Will the EXEDY Stage 2 Cerametallic Clutch fit a 2004 WRX?

Yes. Turn 14 lists the 15900 for the 2002-2005 Impreza WRX with the 2.0-liter turbo and five-speed gearbox, along with the 2004-2005 Forester XT and Baja Turbo, the 2005 Saab 9-2X Aero and the 1991-1994 Legacy Sport. All share the 230 mm disc and 24-tooth spline.

Thin or thick disc for a WRX?

EXEDY rates the thin-disc 15900 and the thick-disc 15950 the same, at 420 lb-ft at the flywheel and 336 lb-ft at the wheels. The thin disc revs more freely, while the thick disc absorbs more heat for launches and rally-cross. The HD versions raise the rating further.

How much power will the WRX thin disc clutch hold?

EXEDY rates the 15900 at 420 lb-ft of torque capacity at the flywheel and 336 lb-ft at the wheels, from 2,315 lb of clamp load. That suits an EJ205 or EJ255 with a larger turbo, fuel upgrades and a tune.

Does it fit the STI six-speed?

No. The WRX STI uses a larger 240 mm pull-type clutch for its six-speed gearbox, so this 230 mm kit does not apply. EXEDY covers the STI with the 15951 family of Stage 2 kits, including thick-disc, four-puck and HD versions.

Is a cerametallic clutch hard to drive on a Forester XT?

It is firmer than stock and can chatter when pulling away gently, which the sprung hub reduces. A Forester XT that tows or sees rally-cross benefits from the heat resistance of the EXEDY Stage 2 Cerametallic Clutch, while a stock commuter may prefer an organic disc.

Description

EXEDY Stage 2 Cerametallic Clutch Kit for GD Subaru Impreza WRX, Forester XT, Baja Turbo and Saab 9-2X Aero (Thin Disc)

EXEDY’s Stage 2 Cerametallic Clutch Kit for GD Subaru Impreza WRX, Forester XT, Baja Turbo and Saab 9-2X Aero with the thin disc gives the five-speed EJ turbo cars a cerametallic clutch that keeps rotating mass low. EXEDY rates it at 420 lb-ft at the flywheel, which covers a WRX on a larger turbo and tune and a Forester XT that tows or sees rally-cross.

Design and Performance

A ductile-cast cover applies 2,315 lb of clamp load to a 230 mm thin cerametallic disc on the 24-tooth, 25.2 mm spline, for 527 lb-ft of clutch torque by EXEDY figures. The thin disc lets the boxer rev quickly between shifts. It shares its ratings with the thick-disc 15950, which trades that low inertia for more heat capacity.

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.
