Mine didn't make a sound either after I put the stocks back on. I would just remove the caliper and rotor just to make sure, pretty easy to do. Like 2 bolts hold the caliper and one torx holds the rotor. I tried 20mm spacers and they cleared but my wheels would clunk on a turn, so I went down to 15mm spacers and solved the problem. Still have the 20 mm spacers if that's the size you need.
