yeah, because going from "a" to "b" was awesome, at least at the track i'm racing at. i haven't tried the "c" yet because it had always been way too much turn in for me when i was using it with my mtx-3.
oh, and i love the way the mtx-4's steering is setup to where you can change the ackerman (i.e. from "a" to "b") very easily because of the plastic inserts. it was a pain with the mtx-3 because you have to change the whole steering arm marked a, b, or c.
