Well since this is your thread I guess I will post here. If you plan on installing OME (old man emu) springs, you will be cranking the torsion bars to match the lift in rear from OME springs. Cranking the torsion bars increases the angle of CV's which makes them more prone to breaking. The way I somewhat fixed it was by installing a 1.5" differential drop bracket (from Darlington offroad) which drops your differential and in turn staightens out your CV's. I will get a pic sometime of the other VXers CV angle compared to mine, but they were amazed at how much straighter they are with only a 1.5" drop. The only reason you really flip your ball joints it for easier alignment and extra 1/2" down travel. But it doesn't take much to do it.
The differential drop brackets takes a LOT to install, very spendy ($750+ installed), but for me not to break $900 CV's it's worth it. Unless you drive hard or go offroad this really isn't necessary as the CV's will mostly only break when stressed hard at awkward angles. Of course I even managed to break them at stock height, but I think I'm the only one....
I also installed a 1" spring spacer which adds an extra inch of lift in which you also need to crank the torsion bar an extra inch (to match). So the OME springs lift it 2.5" and the spacer adds 1", that is 3.5" of lift (front should match by cranking torsion bars) and then my front diff is dropped 1.5". So in other words my CV's are at an angle of the torsion bar being cranked 2" when really it is cranked 3.5".
I tried to make that as easiliy understandable as possible but let me know if you have more questions.
