The 488 already has a fairly capable suspension from the factory; what does the NTR-R1 actually change?

The factory setup on the 488 GTB and Spider is calibrated for a broad range of drivers and conditions, which means it leaves performance on the table for anyone pushing the car seriously on track or a demanding road. The NTR-R1 replaces that with hardware drawn directly from the R3 race platform, giving the chassis a damping setup that's actually matched to how the car performs under load rather than approximating it.

Is the NTR-R1 the right choice for track use, or should I be looking at the NTR-R3?

The NTR-R1 covers serious track use without compromise; it shares core components with a kit built for professional competition and the hardware behind the combined adjustment is the same quality as the R3. The difference is interface, not capability. If you need fully independent high and low speed compression control to dial in setup across different circuits, the R3 is the step up. If combined adjustment suits your approach, the R1 is the correct kit.

How does combined 2-way adjustment work on the NTR-R1?

Compression and rebound are adjusted together through a single 24-click range rather than independently. It keeps the setup process straightforward without sacrificing the quality of the hardware making those adjustments, and covers a wide range of road and track conditions within that range.

Is this kit fully serviceable long term?

Yes. Every NTR-R1 is hand-built to order and fully serviceable, so replacement parts and rebuild services are available through Nitron's service network well beyond the initial purchase.

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-R1 Coilover Kit for F142M Ferrari 488 GTB / Spider

The Ferrari 488 GTB and Spider have the chassis to be genuine performance cars, but the stock suspension limits what they can actually do when the road gets serious or a track day enters the picture. The Nitron NTR-R1 closes that gap with precision-engineered combined 2-way damping adjustment drawn directly from the R3 race platform, sharing core components with a kit built for professional competition. Every unit is individually hand-built with ultra-low friction components that deliver consistent, fade-resistant damping from the street to the circuit, and with each kit custom built, custom sprung, and fully serviceable, the investment holds up well past a single season.

Unique Technology

Nitron builds every shock from components that go through a rigorous design and development process long before they reach final assembly. The modular construction gives engineers the room to develop each application on its own terms without cutting corners on part quality or how everything holds together under real load. Tight tolerances, individual inspection by trained technicians, and quality control that runs through the entire production process rather than just the end of it; that discipline, combined with proprietary Nitron technologies built in throughout, produces shocks that hold their own against the competition on both road and track.
- 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. Components, spring rates, and damping characteristics are developed around what each variant actually needs. The geometry, suspension travel, and the way the 488 loads the chassis all shape the design from day one rather than being addressed after the fact.

About Nitron Suspension

Nitron Suspension has been at the forefront of precision suspension engineering since 1998, founded by Guy Evans with the goal of building high-performance shocks for enthusiasts and professionals alike. 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.
