actually you don't even need the spring compressor. I honestly have never seen a spring compressor small enough to fit on honda springs!!! I've lowered about 7 hondas and the fastest procedure is to just undue all the bolts but leave the 3 strut mount bolts on top. Then unscrew the actual nut holding the strut rod to the mount last. It shoots out with some force, but not like at 100mph that everybody claims it does. You don't have to follow my advise but I've replaced all 4 springs and lowered down the jack in about an hour!!!! Try to beat that time.
