char1ie....just the cheaper coilovers fella, mine only adjust height and stiffness.....as for spring rates.....think mine are 330 (ish) on the front and 180 on the back.....so the front is set on "full soft" (too hard) and i have to stiffen the back up to match the front a bit, other wise it wobbles like fook along the road......i need softer front springs......
