I'm having trouble with the rear end washing out/hooking during initial turn-in as well. Personally I'm going to try moving the lower arm mount location to the outer hole, which should help lock the rear in more. I'm not going to change the limiters, since I think that is part of the problem...its diving too much on the front.

But, moving the ackerman to the forward hole should actually give you more turn-in (less ackerman). If you use the rearward holes, you should have a smoother steering response (more ackerman).

Here is a video which explains ackerman well: https://www.youtube.com/watch?v=5spUjQM_ykc
