Nitron elec-TRON R1 Coilover Kit for 996 Porsche 911 Carrera 4, Carrera 4S, Turbo, and Turbo S

The Nitron elec-TRON R1 coilover kit for the 996 Porsche 911 Carrera 4, Carrera 4S, Turbo, and Turbo S brings electronic damping control through Nitron’s proportional solenoid valve, with all damping managed by the Nitron DCU, which is sold separately. Droplinks are included so the installation is complete without sourcing additional hardware. The hardware traces directly back to the R3 platform, so what you’re getting is proven race-derived componentry packaged into a more accessible, straightforward setup; one that works particularly well on these AWD and turbocharged 996 variants, where the platform’s performance foundation is already strong and the suspension just needs to keep up with precision rather than complexity. Every kit is custom built, custom sprung, and fully serviceable.

elec-TRON

The elec-TRON R1 for the 996 Porsche 911 Carrera 4, Carrera 4S, Turbo, and Turbo S runs on Nitron’s Standalone Electronic Damping configuration. Each shock carries its own proprietary proportional solenoid valve, giving the DCU precise, independent damping control at every corner simultaneously. The system monitors g-load, vehicle speed, road conditions, and driver inputs all at once, making damping adjustments every 5 milliseconds. For reference, a human eye blink takes somewhere between 100 and 150 milliseconds. The suspension is reacting to what the road and the driver are doing in real time, not catching up after the fact.

Standalone Electronic Damping System

The Nitron DCU is required for the elec-TRON R1 kit on the 996 Porsche 911 Carrera 4, Carrera 4S, Turbo, and Turbo S and is sold separately. It’s the brain behind the elec-TRON system, transforming a conventional passive damper setup into a precision semiactive platform. Working in conjunction with Nitron’s elec-TRON valve, the DCU continuously processes data from the car every 5 milliseconds; assessing vehicle attitude, braking forces, cornering loads, and acceleration inputs to determine the correct valve position and damping level at any given moment. The result is a suspension system that isn’t set to a fixed damping rate but is constantly optimizing grip and performance in real time based on what the car is actually doing. The DCU is fitted with an adjustable control knob giving the driver access to a range of pre-installed damping maps; Rain, Tour, Sport, and Race; each tuned for a specific driving context. Damping continues to be adjusted continuously within whichever map is selected, so the driver sets the overall character and the system handles the rest.
- Supplied with a custom or universal wiring harness

- 6 position rotary control switch or visual rotary display and control allows user to access a number of pre-installed damping maps (3 passive / 3 adaptive)
- Two 3 axis accelerometers
- 3 axis gyroscope
- 200Hz damping control rate
- Configured for application location and settings
- Ideal for resto-mod applications
- Fully resin bonded

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 develop each application properly on its own terms, without cutting corners on part quality or how components work together under load. Everything is machined to tight tolerances and inspected individually by trained technicians; quality control isn’t a final step here, it runs through the entire process. New materials, finishes, and processes are validated extensively before they’re brought into production, with proprietary Nitron technologies woven throughout to produce shocks that hold up against the competition on both road and track. That level of engineering discipline is what the brand 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 start with a generic damper and work backward from there. Every application is developed from the ground up, with components, spring rates, and damping characteristics determined by the specific platform rather than borrowed from something adjacent. The geometry, weight distribution, and suspension travel of the 996 Porsche 911 Carrera 4, Carrera 4S, Turbo, and Turbo S shape the design from the start, not as corrections added later. That’s what separates a kit engineered for these cars from one that was simply made to fit them.

Frequently Asked Questions

Does the elec-TRON system account for the differences between the Carrera 4, Carrera 4S, Turbo, and Turbo S? Yes. Each variant is custom sprung to order with spring rates and damping characteristics calibrated around its specific weight distribution, AWD system, and suspension geometry. The Turbo’s additional mass and boost hardware are factored into the setup from the start, not carried over from the Carrera 4 application.
Does the DCU come included with this kit? No. The Nitron DCU is required for the elec-TRON R1 to operate and is sold separately, however it is available as an add-on.

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.
