Which cars does the Copper Clutch Set for VAF fit?

Cusco USA lists part number 667 022 F for the Subaru WRX STI (VAF, 2015-2021), the Subaru Impreza WRX STI Sedan (GVB, GVF, 2011-2014) and the Subaru Impreza WRX STI Hatchback (GRB, GRF, 2008-2014), plus the other cars listed under Applications. The Copper Clutch Set for VAF replaces the factory clutch, so the transmission has to come out to fit it. Check the model and gearbox against the Applications list before ordering.

Will it hold more power than the factory clutch?

Yes. Cusco builds this clutch to hold more torque than the factory part, through a stronger cover and a performance disc. How much more depends on the engine, the tune and how the car is driven, so match the clutch to the power level and use rather than buying the strongest option by default.

Is it suitable for daily driving?

Yes, for most owners. The reinforced cover makes the pedal a little heavier and the engagement firmer than the factory clutch, which most drivers adapt to quickly. A car that spends most of its time in heavy traffic should be matched to the least aggressive option that holds its power.

Is there a break-in period?

Yes. Any new clutch needs time for the disc and the pressure plate to bed in against each other before full clamping is reached. Drive gently for the first few hundred miles, avoid hard launches and high-rpm shifts, and follow the bedding guidance supplied with the clutch or from the installer.

What else should be replaced at the same time?

With the transmission out, it is worth inspecting the flywheel and resurfacing or replacing it, and fitting a new release bearing and pilot bearing where the car uses one. On a track car, a lighter flywheel can go in at the same time.

Description

Cusco Copper Clutch Set for VAF Subaru WRX STI, Impreza WRX STI and Legacy / Outback

Cusco’s Copper Clutch Set for VAF Subaru WRX STI, Impreza WRX STI and Legacy / Outback pairs a copper clutch disc with Cusco’s reinforced clutch cover, as a direct replacement for the factory clutch. The reinforced cover adds clamping force so the clutch can hold more torque than stock, and the copper disc is built to take more heat than a factory organic disc. It suits a tuned car that has started to slip the factory clutch, or a car that sees repeated launches and track sessions.

Design and Performance

A clutch slips when the torque coming through the flywheel exceeds the friction the disc can hold, and the friction it can hold depends on the clamping force of the cover and the material of the disc. The Copper Clutch Set for VAF raises both against the factory parts. Friction materials like this typically engage more firmly than an organic disc, so the pedal and take-up feel different from stock; most owners adapt quickly, but a car that only commutes in heavy traffic may be happier with less aggressive parts.

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.
