    Optimal cross weights?

    What is considered "good enough" cross weights (for my AI car...) .

    Yesterday, we corner-weighted my car without ballast and "as raced" and got a 48.6/51.4 cross weight (LF/RR vs RF/LR) and a F/R distribution of 59/41. L/R distribution was 52/48.

    LF: 840
    RF: 824
    LR: 617
    RR: 522

    Total: 2803

    I know that the ballast I add (pretty much max weight of 150lbs will be needed) will help the F/R distribution and L/R distribution. The ballast will go in the passenger floorboard, forward of the rear seat bulkhead.

    Ideas knowing all our tracks (for the most part) are CCW with lots of Left hand corners?

    tracks that have all the "important" corners going the same way it might pay to wedge/de-wedge the car appropriately (as well has have an asymmetrical alignment, etc)

    Crown Royal in one hand and Coca-Cola in the other - then mixed in proper ratios to form a perfect balance. 8)
