I literally have like 5 miles on my car with the Clutchnet clutch I got, so longevity I cannot speak for... however.... this has been the only non-oem clutch i have EVER been happy with right off the bat. I just did a aftermarket clutch in my Audi that thing sucked so hard (as usual) for the first 1,000 miles. Clutchnet is awesome, I hear nothing but good things which is why I went with them.o
Notice the Raybestos clutch material in that pic above^^ They use quality parts.
