How does the elec-TRON R1 integrate with the Alfa Romeo Giulia Quadrifoglio's electronics?

The elec-TRON R1 integrates directly with the Giulia Quadrifoglio's DNA electronic control system, requiring no additional hardware or modification. Damping is managed entirely through the OEM system, so all factory features continue to function as intended with the Nitron hardware installed in place of the stock dampers.

Does the elec-TRON R1 require manual damping adjustment?

No. Damping is fully controlled by Nitron's proportional solenoid valve and managed by the DCU. The system monitors g-load, vehicle speed, road conditions, and driver inputs, making adjustments every six milliseconds without any manual input required.

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

The NTR-R1 uses combined 2-way manual damping adjustment controlled by the driver through a physical adjuster. The elec-TRON R1 replaces that with Nitron's proportional solenoid valve and DCU-controlled electronic damping, integrating with the Giulia Quadrifoglio's DNA system for fully automatic adjustment. Both kits share R3-derived hardware, but the elec-TRON R1 removes the need for any manual setup.

Are droplinks included with the kit?

No, droplinks are not included. The kit consists of four coilovers and adjustable top mounts covering front and rear, with precision bearing spacers supplied as required.

What other suspension options are available for the Alfa Romeo Giulia Quadrifoglio?

Nitron offers several kits for the 952 Giulia Quadrifoglio; the NTR-R1, NTR-R3, elec-TRON R3, RoadSport, and elec-TRON RoadSport. Each targets a different level of adjustment and use case, from street-focused setups to full race configurations.

Is the Nitron elec-TRON R1 serviceable after purchase?

Yes. Every elec-TRON R1 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 R1 Coilover Kit for 952 Alfa Romeo Giulia Quadrifoglio

The Nitron elec-TRON R1 coilover kit for the 952 Alfa Romeo Giulia Quadrifoglio brings electronic damping control through Nitron’s proportional solenoid valve, with all damping managed by the DCU. The kit includes adjustable top mounts and race springs, covering the same broad adjustment range as the R3 without the independent compression adjustment and remote reservoirs. 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 that doesn’t ask much of the driver to get the most out of it.

elec-TRON

Nitron’s elec-TRON system starts with a proprietary proportional solenoid valve fitted to each individual shock, giving the DCU precise, independent damping control at every corner. The system monitors g-load, vehicle speed, road conditions, and driver inputs simultaneously, making damping adjustments every six milliseconds. For reference, a human eye blink takes somewhere between 100 and 150 milliseconds. That processing speed means the suspension is reacting to what the road and the driver are doing in real time, not catching up after the fact. elec-TRON is available in two configurations; OEM-Integration for vehicles with factory electronic damping systems, and Standalone Electronic Damping for platforms without.

Integration with OEM Electronic Systems

For vehicles that come from the factory with an electronic damping system, the Nitron elec-TRON kit installs as a direct bolt-in replacement, integrating with the OEM computer without modification. Factory features continue to function as intended; BMW’s EDC, Porsche’s PASM, and similar systems retain full operation, just with significantly more capable hardware doing the work underneath the car.

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 vehicle shape the design from the start, not as corrections added later. That’s what separates a kit engineered for your car from one that was simply made to fit 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.
