Hello everyone, I just ordered s12w calipers, 84 300zx rotors, 1 inch wilwood master cylinder, and hub spacers from silvermine motors for my 73 240z. I have 14x7 mesh wheels. Well my concern/question is if I will need a wheel spacer? I would like to get the spacers now if I need them rather than wait until I already have everything going together and get held back. Any help or information would be greatly appreciated. Thanks
