How does 3-way adjustment help a short-wheelbase car like the Fiesta ST?

The Nitron Fiesta ST NTR-R3 lets you control pitch and roll separately from how the car handles bumps. Low-speed compression and rebound manage nose dive under braking and body roll on turn-in. High-speed compression manages curbs and sharp hits. You can make the ST flatter and more stable without making it harsh over rough tarmac.

Why does the Nitron Fiesta ST NTR-R3 use piggyback reservoirs instead of hose reservoirs?

Piggyback reservoirs mount directly on each damper body, so the Nitron Fiesta ST NTR-R3 needs no hoses or separate reservoir brackets. On a compact car with limited space at both ends, that keeps the install simple. The compression adjusters are still easy to reach, and the extra oil volume still helps keep damping consistent under heat.

What does the full coilover rear on the Nitron Fiesta ST NTR-R3 allow?

The Nitron Fiesta ST NTR-R3 mounts each rear spring around the damper body, the same as the front. That gives you ride height and spring preload adjustment directly at the rear dampers. You can set rake and corner weights accurately, which matters when you’re fine-tuning balance with independent 3-way damping.

Does the Nitron Fiesta ST NTR-R3 come with top plates?

Yes. Nitron top plates are included with every Nitron Fiesta ST NTR-R3 kit, so the front struts install without reusing the factory mounts. Worn original mounts can add play that hides small adjustments. Starting with new top plates means the changes you make at the adjusters show up clearly in how the car drives.

Should a Fiesta ST owner choose the Nitron NTR-R3 or the Nitron NTR-R1?

If the Fiesta ST is mainly a track or competition car, choose the Nitron NTR-R3. It adds independent rebound, low-speed compression and high-speed compression, plus piggyback reservoirs for more stable damping over long sessions. The Nitron NTR-R1 uses one combined adjuster and no reservoirs, which suits road driving and occasional track days.

Can the Nitron Fiesta ST NTR-R3 be rebuilt and revalved?

Yes. Every Nitron Fiesta ST NTR-R3 damper is fully serviceable and rebuildable, including revalving and spring changes. Track and race Fiesta STs are often revalved when moving to slicks, adding power or changing series, and a rebuild between seasons keeps the dampers performing as new.

Description

Nitron NTR-R3 Coilover Kit for B299 Ford Fiesta ST

A short-wheelbase car like the Fiesta ST reacts to weight transfer almost immediately. Stand on the brakes and the nose dives. Turn in hard and the body rolls onto the outside front tire before the rear has settled. Hit a curb mid-corner and the whole car feels it. The Nitron Fiesta ST NTR-R3 coilover kit gives you a separate adjuster for each of those behaviors, with independent rebound, low-speed compression and high-speed compression at every corner. Low-speed compression controls pitch and roll, so you can calm the dive under braking and keep the car flatter through the turn. High-speed compression handles the sharp hits, letting the ST ride over curbing and broken tarmac without being thrown off line. Piggyback reservoirs sit directly on the dampers at both ends, so there are no hoses to route through a small engine bay or around the rear of the car. The rear is a full coilover for proper ride height and corner-weight adjustment. Altogether, the Nitron Fiesta ST NTR-R3 is the most adjustable damper Nitron builds for the car.

Unique Technology

The Nitron NTR-R3 is the same damper design that has won races and set lap records across international motorsport. It is built around a large-diameter piston and an ultra-strong piston rod. The larger piston displaces more oil per millimeter of movement, so each adjuster click makes a clear, repeatable change. On a light car where small changes are easy to feel, that precision makes setup faster and more predictable. Each piggyback reservoir adds oil volume and carries the high- and low-speed compression adjusters, which keeps them easy to reach. The extra volume also helps damping stay steady as the oil heats up. When the Nitron Fiesta ST NTR-R3 is pushed hard through a long session, it keeps the balance you set instead of gradually going soft.
- 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

Each Nitron Fiesta ST NTR-R3 kit is built by hand after the order is placed, with springs and valving specified for that car’s purpose. A road-registered ST doing regular track days, a time-attack build on R-compound tires and a caged club racer each need something different, and Nitron sets up the kit for whichever one it’s going on. Hard-anodized components and titanium hardware cut weight and resist corrosion, which helps on a car that may see a wet circuit on Sunday and salted roads on Monday. The dampers are made to be maintained over years of use. Every Nitron NTR-R3 unit can be fully serviced and rebuilt, and revalving for new tires, more power or a different series is part of keeping the kit matched to the car.

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.
