How much more does the HD EXEDY Stage 2 Cerametallic Clutch hold on a WRX?

EXEDY rates the 15950HD at 371 lb-ft of torque capacity at the wheels against 336 lb-ft for the standard 15950, with clamp load rising from 2,315 to 2,536 lb. Flywheel torque moves from 420 to 463 lb-ft on the same disc and spline.

Who needs the HD WRX clutch?

A five-speed WRX, Forester XT or Baja Turbo with a larger turbo, an EJ257 swap or aggressive launch use, where the standard kit would be near its limit. A lightly modified car is easier to drive on the standard 15950.

Will the HD clutch protect the five-speed gearbox?

No clutch makes the gearbox stronger. The HD kit holds more torque, so more of it reaches the five-speed, which is known to be the weak point on high-power GD cars. Owners at this level often budget for gearbox upgrades as well.

Does the HD version fit the Saab 9-2X Aero?

Yes. Turn 14 lists this EXEDY Stage 2 Cerametallic Clutch, the 15950HD, for the 2005 Saab 9-2X Aero, which shares the WRX drivetrain, along with the 2002-2005 Impreza WRX, the 2004-2005 Forester XT and Baja Turbo and the 1991-1994 Legacy Sport.

Is the HD clutch much heavier to drive?

Only a little. Clamp load rises by about 220 lb over the standard kit, so pedal effort increases slightly. Engagement character is set by the thick cerametallic disc and sprung hub, which are the same on both versions, so the HD kit drives much like the standard one.

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

EXEDY’s Stage 2 Cerametallic Clutch Kit for GD Subaru Impreza WRX, Forester XT, Baja Turbo and Saab 9-2X Aero in HD form raises clamp load to 2,536 lb for the EJ turbo car running a big turbo or an EJ257 swap on the five-speed. EXEDY rates it at 463 lb-ft at the flywheel, on the same 230 mm thick disc and spline as the standard kit.

Design and Performance

Against the standard 15950, the HD cover moves clamp load from 2,315 to 2,536 lb, clutch torque from 527 to 583 lb-ft and flywheel torque from 420 to 463 lb-ft, by EXEDY figures. Disc size and spline are unchanged. The step is modest, so pedal effort rises only a little, while the extra margin helps a car that has outgrown the standard rating.

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.
