Can you believe it? The end of the week is getting closer. That’s right, Thursday has hit us straight in the face. With the end of the week announcing its arrival, we’re certain you are planning to work on your project this weekend. If so, maybe your plans have already been made? If those plans for spending some quality time in your garage include a little clutch work to your hot rod, you might want to check this out.

In this edition of Throwback Thursday, we’ve opened the Power Automedia vault, and are taking a short hop back to June 2010, to check out: Ten Questions with SPEC Clutch. This week’s throwback goes in-depth to answer some very confusing questions about what clutch is needed, and what materials will be best suited to particular applications.

Although a single-disc clutch is the normal fare for a street car, clutches can be built with multiple friction discs.

To get the answers, we reached out to SPEC Clutches and Flywheels. Based in Bessemer, Alabama, SPEC was founded by enthusiasts and racers who were motivated to build a better product than what was available to them. SPEC assembled a team of experienced engineers, clutch builders, machinists, and other automotive enthusiasts to build the company, which began cranking out clutches all-day in a 5,000 square-foot building.

Each SPEC clutch design undergoes rigorous testing.

In the original article, we take a deep dive into various clutch-disc materials, different clutch styles, and whether a single-, double- or triple-disc clutch is needed. We also get into what it takes to design a clutch that can withstand serious abuse and horsepower. Finally, Shelly Norton of SPEC highlights the proper way to “break-in” a new clutch to get many trouble-free miles.

The insight into the various clutch styles and materials is simple to understand, and you’ll have to check out the original article to get the full download about, Ten Questions with SPEC Clutch.
