I know some folks have been using aftermarket wheels and also some aftermarket calipers on their NSXs, and they sometimes have problems with the wheels coming into contact with the calipers or the suspension components. One solution that may work are wheel spacers. These are flat disks that fit between the wheels and the hub, and they move the wheel out ever so slightly.
I bought two different sets of these from R&S Racing, one set that's 1/8" thick and another that's 3/16" thick, but I never used them.
