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.

Finally, Shelly Norton of SPEC highlights the proper way to “break-in” a new clutch to get many trouble-free miles.
