Spec is very hit or miss. You either get a piece of garbage or a great clutch from them. There is no consistency in the quality of their stuff. You will hear from some who love Spec and you will hear from others who hate spec. With the stage one its pretty common to hate the Spec clutch kits. They just dont get it done. Regardless always use a Ford tob. the aftermarket guys try to slim the bearing up and use light weight stuff to try to save weight, but by doing so the bearing just dont hold up as well. The Ford ones are big, beefy, clunky, and last forever. They are "built Ford tough."
If you need to save money grab a new bearing and run that clutch into the ground. when it comes time for a new one look toward something more reliable like centerforce. Your only saving money if what you buy has the same lifespan as the expensive parts. Spec stage 1 does not last like a centerforce dual friction will.
