Having been in the Auto Repair business for most of my adult life I can safely say I've installed HUNDREDS of new clutches in cars.

I have never, I repeat, NEVER had to break-in a clutch. In fact, I have never seen nor heard of any "break-in proceedure". AND...I have never had a failure on a clutch I installed. Plus, I had absolutely NO control of how the owner drove the car so I think I can safely say each clutch was "broke in" in a variety of different ways for each one I installed.

Please tell me what the "propper break-in procedure" is for a clutch because quite franky, I've never seen nor heard of one.

Brakes? Absolutely. There is a break-in proceedure for Semi-metalic and Metalic brake pads, no question about it. But clutches? Never heard of it.

I also see that Springer said SAI installed his clutch so when someone blames the installer on his clutch failure, they're blaming Shelby American. And to be more than honest, it's real hard to F-up a clutch install. It either works or it doesn't (MOST of the time). I have seen one clutch install go bad because the tech didn't tighten the (diaphram type) pressure plate down evenly. He was a rookie Tech and that never happened a again.

Just like brake pads and rotors there is material transfer between the pressure plate, clutch discs and flywheel.
Maybe it's just me, but these are fairly expensive items and would rather do it right and have it last.
I never disputed that the clutch was installed improperly, only that not breaking it in correctly could cause issues.
I am surprised that with your experience you have "never seen nor heard of any "break-in procedure"
