Get rid of Eibach Drag Springs and go to ? rear springs.

[R3_82GT]

My car came with Eibach rear drag springs, and I'm not happy about the ride, it its a little crooked, and the tires rub. I think I want to go with a new set of Stock GT springs (They are about 60 bucks shipped from RockAuto). I can't really go too low as I have 8.5" Centerlines with a 255/60-15 tire. I figure I can always cut the stprings a little if it sits too high. Would this work pretty good or does anyone else have any suggestions?

Car is really just for cruising and ocassional trips to Kennedale
