i have some koni yellow shocks, and i heard that you can adjust the perch setting to make the car sit higher or lower? ive had these shocks for about 5 months now and i just figured that out. now how do i change the perch setting? just take off the shock, move the perch, and will it lock there in place? right now its on the middle perch i believe, out of 5 perch settings. which way makes the car sit higher, which way makes the car sit lower? set the perch down lower for the car to sit higher? its way too low right now for winter driving, and i wanted to raise it up at least an inch or so. does it really make the car sit higher/lower noticeably?

thanks
