Simple statics calcs will tell you the farther out the rims are, the more moment you'll get. Plus you have 2 shear planes to deal with. I'm sure they were well within the tolerances, but I couldn't shake the thought so I removed them and ordered new wheels. As far as brand, the BMS spacers were great and came with extended bolts to maintain the proper thread engagement.
You are right. You probably were rubbing. The LCI's have much less clearance. The OP and I have pre LCI cars.
