Lookin at a wider stance, looks I guess, plus its that much easier to do my 300zx brake conversion. Problem is, i'm not familiar with spacers and studs and all that. First are the ones that you hammer out and change in longer studs. Do you have to press in the new ones at a machine shop or something? Then there are the H&R spacers that aparently fit right over your existing hub and have longer studs on them. Anyone used these? I'm wanting to get 20mm for the front and 25mm for the back. for pressing and getting new tuner lugs, this might actually work out the same price (have calulated but i'm guest-a-mating that they'll be close). Are the H&R spacers the same OEM thread style? How about Nismo, Peak Performance, or APR?
