I was just gonna suggest that. If youre just doing it for the brakes, the itr conversion is just a waste of money... You can get a real 4-piston/floating rotor 11.5" brake kit for half the money... probably twice the function.
Either fastbrakes 4-pot upgrade for the fronts, or Willwood's big brake kit (available for like $600 thru Summit) are much better brakes for the money.
to me, the only reason anybody would want the 5lug conversion is for bling, as far as a brake upgrade its just about the worst bang/buck you can buy.
