coilover wrenches are coilover wrenches.
im sure someone has a pair theyd let you borrow.

just loosen the collars, and turn them up to raise the car, or down to lower.
and tighten the collars back.
if all else fails, if theres two collars, loosen the bottom one by hammering a recess with a screwdriver, and turn the collars with chanel locks.
