the fronts seems to be the same but the rears are a different setup at the bottom, but I've heard that you can change the setup on your car to suit but you better ask a suspension place to make sure.
from memory i dont think they are. those ones look good but make sure you dont park to close to the gutter as they are eaisly scratched (cause the spokes come outwards)
nothing for an r32 at the moment, actually i might have something off a 180sx (not sure if it would fit though).
I think the Jap rims look alot better.
