the costs of the pss9 are € 1.400,00 here in austria. exlusive the costs of installing. i love the suspension. i can drop it as i want and can turn it from very hard to little hard. also if i want to change my wheels or tires i can react and drop it or higher it.Split said:it looks like the drop you'd get from just putting in H&R Sport Springs, i believe its 1.2Inch in the front, 0.5Inch in the back. VERY nice. how much did you pay for those bilstein psg9's and where did you buy 'em? I want a pair too.
