it should last, depending on how you drive. My stocker lasted with the smarty and comp together for about 6 months, and i wasn't always nice to it. however, i think it also depends on how the clutch has been treated in the past. i know some guys stock clutch wouldn't hold up to the comp by itself. If you do any heavy pulling i would be sure to turn down the EZ and you should be fine until you upgrade your clutch.
