Does this R33 GT-R elec-TRON R3 coilover kit include the DCU?

Yes. The DCU is included with this kit and manages the solenoid valve independently, since the R33 GT-R doesn't have a factory electronic damping system to integrate with.

What kind of reservoirs does this kit use?

Piggyback reservoirs mount directly to each damper front and rear, keeping the oil and gas chambers close to the shock instead of running hose lines out to a separate canister.

Does the manual compression adjustment still work alongside the electronic control?

Yes. The independent manual high and low speed compression adjustment sets the mechanical baseline, and the DCU adjusts the solenoid valve in real time on top of that, so both systems work together rather than one replacing the other.

How does the GT-R elec-TRON R3 compare to the R1 version of this kit?

The R1 also relies on the solenoid valve and DCU with manual knobs available but not required, while this R3 kit pairs that same electronic control with independent high and low speed compression adjustment as a core part of the design.

Does this kit affect the R33's ATTESA E-TS or Super-HICAS systems?

No. The kit only replaces the dampers, reservoirs, and top mounts, it doesn't alter the ATTESA E-TS drivetrain or the Super-HICAS rear steering.

Can custom spring rates be ordered with this kit?

Yes. Every kit is custom built to order, and custom spring rates beyond the standard setup are available by contacting us directly for a consultation.

Description

Nitron elec-TRON R3 Coilover Kit for R33 Nissan Skyline GT-R

The R33 GT-R elec-TRON R3 coilover kit combines Nitron’s proportional solenoid valve with independent manual high and low speed compression adjustment, so the DCU handles the active side of damping while the mechanical baseline can still be set by hand. Piggyback reservoirs mount front and rear, keeping the oil and gas chambers close to each damper rather than running hose lines out to a remote canister. Because the R33 never came with a factory electronic damping system, the DCU is included as part of this kit rather than sold separately, managing the solenoid valves independently of anything the ATTESA E-TS chassis shipped with from the factory. Adjustable top mounts and race springs come standard, and the whole setup is built for an R33 owner who wants to extract everything the platform has, whether that’s a track day or just keeping up with modern traffic on the street.

elec-TRON

Each shock in the elec-TRON R3 carries its own proprietary proportional solenoid valve, and on the R33 that valve is managed entirely by Nitron’s own DCU rather than a factory electronic damping system, since the car was never built with one. The system tracks g-load, vehicle speed, road surface, and driver input at once, adjusting damping every six milliseconds, well ahead of the 100 to 150 milliseconds it takes a human eye to blink.

elec-TRON DCU (Damper Control Unit)

The DCU is what separates a passive damper from a semi-active one, and on this kit it works alongside the manual compression adjustment rather than replacing it. It tracks the forces acting on the car under braking, cornering, and acceleration, and uses that data to reposition each elec-TRON valve roughly every 5 milliseconds. A control knob on the unit switches between Rain, Tour, Sport, and Race maps, so the driver still sets the overall character while the fine adjustment underneath keeps happening automatically, layered on top of whatever manual compression settings are dialed in.
- Supplied with a custom or universal wiring harness
- Utilizes Arm Cortex-M4 processor
- Independent control of 4 electronic dampers
- 6 position rotary control switch or visual rotary display and control allows user to access a number of pre-installed damping maps (x3 passive and x3 adaptive)
- 2x 3 axis accelerometers
- 1x 3 axis gyroscope
- 200 Hz damping control rate
- Configured for application location and settings
- Ideal for resto-mod applications
- Fully resin bonded

Unique Technology

A Nitron shock doesn’t reach final assembly without going through a long process of machining, inspection, and validation first. Components are held to tight tolerance and checked individually by a trained technician rather than sampled from a batch, and the modular platform behind the elec-TRON R3 gives Nitron room to build this R33 GT-R application around the chassis it’s actually going on rather than adapting a part number built for something else. New materials, finishes, and processes only reach production once they’ve been thoroughly proven out, and Nitron’s own engineering runs through the whole build instead of being layered onto something generic. That discipline is what’s kept the brand ahead of the competition for decades.
- 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 take a damper built for a lighter, front-engine car and adjust the valving until it works on a GT-R. This R33 GT-R elec-TRON R3 kit is developed specifically for the R33’s double wishbone front and multi-link rear geometry, accounting for the added mass and load transfer that come with the ATTESA E-TS all-wheel drive system rather than assuming it behaves like a rear-drive platform. That’s the difference between a kit built for a GT-R and one that was only ever adjusted to fit one.

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.
