sorry guys, at least from what iv'e been told and what i've read, it doesn't look like there is any ackerman adjustment on the xx4(from looking at Jimmy's review car) The only adjustment there is different holes for the steering drag link. In this case, the inside hole would provide more throw before the steering assembly would hit the Diff adjustment plates. If you run the inside hole, you will have to shorten the turnbuckles, and there may not be room for that. I think that The car is fine on the outside hole, and doesn't need any more steering.
