Well, first things first. This is a replacement clutch that will actually work if you order it to match your engine type and code. That being said, I'm not sure what exactly makes this clutch assembly "high performance" because from what I've noticed about this particular package I don't see anything that differs significantly from a similarly styled standard clutch assembly, except for a few red vario bushings and black rollers. In my experience there is absolutely no improvement in rear clutch assembly performance. The entire rear clutch assembly, including clutch facings, internal springs and torsion spring, is completely stock based on my comparison to three other exact spec worn clutch assemblies. Still, it works when you need a working clutch replacement but don't expect to get something overtly "high performance".
