I'm running the stock 95 brake setup, with 16' Pony's right now. I wouldn't think switching to a 15' Prostar would have clearance issues?I saw some Summit knock offs of the CCW style drag rims. I think those are a better buy than the ProStars. They are a little more money than the Weld knock offs, but they don't have any clearance issues with the brakes.
