Nitron NTR-R3 Coilover Kit for 996 Porsche 911 Carrera 4, Carrera 4S, Turbo, and Turbo S

The 996 Porsche 911 Carrera 4, Carrera 4S, Turbo, and Turbo S share a platform with genuine performance capability, and the factory suspension, while capable, leaves real performance on the table when the driving gets serious. The Nitron NTR-R3 coilover kit 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. Droplinks are included so the installation is complete without sourcing additional hardware. Both front and rear units use hose mounted reservoirs with quick-release dry-breaks fitted at both ends, keeping high and low speed compression adjustment accessible 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.

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

Bespoke Engineering

Nitron doesn’t adapt a generic damper to fit the 996 Porsche 911 Carrera 4, Carrera 4S, Turbo, and Turbo S; they engineer one around each platform. Every application goes through a dedicated development process where components, spring rates, and damping characteristics are determined by the specific variant, not borrowed from something close enough. The geometry, weight distribution, and suspension travel of each model 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

How does the R3 justify the step up from the R1 on these 996 variants? 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 AWD and turbocharged platforms like the Carrera 4, Carrera 4S, Turbo, and Turbo S, that separation lets you address a specific handling characteristic without affecting everything else at once; you can tune for a particular circuit or condition without the adjustment trade-offs that come with a combined system.
What are the dry-breaks and why are they fitted front and rear on this kit? Dry-breaks are quick-release fittings on the hose reservoir lines that allow the reservoir to be disconnected cleanly and quickly without fluid loss. Having them at both ends makes reservoir removal and reinstallation straightforward during setup changes or maintenance, which matters more on a kit being used for serious development work across different circuits and conditions.

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.
