theres i big difference between a standard patrol height and a soa patrol. They do like to roll, take it from me had a few mates go over with this mod.
Obviously wider offset wheels will help with the stability of your Patrol. My Patrol is SOA 35's, dont have a problem with it rolling, (yet) still get awesome flex for leafs. I do notice when i accelerate though, it wants to swerve to the right a little. Mine is only off road use, would take a lot more to make it steer properly and make it safe.
has anyone put there leaf springs over there diff for extra height i am thinking of doing it but am unsure what needs to be done any info or pics would be great
