Does the EXEDY Stage 2 Cerametallic Clutch thick disc need a different flywheel?

Turn 14 lists the 10950 for use with the later-model 1.8-liter Miata flywheel, which is not included. Plan to source that flywheel before installing this EXEDY Stage 2 Cerametallic Clutch, or choose the thin-disc 10903, which Turn 14 lists without that requirement.

Will it fit a 1993 Miata LE?

Yes. Turn 14 lists the 10950 for the 1990-1993 Miata with the 1.6-liter engine, including the 1991 SE and 1993 LE, used with the later 1.8-liter flywheel. The kit uses the 22-tooth, 24.3 mm input spline of the five-speed gearbox.

How much power will the thick disc hold?

EXEDY rates the 10950 at 189 lb-ft of torque capacity at the flywheel and 152 lb-ft at the wheels, from 1,169 lb of clamp load. That covers a turbocharged 1.6 on moderate boost, with the thick disc tolerating repeated hard launches.

Why choose the thick disc over the thin disc?

The thick disc carries more friction material and heat capacity, so it fades less in long sessions and repeated launches. The thin disc revs more freely and fits the factory 1.6 flywheel. Both carry the same torque ratings from EXEDY.

Is the EXEDY Stage 2 Cerametallic Clutch harsh in a light car?

It is firmer than an organic clutch, and in a car as light as a Miata the engagement is noticeable. The sprung hub softens take-up, but a stock street car will be smoother on an organic disc. Turbo and track cars benefit most.

Description

EXEDY Stage 2 Cerametallic Clutch Kit for NA Mazda Miata 1.6L (Thick Disc)

EXEDY’s Stage 2 Cerametallic Clutch Kit for NA Mazda Miata 1.6L with the thick disc is built for the early Miata that is launched hard or driven in long track sessions, where heat capacity matters more than rotating mass. Turn 14 lists it for use with the later 1.8-liter Miata flywheel, and EXEDY rates it at 189 lb-ft at the flywheel on the 200 mm disc.

Design and Performance

The thick cerametallic disc gives the clutch more mass to absorb heat, which suits autocross runs and track days. A ductile-cast cover delivers 1,169 lb of clamp load on the 22-tooth, 24.3 mm spline for 237 lb-ft of clutch torque. Turn 14 notes the later 1.8-liter flywheel for this kit, a common swap on early cars.

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.
