Re: Stock 6" 3 nub wheels on 12" CPP disc brakes?

I figure GM puts a little extra fat on as liability insurance. Their quality is a good bit higher than 'just enough'. It all depends on how much is needed off. Grinding a little off isn't going to cause some catastrophic failure. If it's along the radius in the center, that is high from being at the casting seam. I'm curious to know the details.
