man u dun need it, i lowerd bout 6 cars already and each time i lowered, i used my own technique to uncompress and it aint even dangerous either. i put the spring shock combo up against a wall or somethign solid, then put a tire behind and have a friend step on the tire and then unscrew the nut. comes out no prob and no pop, too easy. but if u wanna be carefull, cant blame u.
