R32 GTR calipers w/ alternate rotors

[guitaraholic]

I was told on Fresh Alloy that 2003 Altima rotors work with R32 GTR calipers. Here is the measurement for the both of them

R32 GTR 296 x 30
Altima 296 x 25

I was told the IS300 calipers work with a 3mm spacer, but then I discovered that the hub diameter doesn't match. I believe the Nissans is 60mm while the Lexus is at 48 or so, so even though the rotor diameter and thickniss is almost right on, I don't think it will fit.

Right now I have on Z32 rotors and the pad is not fully swept, so when I change pads, I am going to change rotors too. Plus I was looking for somewhere I can do it on the cheap, and not have to special order them.
