nah fuck that, just use the S13 bolts and tighten them down alot. haha
J30 rears will work.... BUT... the hub is a press in, not bolt in so you have to use the entire knuckle. but then you have to play with your shocks bc the J30 has a different lower shock mount that the S13. its similar to the S14, but not quite the same. and we all know how bad S14 rear shocks fit onto S13s.
