SA/FB/Old School/4x110 guys help!

[P71]

205/50/15 is the super-awesome autocross/road race tire size for Miata's and Civic's. So I can get Falken Azenis Rt-615's (basically the closest you can get to an R-Compound without being an R-Compound) for $72 each. Why go to a 215 or a staggered setup when those class of tires in a 205 is more grip then the 12A can even handle? A 205 is still an 11% increase over a 185 on contact patch!

Remember, for hard cornering you want the widest rim you can get the tire to fit on with out "stretching" to have a nice 90* sidewall with no balloon. A 15x8" wheel with a 205 tire is a perfect match for that. And again, the whole $$$ comes into play. If I had serious cash I'd do an FC 5-lug brake conversion and go from there, but sticking with a cheaper class limits me to stock size/style rotors (but they can be slotted/better made) and to whatever I can get to stay on there.
