I just got my new ground control sleeves and I am ready to install them. My question is how do I adjust my height after I install them as well as in the future if I need to lower or raise it... Thanks

 

To adjust height, you might have to jack your car up and put your arm behind the wheel. Turn your adjustable spring perch. I don't know if there is a standard way of measuring height. I just use a ruler and make my drop or raise the same on both sides using a measurement on the ruler as a point of reference.
