Does the elec-TRON 3-Way RoadSport require the Electronic Damping Delete Kit on the 981 Cayman GT4 or 982 718 Cayman GT4 and GT4 RS?

No. The elec-TRON kit integrates directly with the factory PASM system and retains full functionality, so no Delete Kit is needed. The Delete Kit is only required when fitting a passive coilover kit such as the standard 3-Way RoadSport.

Can the Nitron elec-TRON 3-Way RoadSport be revalved or adjusted after purchase, and are custom spring rates available?

Yes on both. Every Nitron elec-TRON RoadSport kit is fully serviceable and can be revalved or rebuilt by Nitron. Custom spring rates are available at the time of order; contact us directly before ordering if your intended use or setup calls for something outside the standard Fast Road or Track Day specs.

Description

Nitron elec-TRON 3-Way RoadSport Coilover Kit for 981 Porsche Cayman GT4 / 982 718 Cayman GT4 and GT4 RS

The Nitron elec-TRON 3-Way RoadSport coilover kit for the 981 Porsche Cayman GT4 and 982 718 Cayman GT4 and GT4 RS brings race-derived 3-way damping control to the most track-focused cars Porsche has built in the Cayman line, with the added capability of Nitron’s electronic damping system integrated alongside it. Each shock carries Nitron’s proportional solenoid valve, which works directly with the factory PASM system; no additional controller is required. Unlike many motorsport coilover setups that require replacement top mounts, this kit retains the OEM top plates, preserving factory geometry, NVH characteristics, and ease of installation. The 3-way independent adjustment separates rebound from high and low speed compression on the mechanical side, built around Nitron’s class-leading large diameter piston and ultra-strong piston rod, while PASM handles overall damping in real time through Nitron’s valve hardware. Hose mounted reservoirs front and rear keep that adjustment accessible without adding complexity to the installation. The large range of adjustment and quality of feedback lets an experienced driver fully exploit what these GT4 and GT4 RS chassis are capable of. The R3 platform is a proven race winner with lap records across a wide spectrum of international motorsport formulas, and high-grade materials keep corrosion out and weight in check. Every kit is custom built, custom sprung, and fully serviceable; titanium and hard-anodized parts are hand built to last the lengthiest endurance races, season after season, and the harshest of winters.

elec-TRON

Nitron’s elec-TRON system is built around a proprietary proportional solenoid valve fitted to each shock individually on the 981 Porsche Cayman GT4 and 982 718 Cayman GT4 and GT4 RS, working in conjunction with Porsche’s PASM electronic damping system. G-load, vehicle speed, road conditions, and driver inputs are all monitored simultaneously, with damping adjustments made every 5 milliseconds. A human eye blink takes somewhere between 100 and 150 milliseconds; the elec-TRON system is working at a fraction of that. The suspension is responding to the road and the driver in real time, not reacting after the fact.

Integration with OEM Electronic Systems

The Nitron elec-TRON 3-Way RoadSport installs as a direct bolt-in replacement on the 981 Porsche Cayman GT4 and 982 718 Cayman GT4 and GT4 RS, integrating with Porsche’s PASM system without modification. PASM continues to operate as intended, retaining full factory damping system functionality, just with significantly more capable hardware doing the work underneath the car. No additional controller is required.

Specialized Bi-Axis Hose Fittings

Nitron 3-Way RoadSport hose shocks use Nitron’s own 720-degree Bi-Axis fittings exclusively; a proprietary design that makes for clean, precise installation without the compromises that come with conventional end fittings.

Unique Technology

Nitron builds every shock from precision components that go through a rigorous design and development process well before the unit reaches final assembly. The modular construction gives engineers the flexibility to work through each application properly without cutting corners on how parts are made or how they perform together under real load. Everything is machined to tight tolerances and checked individually by trained technicians; that level of quality control isn’t concentrated at the end of the process, it runs through all of it. New materials, finishes, and processes are put through extensive validation before they’re brought into production, with proprietary Nitron technologies integrated throughout to produce shocks that hold their own against the competition on road and track alike. That discipline in engineering is what the brand has stood on since day one.
- 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 reverse engineer a fit for the 981 Porsche Cayman GT4 and 982 718 Cayman GT4 and GT4 RS. Every application is developed from scratch, with components, spring rates, and damping characteristics built around the specific platform rather than adapted from something in the same ballpark. The geometry, weight distribution, and suspension travel of each variant are factored into the design from the beginning, not addressed as afterthoughts. That’s the gap between a kit that happens to fit a car and one that was actually engineered for it.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
