Coilover ride height changed after new rear subframe??

That's really strange. Are you sure they didn't change the coilovers? If you're 100% sure that the coilover settings aren't changed, then I'd agree with MattP that it must be because of the bushings. A whole inch is an awful lot of discrepancy, though.

I haven't looked at the 370Z rear subframe, but on most cars there's 4 studs that are part of the body of the car that the subframe slides onto. Large nuts hold the subframe to the car. I've had a few instances where the subframe isn't lined up completely correct and ends up not being seated totally flush, which means you have to pull the subframe back out and try again. The subframe seems tight because it's kinda wedged in there. Happened to me twice on my own 240SX. Double check that you're not having that issue. If all else fails, take it back to the shop and ask them why it's not right.
