Raising the rear.
Instead of rubber pads use steel plate with a hole in the middle. Make them like big washers. As to who gives a F**K about the wheel/spring rate, how many people think their E30.s are sprung stiffer at the rear than the front. Almost every RWD sedan I know of is sprung stiffer at the front. An E30 with 400# rear springs has an effective rear rate of about 250#.
