Advice needed, Calipers hit spokes..

[XLexusTech]

So installed my calipers and rotors (GM 6 piston)..and they hit the spokes.
I guess I could send the Rims back and have them turned down but that may turn into a nightmare..
thinking about just using a 3/8 inch spacer and new longer wheel studs.
Would that be OK? I see lots of Corvette guys on the forums saying they do it.... (My car has c6 spindles)
i would trim the wheel lip if needed..

thanks for any advice.
