The fronts can be done by first releasing the two collars with the special wrench that comes with the kit. You turn then in opposite directions to release the pressure. You then turn the top ring that the coil spring sits on up until you get the desired height.
The rear should have a pod that the spring sits on. You would loosen the set screw and rotate the outer part to regain the height you need to clear the tires. You will not have to remove the center bolt or the spring but you will have to jack up the car and release the lower shock mount.
Once you get everything set, remember to bring the bottom collar up to the top one and tighten them up and retighten the rear set screw as well.
You can do this with a jack and jack stands.
