Need the experts to straighten me out.

I've looked over quite a few wheels & found some I liked, but it doesn't look like they will fit...or will they ?

The RS-GT 908 is 18x7.5 +45 & the RS-GT 901 is 18x9 +45.

What, besides them sticking a mile out of the fender will stop these from fitting?

Is it some thing to do with the brake caliper? I don't get it.

NEUSPEED crammed a 17x8.5 +40 under the back in the 8/01 issue of Sport Compact Car & it looked pretty damn good !!!!

Any help? I REALLY want these wheels !!!

Oh yeah, you'll only find them on the bbs-japan website, so, how do I get them?
