not sure what the offset on the r34 gtr wheels are, but the r33's (also 9") was 30mm which made them stick out nearly a cm too much at the front end of a gts25t, the rears sat flush with the outer surface of the guards... there's a set of volk challenges 17x8 et30, 17x9 et38, at powerplay, which will fit a gts25t nicely but at $3.5k that's way outta my budget...
