Tires fall off not good i do see your point though.But then again i have never seen anyone use nylock on the ball joints thats a castle nuts job.And requires a vigalient inspection which no one ever dose.But just the same youve taken your blame like a man.as far as the grinding and all i guess that would suck.But to be honeswt you should never buy powdercoated swing arms and a-arms due to the fact these are after maket race accessorys and often do require some minor adjusting After you have fitted them to your bike then powdercoat them.As far as the poor customer service and poor workmanship on the carrier bearing and lack of customer skills shame on you EPIC.Answer your phone and stroke me don't ignore me.
