It will cause it to ride a little stiffer and it will increase the angles on your ball joints. Overall its not that bad though. There is no way to get around your ball joint angles unless you go to a full suspension lift. The one the you MUST do is get an alignment done after you make the adjustment or it will eat up your tires.

I was thinking about what you advised earlier, and had one question - would cranking my torsion bars cause it to ride much stiffer/be bad for it?
