Do these Öhlins Road & Track coilovers fit both the Mazda MX-5 NA and NB?

Yes. The Öhlins Road & Track coilovers are designed to fit both the Mazda MX-5 NA and NB platforms. Contact Bulletproof Automotive before ordering to confirm fitment for your specific build or regional variant.

How does the DFV adjustment work on the Mazda MX-5 NA and NB coilover kit?

The Dual Flow Valve (DFV) uses a single gold knob on each damper. Turning it clockwise engages race mode, adjusting low-speed compression, high-speed compression, low-speed rebound, and high-speed rebound all at once. Turning it back returns the damper to road mode. No tools are required for the adjustment.

What is the ride height adjustment range for these coilovers?

The front dampers offer approximately 10 to 35 mm of lowering adjustment. The rear dampers offer approximately 5 to 35 mm. Each corner uses a separate damper length adjuster alongside a spring preload adjuster, so ride height and spring load can be set independently of one another.

Do these coilovers require new top mounts?

No. Both the front and rear assemblies include aluminum ball joint top mounts, so no separate top mount purchase is required. The aluminum ball joint design contributes to sharper steering response and more consistent camber behavior under load compared to the original rubber mounts.

What are the spring rates on the Öhlins MX-5 NA and NB coilover kit?

The front spring rate is 80 N/mm and the rear spring rate is 60 N/mm. The slightly softer rear rate supports the NA and NB weight distribution and rear axle compliance, keeping the car balanced and communicative through corners on both road and track.

Are these Öhlins coilovers TÜV approved?

Yes. The Öhlins Road & Track coilovers for Mazda MX-5 NA and NB carry TÜV approval, confirming they meet the technical and safety standards required for road use in TÜV-regulated markets.

Can these dampers be rebuilt after extended track use?

Yes. Every damper in the Öhlins Road & Track kit for Mazda MX-5 NA and NB is fully rebuildable. This allows for servicing after heavy use and makes custom tuning possible for drivers who want to optimize the setup for a specific track or driving style.

Description

Öhlins DFV Road & Track Coilovers for NA and NB Mazda MX-5 Miata

Öhlins’ DFV Road & Track Coilovers for NA and NB Mazda MX-5 Miata models replace all four dampers and springs with Öhlins kit MAS MI20S1, which Öhlins lists for the NA and NB MX-5 Miata from 1989 to 2005. Aluminum ball joint top mounts come with the kit at all four corners. A gold knob on each damper switches between street and track settings in seconds, and on Öhlins’ recommended setup the car sits about 20 mm lower than stock. It suits the owner who drives to the circuit and home again; a car trailered to every event wants a dedicated track damper.

Design and Performance

The Dual Flow Valve lets one adjuster shift low and high speed compression and rebound together, so road and track settings are a knob turn apart rather than a session of separate changes. Both ends use aluminum monotube shock absorbers, each with a spring preload adjuster and a separate damper length adjuster, so ride height and spring preload are set independently. Each turn of the height adjuster moves ride height by 1.5 mm. Öhlins aluminum ball joint top mounts replace the factory mounts front and rear.

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.
