Decent handling susp setup?

Yep, it's been mentioned a few times now. That's what I had on the car but I'm going to totally different route now that I'm actually trying to get the car to handle. Wish there were more 15 inch performance tire options just to appease the musclecar guys

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.
