I'm upgrading to 30mm z32 calipers and rotors. i'm retaining the 4x114.3 lug pattern. The front calipers bolt right on but the only write up i found did a 5 lug conversion on the rear (yeah retarded when the front was 4 lug) anyways. he didnt explain if the rear caliper bolts up on the stock s13 hub. if anybody can help, post away. if you dont have anything useful, don't post please.
