Decent handling susp setup?

Yeah there are pretty much none, at least for DOT, street legal tires. There are some race only tires out there in 15", but again selection is very limited. It's actually more of an issue with the other Mopar body styles though. On an A-body to get a good sized tire up front you pretty much need an 18" rim anyway because of the outer tie rod end clearance.

What If I were to cave in a bit and go with a 17, Bummed out because I really wanted to keep my dog dish caps but after the last few days of trying to find a decent set of 15 tires I'm about ready to switch to a bigger wheel. It would be cool If I could get a 17 inch wheel that would accept my dog dishes but I don't think a wheel exists. Cragar makes a black D window wheel in a 17. They have 8 and 9 inch wide available both with 4.5 backspacing.

I know 18 would be better yet and I know I shouldn't be soo worried about aesthetics especially when the goal is better handling but I really just don't care for the way 18's look on my car. I just think they look too big. Honestly the only 18 inch wheels I thought looked ok on an abody are the enkei wheels you have on your duster, Don't know why but look more like 17's to me.

Assuming I do get those Cragar 17's whats the largest I can fit up front and in the rear with stock wheel wells? 255/50?
