No spacers...no clearance issuesWilwood 6-piston superlight kit from ArizonaZcar Don't know what the size comparison is between Wilwood and Stoptech calipers...however, the tight fit with stock set-up is irrelevant. When you increase the rotor size and relocate the caliper to fit the rotor, it moves the entire brake assembly away from the center of the rim at the spokes where it's tight. The new position of the caliper lines up with a section of the rim spokes that allows more space to fit everything (i.e) -the rim spokes gradually get more concave as they travel from the lip to the center. When I tried to fit the same RPF1's up front with the stock set-up...it wouldnt clear, so I understand the 5mm spacer. After the upgrade, it cleared without any issues. You shouldnt need the spacers with your new set-up...at least that's my hypothesis.
