I have an 89 yj. I have torn it down to the frame and built it back up with a chevy drivetrain d44/9". I keep kicking around the idea of running coil overs each and every day. I am at the point in my rig building process where I need to decide on what suspension to go with. I have only heard good things about coil overs. Right now I am converted to SOA. But, I would like to do something a bit different. If I decide to go with coil overs, how much would they cost? Should I just run them in the rear, and leafs in the front? What do you guys do out there? Just want to hear some opinions. Thanks!
