The idea of getting new wheels is to negate spacers, essentially buying wheels that fit properly in the first place (As many will tell you I found out the hard way, mainly for running brembos)
The Ad says if you have brembos, they won't fit. They may fit with spacers, but that's an expensive gamble...
My advice: Look else where - http://www.rimtuck.com/ study that site for 350z wheel sizes. No point buying wheels that will cause a lot of hassle to fit unless you will give up your life before you give up your wheels (Like I did )
