My coil overs yet is because I work a half and hour a way in Riveria beach I have no other mode of transportation and from my understanding it's 6 hours to get them all set to the correct ride height. I would have my friend do it but he said it's a pain in the ass to get them all set.......he's only 10 minutes from where I work but there's a catch he might not be able to give me a ride back to work. also I don't think he could be there at 7:15 in the morning to meet me all thought I haven't asked him, I really need to do them because all my shocks and struts have been blown out.
