dont rent this spring compressor from autozone!

ya, its free.. but it scratched the hell out of my eibachs!!.. worked fine for dissassembling my oem coils, but after compressing the new eibachs and installing the 5100's at 0... i couldnt get remove the hooks from between the coil... normally the threaded rod unscrews from one end, but it was stripped.. the gap between the coil on the eibachs is smaller and the hooks on the tool are too fat.. i had to spin the tool all the way toward the bottmom of the spring and there is 1 spot where they barely can pop out of... no way it would have come out if i set the shock higher than zero...wtf
