Does this kit fit the C8 Corvette Z51 package?

Yes. The Nitron NTR-R1 is compatible with the C8 Corvette Stingray, the Z51-optioned Stingray, and the C8 Z06. The Z51 is an option package rather than a separate model, so fitment carries across without issue.

My C8 was optioned with the factory front axle lift. Which kit do I need?

If your C8 came with the factory front axle lift system, the NTR-R1 with OEM FAL Integration is the correct version to choose. That variant is built to retain the factory FAL functionality after installation.

Do the factory leaf springs need to be removed for installation?

Yes. The C8 Corvette uses a transverse composite leaf spring setup front and rear from the factory, and those are removed as part of the installation process. The NTR-R1 replaces the factory damping and springing setup entirely.

What does 24 clicks of combined adjustment mean on the NTR-R1?

The NTR-R1 uses a 2-way combined adjustment, meaning compression and rebound are adjusted together through a single 24-click range rather than independently. It draws directly from the R3 race platform and shares core components with a kit built for professional competition, so the adjustment range covers serious use despite the simplified adjustment interface.

Can I run custom spring rates with the NTR-R1?

Yes. Recommended rates are available for both Fast Road Spec and Track Day Spec configurations, but custom spring rates are available on request.

Description

Nitron NTR-R1 Coilover Kit for C8 Chevrolet Corvette Stingray / Z06

The C8 Corvette Stingray and Z06 are capable platforms that the factory suspension doesn’t fully serve when the driving gets serious. The damping hardware was calibrated for a broad audience rather than a driver who wants to work with the chassis rather than around it. The Nitron NTR-R1 addresses that 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. Installation removes the factory leaf springs entirely, replacing the passive setup with something built around how the Stingray and Z06 actually perform under load. 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, it’s an investment that holds up well beyond 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 C8 Corvette Stingray and Z06 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 platform actually needs. The geometry, suspension travel, and the way each variant loads the chassis all shape the design from day one rather than being addressed after the fact.

Notes

Factory leaf springs are removed for installation
This kit does not integrate with Front Axle Lift systems. Nitron offers two additional variants for C8’s optioned with the factory front axle lift. The OEM FAL Integration variant is built to work directly with the factory system, retaining it after installation. The Standalone FAL variant replaces the factory system entirely with Nitron’s own front axle lift setup. If your C8 came with the factory FAL, either of those variants is the correct route rather than this kit.
Custom spring rates also available, please contact us directly here for more information or for a consultation on custom rates

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.
