honestly i dont know, i had to use spacers for my rim to clear my coilovers before i had my brakes. so i am not sure, i wish i wasnt the only person who did this brake conversion so more people could field some of these questions. i wouldnt believe you would need them on the S14 because my stock rims will fit without spacers and not hit the brakes. it might be different with the S13s though.
