Yea, I dont see a reason why they won't fit either. Those wheels are a little more expensive than the Axis Hiro's and go for around 375 a piece. Heres a link with some different colors:http://www.240sxmotoring.com/grgudibygrus.html.
Im pretty sure they'll fit really nice for that agressive look. Go for it! I was thinking of doing 18x8.5 +35 on my MS3 with the Gravity Gullflames.
Its not going to be too much like the 18x9's and I think they're the perfect size.
