What is the practical difference between high speed and low speed compression adjustment?

Low speed compression controls damping response during slow suspension movements; body roll, weight transfer, and braking dive. High speed compression handles the faster inputs; road surface impacts, curbs, and sharp direction changes. Having independent control over both means you can tune body control and ride quality separately rather than making one adjustment that affects everything at once.

How does the NTR-R3 differ from the NTR-R1 for the 488?

The NTR-R1 uses combined 2-way adjustment, meaning compression and rebound are adjusted together. The NTR-R3 separates high speed compression, low speed compression, and rebound into three independently adjustable circuits, giving a significantly wider tuning range for drivers and engineers who need that level of control across different circuits and conditions.

Is the NTR-R3 suitable for road use as well as track?

Yes. The spring rates and damping characteristics are developed specifically around the 488's geometry and chassis loading, covering both road and circuit use. The 3-way adjustment range is wide enough to suit both without requiring separate setups.

Can I run custom spring rates?

Yes. A Fast Road Spec rate is available as standard, but custom spring rates are available on request.

Description

Nitron NTR-R3 Coilover Kit for F142M Ferrari 488 GTB / Spider

The Nitron NTR-R3 Coilover Kit for the Ferrari 488 GTB and Spider is built for drivers and engineers who want to work with the chassis rather than around it. Independent 3-way damping adjustment with separate high and low speed compression control gives the range needed to properly dial the car in across different circuits and conditions, with the geometry and chassis loading of the 488 factored into the spring rates from the start. Hose reservoirs are fitted front and rear, keeping high and low speed compression adjustment accessible at both ends. A large diameter piston and ultra-strong piston rod sit at the core of the design, providing the damping control and feedback that serious setups depend on. The R3 is a proven race winner with lap records across a wide range of international motorsport formulas, and every kit is custom built, custom sprung, and fully serviceable.

Specialized Bi-Axis Hose Fittings

Nitron R3 hose shocks use Nitron’s own 720-degree Bi-Axis fittings exclusively; a proprietary design that delivers clean, precise installation without the fitment compromises that come with conventional end fittings.

Unique Technology

Nitron builds every shock from precision components that go through a thorough design and development process well before final assembly. The modular construction gives engineers the flexibility to approach each application on its own terms without cutting corners on part quality or how components perform together under load. Everything is machined to tight tolerances and inspected individually by trained technicians, with quality control running through every stage of production rather than being concentrated at the end. New materials, finishes, and processes are validated extensively before adoption, with proprietary Nitron technologies integrated throughout to produce shocks that consistently hold up against the competition on road and track. That engineering standard is what 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 accounts for the Ferrari 488 GTB and Spider’s suspension geometry and chassis dynamics from the ground up rather than adapting an existing application to fit. The geometry, suspension travel, and the way the 488 loads the chassis under hard driving all shape the component choices, spring rates, and damping characteristics from day one. That’s what separates a kit developed for this specific car from one that was built for the platform category and happens to cover it by extension.

Over 200 dealers now carry Nitron products across Europe, Asia, the US, Australasia, and Africa. In 2008, the company moved into a dedicated facility in the UK’s Motorsport Valley, adding dynamometers, 5-axis CNC machines, and 3D CAD capabilities to support both growing demand and continued product development. A second expansion came in 2023 with a new office in Murrieta, California. The team behind every Nitron product draws from deep backgrounds in machining, materials technology, hydraulics, bike engineering, and F1 racing, with many engineers bringing firsthand experience as competitive drivers and riders. That depth of knowledge across both the technical and competitive sides of motorsport shapes every product Nitron develops.

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.
