Does this Testarossa NTR-R1 coilover kit fit both the original Testarossa and the 512 TR?

Yes. This kit is built for the F110 chassis platform shared by the Testarossa and the later, wider-tracked 512 TR.

What kind of adjustment does the NTR-R1 offer?

The NTR-R1 uses a combined 2-way adjuster for compression and rebound at each corner, rather than the independent high and low speed adjustment found on the NTR-R3.

What kind of reservoir does this Testarossa NTR-R1 coilover kit use?

The R1 uses an internal reservoir built into the damper body, so there's no external hose or piggyback canister to route around the rear end.

Does this coilover kit affect the Testarossa's factory suspension geometry?

No. The kit replaces the dampers, springs, and top mounts, it doesn't alter the unequal-length double wishbone geometry the car was built with.

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 NTR-R1 Coilover Kit for F110 Ferrari Testarossa / 512 TR

Nitron’s Testarossa NTR-R1 coilover kit replaces a suspension setup that’s been chasing consistency for three or four decades now, and on a car with unequal-length double wishbones at all four corners and a flat-12 hanging out back over the transaxle, that consistency matters more than most owners realize until they’ve driven one on Nitron dampers. This NTR-R1 kit gives the F110 chassis, both the original Testarossa and the later, wider-tracked 512 TR, a 2-way combined compression and rebound adjuster at each corner, letting an owner dial in a single, balanced setting rather than juggling separate high and low speed circuits. The internal reservoir design keeps everything self-contained in the damper body, no external hose or piggyback canister to route around a rear end that’s already tight with the engine and transaxle package. Adjustable top mounts and race springs come standard, and every kit is custom built and fully serviceable.

Unique Technology

Every Nitron shock goes through machining, inspection, and validation long before it’s called finished, with each component checked individually by a trained technician rather than sampled from a batch. The modular design behind the NTR platform means this Testarossa and 512 TR application was built around what the chassis actually needs, not adapted from a part number developed for a different car. New materials, finishes, and processes only reach production after they’ve been thoroughly proven out, and Nitron’s own engineering carries through the whole build instead of being layered onto something generic. That discipline is what’s kept the brand ahead of the competition since long before most modern coilover manufacturers existed.
- 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 modern mid-engine platform and adjust the valving until it works on a Testarossa or 512 TR. This NTR-R1 application is developed specifically for the F110 chassis’ unequal-length double wishbone geometry at all four corners, accounting for the weight of a longitudinally mounted flat-12 sitting over the transaxle rather than assuming it behaves like a front-engine GT car. That’s the difference between a kit built for this platform and one that was only ever adjusted to fit it.

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.
