Why we beating up a brother? When I rebuilt my 4-bolt cv axles and did the m2 short shaft conversion, I flipped my cages. Flipping the cages shortened my axles an additional 1/8" (I measured). So, I'm confirming what JMortensen said above. If you are autocrossing lengthened LCAs are ok, cause you need about 3 degrees neg camber anyway, but if you are gonna shock the drivetrain with drag race style driving, you really should limit rear camber, so lengthening the rear LCAs ain't such a good concept at least in theory. See if JMortensen has any short shafts left that he can sell you. If not, try pm-ing Sunnyz to learn about the driveshaft shop shortened axles or contact them directly. My m2 axles have about 40 passes on them and are doing fine, but my LS2 motor is stock, not making near the power that some of the other cars on this forum are making. Best of luck with your project.
