Well you CAN adjust camber and toe a little but its not easy. You have to torch the top of the housing and let it cool to create negative camber, since the metal will cool more densely than it was origionally. You can do toe the same way. The trouble is that you can't really undo camber or toe that easily...

Live axle setups can have a very predictable breakaway, unlike some imperfect IRS systems.

Matt is totally right about the steering angle on the mustangs as well.

Why swap in an SR when the 2.3t can make plenty of power on its own?
