Will 10 inch wide wheels fit my Demon?

I use old 10" Centerlines with a 4.5" backspace, 28x10.5 Hoosiers slicks, I had to roll the quarter panel wheel lips for clearance, but the S/S springs are in the stock location (I flipped the front hangers to lower the ride height). I also use 275x60's street tires on those wheels, they look like they might fit without rolling the lip???
