Well, I think that the smartest thing I've done so far is posting my question here.
Getting some varies opinions, and I'm soaking every one us like a sponge .... well, to the best of my ability anyway.
I'm going to stick with the OEM 7" rims & 215's until I become familiar with how she handles. I'll start exploring later.
That'll also allow me some time to read-up on caster, camber, and toe-in and -out. Even though I've been a lifetime gearhead (yeah, going back to the 60's!!! ... I'm an old fart), I know very little on car handling dynamics. Never too old to learn.
Thanks again to everyone who contributed.
