They'll fit in front, but not in back. They really slow the car down though. Gearing is much taller, you can really tell the tires are bigger.

Traction is fine with 205's especially if you go with 7-8 inch wide wheels. The wider the better.

The 215/45/16 Azenis also fits, but is still taller than stock and only .1 in wider than the 205/50/15 Azenis, hardly worth the gearing penalty.
