I'm pretty sure the LCAs were mostly responsible since they're made of 7075 Aluminum and are a LOT stiffer than the stock steel ones and thus transfer much more force from the shocks to the wheel studs when the stock ones would have flexed slightly and absorbed some of that force.
My factory studs were okay so thankfully I was able to just remove the spacers and bolt the wheels back on.
TLDR, Stiffer LCAs and aftermarket suspension parts will put a lot more shear stress on the studs. Don't use spacers at the track.

I would highly doubt the different RLCA has anything to do with the stud failing. I've heard more stories than I can count on bolt on spacers having issues.
