I have a few questions. Does anyone know what the spring rate and dimensions of the front and rear springs are on the WRX? I want to upgrade to a stiffer spring but I don't really care about lowering the car. All of the springs that i have found will lower the car at least 1.5 inches and most don't give a spring rate. If I have the spring rate and dimensions I should be able to find a set or peice together a set that will suit my needs. For those of you that have changed the springs what brand did you install and what was your reason for changing them?
