how so, and every failure no matter the company or component must take alot into consideration as to what happened, especially a clutch. Its all too easy for some meathead putting a 300ftq clutch behind a 500tw VR6 turbo vw, who cheaped out on the clutch, probably the install too, was spec’d (no pun intended) wrong for the app and might not be able to drive all to well either for one to let go, post some pics and a “I HATE SPEC” thread on vortex and then all the euro sheep jump on the bandwagon.
Improper design for the build, improper use, contamination, improper install and/or unmatched flywheel for the PP&disk, quality control failures.
IMO thats the order of most probable to least probable for what caused ANY clutch to fail.
