On my son's miata, the wheel studs are just exactly long enough for the OEM wheels. He got a set of 1" spacers from somewhere that had integrated studs and bolt on using the original studs. It looks pretty good but he is also lowered on coilovers. It looks really good but in my opinion it is slower on the track now, and rubs. But he likes it
I don't know if his particular spacers would look good without the lowering.
