Will the EXEDY Stage 2 Cerametallic Clutch fit a 1993 RX-7 R1?

Yes. Turn 14 lists the 10953 for the 1993-1995 FD3S RX-7 in Base, R1, R2 and Touring form with the 13B-REW. All of them use the 236 mm disc size and 23-tooth, 26.4 mm input spline this clutch is built on.

Standard or HD thick disc for an FD?

The standard 10953 has 2,093 lb of clamp load and is rated at 320 lb-ft at the wheels. The HD 10953HD raises clamp load to 2,653 lb and the rating to 405 lb-ft. A big single-turbo FD needs the HD, while an upgraded sequential car is easier to drive on the standard kit.

How much power will the FD thick disc clutch hold?

EXEDY rates the 10953 at 400 lb-ft of torque capacity at the flywheel and 320 lb-ft at the wheels, from 2,093 lb of clamp load. That suits a 13B-REW with upgraded sequential turbos or a moderate single-turbo conversion on pump fuel.

Does it work with the EXEDY ZF01 flywheel?

Yes. Turn 14 notes that when the EXEDY ZF01 flywheel is used with this kit, adapter and counterweight N351-11-521 is required. The rotary relies on the flywheel counterweight for its balance, so do not install a lightweight flywheel without it.

Is the thick disc clutch comfortable on the street?

It is firmer than stock. The cerametallic disc grips quickly and can chatter on gentle starts, which the sprung hub of the EXEDY Stage 2 Cerametallic Clutch reduces. An FD used mainly on the road may be happier with the EXEDY Stage 1 organic kit.

Description

EXEDY Stage 2 Cerametallic Clutch Kit for FD3S Mazda RX-7 (Thick Disc)

EXEDY’s Stage 2 Cerametallic Clutch Kit for FD3S Mazda RX-7 with the thick disc is the choice for a 13B-REW that sees drag launches, autocross or long track sessions, where heat is what kills a clutch. The thick cerametallic disc and 2,093 lb of clamp load are rated at 400 lb-ft at the flywheel, enough for an FD on upgraded sequential turbos or a moderate single.

Design and Performance

EXEDY specifies a ductile-cast cover with 2,093 lb of clamp load and a thick cerametallic disc on the 23-tooth, 26.4 mm spline, for 501 lb-ft of clutch torque. The thicker disc absorbs more heat before fading, which is the deciding factor on a car launched repeatedly, and the sprung center damper protects the differential and half-shafts.

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.
