The only thing that bugs me a bit is that the rotors themselves are not fit over the wheel hub grooves and only the bolts are holding the rotor from moving. That's probably not a huge deal. To be honest I leave a set of rains mounted on my spare set so I don't use them often and would only use them in a rain race. I guess bottom line is I'll take a set of spacers. :) The rear wheel is the same correct? EDIT: I also just remembered I'll need to get a set of rotors as well, or move the rotors over from my other wheel if I need to swap them.
