Fair enough and good info. So it's really on StopTech for fastener selection. And being someone who picks fasteners for things from time to time I'd imagine they had their reasons.
But in the case of a $6000 brake kit, if I were StopTech, I'd probably have said 'sorry' and sent some new hardware because it would be good customer service and good PR.
