I had Ron pull a rear dogbone out of his Evo 2 this weekend and I measured it. It is 2 mm longer than the dogbone I run on the back of my Evo WC. I didn't look at the upper camber link, but as was posted earlier, you just use a slightly longer ball cup to get the extra length. The rest of the rear end is the same. You just use longer dogbones, longer ball cups on the camber link and unscrew the pillow balls. Then use the zero offset rear wheels.
