    Top Team Performance

    There is still 'room' to modify top team scores:

    Chimney Sweep

    A camber sweep is not uncommon. It's for "answering the question". Would not be run at zero slip angle.1311

    TIRF Wars

    Someone should check with TIRF to see if they can 'handle' this size. Because they can incline only 1 way because of spindle head real estate, the test procedure for these small tires needs to...

    N'oubliez Jamais by Joe Cocker

    Papa, why do you play
    All the same old songs
    Why do you sing
    With the melody

    Cause down on the street
    Somethings goin' on
    There's a new beat
    And a brand new song

    Yes and Yes

    Steady State: Beta-dot ~ zero. Race tires: Mu max ~ 3-4 degrees slip. Cosine / Sine inclusion should not be costing you that much extra computational overhead.
