    Since the Ibishu Pessima has rear-steer, I thought it'd be funny to pull a Westen Champlin and do a race in reverse. However, I can't plug in inverted gear values without breaking the game...

    Try this example; you have to add a negative (-) under the transaxle.jbeam's gearRatios gear definition. I added these values and added gear ratios to the variable gear names.

    "$=-$gearR3"
    "$=-$gearR2"
    It might also be proper syntax for this, so try both.
    "-$gearR3"
    "-$gearR2"

    GOOD LUCK!

    "variables": [
    ["name", "type", "unit", "category", "default", "min", "max", "title", "description"],
    ["$gear_R3", "range", ":1", "Transmission", 1.00, 0.5, 5, "Reverse Gear Ratio 3", "Torque multiplication ratio", {"stepDis":0.01}],
    ["$gear_R2", "range", ":1", "Transmission", 1.55, 0.5, 5, "Reverse Gear Ratio 2", "Torque multiplication ratio", {"stepDis":0.01}],
    ["$gear_R", "range", ":1", "Transmission", 2.95, 0.5, 5, "Reverse Gear Ratio", "Torque multiplication ratio", {"stepDis":0.01}],
    ["$gear_1", "range", ":1", "Transmission", 3.05, 0.5, 5, "1st Gear Ratio", "Torque multiplication ratio", {"stepDis":0.01}],
    ["$gear_2", "range", ":1", "Transmission", 2.25, 0.5, 5, "2nd Gear Ratio", "Torque multiplication ratio", {"stepDis":0.01}],
    ["$gear_3", "range", ":1", "Transmission", 1.76, 0.5, 5, "3rd Gear Ratio", "Torque multiplication ratio", {"stepDis":0.01}],

    Yeah... I tried to do that. It didn't work. It just completely disables the transmission. I'm not sure why.
