Pro's and Con's of 7" rims up front

What are you running now? I am running 15x6 with 205/70/15 up front on my duster, car drives nice no complaints.

I'm running 14" BBP rims with E70/14's (205/70/14) Bias Ply red lines, they were on the car when I bought it. Absolutely hate the way it handles with the Bias Ply tires. I was hoping to put the Cragar 510 series Mags on but Cragar discontinued the 15X6 wheel I can only get 15X7's. Would love to put 15X8's on the back but might have a clearance issue with the stock rear suspension. 68 and 69 Darts don't have the clearance that the 70 and up A bodies do in the rear. I have a set of Wheel Vintiques 500 Mag wheels 15X6's and 15X7's on order with Summit but delivery keeps getting pushed back.
