So I want to do a 5 lug swap on my 89 s13 to give me better wheel options. I got a guy who sold me the J30 front hubs with the s13 bearing pushed in and the rear NA Z32 hubs. I have done a lot of internet searching and can't come up with the answer to these questions. Can I use my stock calipers with this swap? What rotors am I going to need to get? Do I need to do anything other than just swap the hubs out. Any help would be super appreciated. Thanks.
