I'm using Modern Motorsports 4 bolt cv adapters with a 3:70 zxt differential in my 78 280 track car. The inner cv cage has been reversed to shorten the axles per MMS instructions. My car is very low. The front rocker panel is at 5" and the rear at 5.5". I'm running 2.5 degrees negative camber with 1/8" toe in on the rear and 16" 265-45 tires. During very hard cornering and subsequent suspension compression, I'm destroying inner cv joints. I have gone through five axles to date. My new axle man has informed me that effective cv travel has been limited by reversing the inner cage. and in-there the problem lies. But, the axles are too long and will not fit without reversing them. Also, I have Ross's adjustable rear control arms and they are adjusted out about as far as they can be moved safely. Has anyone else had this problem? My axle man has suggested having shorter axle shafts made. Can anyone recommend someone who can make custom axle? Is there another solution to my dilemma? Your thoughts would be greatly appreciated.
