Tire size on a dropped capri.

Hey guys. I've got an '86 capri and I'm buying a set of rear tires today. I've got 235-60-15's on turbines. (7 wide). Everytime I go up an embankment, turn up or down a driveway or maneuver a speed bump the sidewall rubs on my quarter panel. What size can I go down to? I've got 215-60-15's up front. Stock lower's, after market upper control arms. Red drop springs... not sure of the brand. I think about 2 inches. Need help/advice with a size that'll not rub but still not be too narrow.

Thanks,
Joshua
