I've read from a few folks that the rear is difficult to do without a lift due to the inability to get leverage.
Is there any reason the install can't be done by undoing the camber bolt rather than the control arm mount?
I came across this F80 install that uses the camber bolt method and it seems doable. I guess the downside is you are more likely to screw the camber, but you are going to need an alignment anyways in a few hundred miles.
Lastly - where are the "center" jack points on this vehicle? Obviously you can't jack up the car on the jacking points and get a jack stand in there at the same time.
Thanks folks!
