Tire size/type ideas?

Then I wouldnt raise the back, just go with stock height springs and crank the torsion bars up front down 1" and use 17" rims. Tire size I cant help with but I know 245 is the widest back tire you will fit with no mods.
I was planning on raising the front and back just an inch or so with new springs, not just the back since thats mainly used for racing and im going for a cruise car look. The big body of the car so low to the ground just looks a little off IMO. I think I might settle with the 15 inch tires, and thank you for the advice!
