I have yellows and the lowering springs I paired with them (eibach prokit/sportlines) gave the same drop front and back, so I used the lower shock perch on the front in those instances. When I got ground control coilover sleeves I could fine tune it all height-wise through those instead of having to mess with the perches. I have been running yellows with GC's a while now, no complaints.
