Offset wise, thickness wise...yes, exactly the same.
But, you would need to modify your current calipers to allow the larger diameter. I have R33 GTST calipers as well, and the disc just hits the entry and exit points. Easily modifiable, I just can't be arsed doing it. I am certain there is an article about it on here.
You would need a 15mm radius spacer for the calipers to run right on this disc. Once again, an easy thing to get.
