if this was an option to me at the time of my purchase....i would have selected the h&r cup kit combo.

i think the eibach springs are too soft in the rear for my preference (the car squats too much in the rear under acceleration). the cup kit is stiffer than my set up...but this would solve my issue. the quality of a cup kit is excellent...i used to sell them in the past when i was a sales manager for tc kline racing (they specialize in bmw racing).

$695 at the tire rack...go for it! (see link below)
