Ixlr, In Wilwood, the smallest big brake setup that gives the necessary rotor width and hat offset is a 10.75" diameter rotor. With Dynapro or Dynalite calipers, the O.D. of your caliper is 12.86", a pretty tight to fit into a 15" wheel. Depending on the caliper pocket design of your wheels, this may or may not work, and I do not know if 10.5" is considered big brakes, but this is the smallest of your options and it may be too big. Also, that rotor uses the small and rare 6x6.25" bolt circle so your only hat option comes undrilled. There are smaller diameter rotors, but their .75 width is incorrect for any decent type of caliper, you loose any possibility of a parking brake, and the hats are non-existent.
