Custom cars have many suspension options, but one of the more popular ones is a coilover. It replaces the existing shock and coil combination with an adjustable spring. It's easy to adjust, and means that the driver can adjust the height of their vehicle for show or for better performance. In this example, we're going to adjust the coilovers on a 1995 Honda Accord, but the process is the same for all vehicles.
Measure from the floor to the top of the fender lip using the tape measure. Adjusting coilovers can involve a bit of trial and error, so by having this original measurement, you can find out how much exactly you've gone up or down, depending on your needs.
Lift the vehicle using the jack and place it on jackstands. Be sure the vehicle is secure and that the tires are at full droop.
Use the two adjusting wrenches provided in the kit so that you break loose the bottom nut of the coilover. This is the nut that keeps everything tight and secure, and prevents the coilover from adjusting on its own. Loosen that bottom nut several turns down, just to give you freedom to work on the other nut.
Turn the top adjusting note up or down depending on your need. In this case, we're going to lower the vehicle, so we're going to turn it counterclockwise to drop it down. As previously noted, this involves a bit of trial and error, so you may have to repeat this step, but try to be as consistent as possible between each side-to-side adjustment.
Tighten the bottom nut back up onto the top nut, keeping the two secure against each other. Repeat the process on the opposite side of the vehicle.
Lower the vehicle off of the jack stands and measure your results. If you need to move it up or down to make the vehicle level, just repeat the process in smaller increments.
