1) Remove some multi-flex screws
2) Ackermann to the forward position
3) Back to the 9* caster blocks from the 12*
4) Layed down the front shocks all the way (inner hole tower, outer hole arms).

I often overlook the multi-flex stuff, but it made a huge change in the way the car handled and really toned down the twitchiness of the car. However, it did not affect the low speed steering of the car in a layout with a bunch of 180s, the car was very stable but didn't push at all.

I'm not convinced about the 12* blocks on clay, the steering coming out is noticeable, but can be too much sometimes (layout has a lot of 180's, so you would think it would be beneficial). I'll keep them around in case I run some carpet.

I would like to try thicker fluid in the front and rear diffs too, just didn't have enough time. Changing diff fluids is a PITA though to do on race day, I really wanted to focus on things that can be easily changed between heats.
