. The R3 separates high speed compression, low speed compression, and rebound into three independent circuits with 16, 26, and 24 clicks respectively. On a car as sensitive to setup as the FD3S, that separation lets you address a specific handling characteristic without affecting everything else at once. You can tune for a particular circuit or surface without the adjustment trade-offs that come with a combined system.
What is the difference between the Fast Road and Track Day spring rate specs? The Fast Road spec is tailored for drivers who push hard on the road and want improved chassis response without giving up daily usability. The Track Day spec steps up the spring rates and is for drivers running the car regularly on circuit where body control and consistency under load take priority. Both use the same R3 damper hardware; the difference is in the spring rates.
How does the FD3S’s weight distribution factor into the R3 setup? The front and rear spring rates are deliberately asymmetric and are calibrated around the FD3S’s specific geometry and near 50/50 weight balance from the start of Nitron’s development process. The split between front and rear reflects what the car actually needs, not a generic starting point that was adjusted to fit.

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.
