How does the elec-TRON R3 integrate with the Alfa Romeo Giulia Quadrifoglio's electronics?

The elec-TRON R3 integrates directly with the Giulia Quadrifoglio's DNA electronic control system, requiring no additional hardware or modification. Damping is managed through the OEM system, so all factory features continue to function as intended with the Nitron hardware in place of the stock dampers.

What is the difference between the elec-TRON R3 and the elec-TRON R1 coilover kits?

Both kits use Nitron's proportional solenoid valve and DCU-controlled electronic damping, but the elec-TRON R3 adds independent manual compression adjustment via piggyback reservoirs, giving drivers and engineers direct control over high and low speed compression on top of the active electronic damping. The elec-TRON R1 handles all damping electronically without the manual compression adjustment capability.

What is the difference between the elec-TRON R3 and the NTR-R3 coilover kits?

The NTR-R3 uses fully manual 3-way independent damping adjustment with separate high speed compression, low speed compression, and rebound control. The elec-TRON R3 adds Nitron's proportional solenoid valve and DCU-controlled active damping on top of that manual compression adjustment, integrating with the Giulia Quadrifoglio's DNA system for real-time electronic damping control alongside the manual setup capability.

Are droplinks included with the kit?

No, droplinks are not included. The kit consists of four coilovers, reservoirs, hoses, and adjustable top mounts covering front and rear.

Is the Nitron elec-TRON R3 serviceable after purchase?

Yes. Every elec-TRON R3 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.

Description

Nitron elec-TRON R3 Coilover Kit for 952 Alfa Romeo Giulia Quadrifoglio

The Nitron elec-TRON R3 coilover kit for the 952 Alfa Romeo Giulia Quadrifoglio combines electronic damping control through Nitron’s proportional solenoid valve with independent manual compression adjustment, giving drivers and engineers control over both the active and mechanical sides of the damping setup. Piggyback reservoirs allow for straightforward independent adjustment of high and low speed compression, while the DCU handles overall damping in real time. Adjustable top mounts and race springs are included, and the kit is built for drivers who want to extract the most from the Giulia Quadrifoglio on road or track without leaving performance on the table.

elec-TRON

Nitron’s elec-TRON system is built around a proprietary proportional solenoid valve fitted to each shock individually, giving the DCU precise, independent damping control at every corner of the car. G-load, vehicle speed, road conditions, and driver inputs are all monitored simultaneously, with damping adjustments made every six 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. elec-TRON is offered in two configurations; OEM-Integration for vehicles equipped with factory electronic damping, and Standalone Electronic Damping for platforms that aren’t.

Integration with OEM Electronic Systems

For vehicles equipped from the factory with an electronic damping system, the Nitron elec-TRON kit goes in as a direct bolt-in replacement, picking up the OEM computer integration without any modification needed. Factory functionality stays intact; systems like BMW’s EDC and Porsche’s PASM continue to operate exactly as designed, with significantly more capable hardware now doing the actual work.

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 a car; 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 vehicle 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.

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.
