OK, since nobody else asked it, I'll ask...
By shaving 1/8" off the caliper, what have you done to the structural integrity of the caliper? It was designed and manufactured by Toyota to a certain thickness for that particular metal for a reason. If it was meant to be 1/8" thinner, don't you think Toyota would have done that? They are pouring extra metal (= more money) with each caliper they need to manufacture. Maybe with a stronger metal composition, they could make a thinner/lighter caliper, but that is what aftermarket parts are intended to do. IMHO you just created a major stress/breakage point on the OEM caliper. I'm glad that you found a "solution" to get your Highlander wheels to work, but I would never jeopardize the safety of my family by messing around with something like grinding down brake calipers.
Somebody please tell me that I am overthinking this issue.
