Who should buy the HD four puck EXEDY Stage 2 Cerametallic Clutch?

An owner of a big-turbo five-speed WRX, Forester XT or Baja Turbo used for drag launches or rally, where both maximum holding power and quick engagement matter. For a street car with similar power, the HD thick-disc 15950HD holds the same rating with smoother take-up.

How much power will this clutch hold?

EXEDY rates the 15950HDP4 at 463 lb-ft of torque capacity at the flywheel and 371 lb-ft at the wheels, with 583 lb-ft of clutch torque. That is the highest rating among the EXEDY Stage 2 kits for the five-speed GD cars.

Is it drivable on the street?

It can be driven, but it is harsh. The HD cover adds pedal effort and the four-puck disc grabs abruptly, so traffic and parking take care. Owners who drive the car daily usually prefer a full-face disc and keep the puck clutch for dedicated competition cars.

Does it fit the 9-2X Aero and Baja Turbo?

Yes. Turn 14 lists this EXEDY Stage 2 Cerametallic Clutch, the 15950HDP4, for the 2005 Saab 9-2X Aero and the 2004-2005 Baja Turbo, as well as the 2002-2005 Impreza WRX, the 2004-2005 Forester XT and the 1991-1994 Legacy Sport, all with five-speed manual gearboxes.

Will the stronger clutch break the five-speed gearbox?

A clutch that holds more lets more torque reach the gearbox, and the GD five-speed is the known weak point at high power. The clutch does not cause a failure, but owners at this level usually plan for gearbox strengthening or a swap.

Description

EXEDY Stage 2 Cerametallic Clutch Kit for GD Subaru Impreza WRX, Forester XT, Baja Turbo and Saab 9-2X Aero (HD 4 Puck Disc)

EXEDY’s Stage 2 Cerametallic Clutch Kit for GD Subaru Impreza WRX, Forester XT, Baja Turbo and Saab 9-2X Aero with the HD four-puck disc combines the strongest cover in EXEDY’s five-speed WRX range with the quickest-engaging disc. Rated at 463 lb-ft at the flywheel, it is meant for big-turbo GD cars that launch on slicks or contest stage rallies rather than commute.

Design and Performance

EXEDY rates the HD four-puck kit at 583 lb-ft of clutch torque and 463 lb-ft at the flywheel, against 527 and 420 for the standard four-puck 15950P4. The 230 mm disc and 24-tooth, 25.2 mm spline stay the same. The combination of higher clamp and a puck disc gives the most positive engagement of the group, and the most chatter at low speed.

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.
