s14 front hubs use a 32mm pinch bolt. if yours weren't pinched then maybe the previous owner had 5 lugs hubs and swapped in the 4 luggers when they sold you the car (who knows). i bought a set of front hubs from ebay, and they barely lasted a year. got a new pair of OE hub from ray at westco nissan for about 45 bucks more.
so just get the OE hubs for the front
