when i installed my prokit/yellows, i used the top perch all around. now i think i want to lower it to the lower perch in front and middle in the rear. however, when i started to do this, the spring didn't "fill up" the expanded shock (even with the spring compressor totally off). this worried me b/c i don't want my spring "falling out" of the top cap and banging around loosely when the car is on a lift or when i lift a wheel autoxing. if that happens, i'm nervous that it won't go back in right.

here's my question: i know a lot of people use this set up, and i know a lot of them use the lower spring perches, so how do you account for the mismatch in prokit length and expanded koni length.
