well friend on mine has some s13 spindles that I am going to put a set of J30 hubs onto. s13 has 4 lug hubs and i got a set of struts from pull a part off a J30. next step is finding some front coilovers for either s13 or s14.
also i might have to swap ball joints since the s13 uses a smaller diameter ball joint. thinking of just taking the spindles to pull a part and trying them on the j30 i pulled the struts off of.
