Yes, the front Cvd's for both cars are the same and interchangeable. On my MTX3 I always ran the rear CVD's on all four corners. When I got my MTX4 I was told that you needed a longer CVD on the front and got the front CVD's for my new sedan. At that time all I had was 2mm offset wheels and when I set my front track width to 199mm I found that the CVD's were binding inside the outdrives. I use the MTX3 rear CVD's on the front of my MTX4. Even when I use 1mm wheels, I still have no problem with the MTX3 rear CVD's being too short. My hope/guess would be that when I go to a smaller offset than 2mm, the MTX4 front CVD's will not bind on the front of my car. As long as the CVD doesn't pop out I would prefer to use shorter CVD's so I can make my car as narrow in the front as I would like to.
