I would think staggered wheels would work fine with a higher hp miata, but I'm not gonna be the one to try it out. They definitely aren't just a MR thing, most FR "sports cars" come with staggered wheels; S2000, 350z, Corvettes, Vipers, and every ///M car since the E36 have all come staggered.

Is there a reason that an 8 inch wheel (or even 9 inch) is better than a 7 inch for 225s? A lot of the S2000 guys run 225's on a 6.5 inch wheel, although they are a tight squeeze, I never had any problems wit it. I just assumed a 7 inch wheel would be sufficient. I hear so many people talking about how sensative our cars are to unsprung weight I was trying to keep as much off of it as possible.
A 225 is an 8.85" wide tire. There's been testing by a vendor here (949) that I saw awhile ago that supports that theory that the wider wheel will result in a stiffer sidewall, better cornering, etc. Unsprung weight really isn't an issue when some 15x8s and 15x9s are 12 and 14 lbs respectively and the miata has 200-300 rwhp. I think ultimately it comes down to what your using the car for (autoX, DD, track, etc) and what kind of rwhp your pushing. I personally have been in a 230-250 rwhp miata on 195s and ended up on a telephone pole.

Awesome reply, thanks for the info, I'll definitely look for some 15x8's. I've never been up a telephone pole, but I've gone through a light pole and I have to say, I'm not a fan.
