The M3's grip very well when the track is packed in, but there really only work good if there is a little moisture in the dirt. Once the track starts drying out bad and "grooving", the M3's roll over pretty bad. If you're running on a track like this with the M3's, I'd suggest running a 2.0-2.5 rear block to loosen the rear end up some. I've found that the M2's are dialed in most places- the M3 is kind of iffy on some tracks.
The new Ackermann plate is CNC'd (I believe) and a bit thicker, removing flex and keeping the ackermann straight. It also may have less bump steer, I don't know. I don't drive my car hard enough to bend the ackermann. One fix I have found is to run Kyosho rubber sealed (flangeless) bearings and a shim with a larger O.D. than the bearing instead of the stock flanged bearings. That way, if the ackermann does flex some, the flange doesn't break. Just a thought.
