Help with steering variables

Im working on a mod that allows customization to the steering and im stuck.

Code:

        ["$angle1", "range", "", "Alignment", -0.175, -0.100, -0.200, "Turn angle 1", "NOTE THIS VALUE HAS TO BE THE SAME AS TURN ANGLE 2 BUT THIS ONE IS NEGATIVE"]
        ["$angle2", "range", "", "Alignment", 0.175, 0.100, 0.200, "Turn angle 2", "NOTE THIS VALUE HAS TO BE THE SAME AS TURN ANGLE 1"]

^ Those are my variables and i want to combine the two to one the reason being that it is simple and easier to use

Code:

    "hydros": [
        ["id1:","id2:"],
        {"beamPrecompression":1.0, "beamType":"|NORMAL", "beamLongBound":1, "beamShortBound":1},
        {"beamSpring":5501000,"beamDamp":50,"beamDeform":"FLT_MAX","beamStrength":300000},
        ["fh6r","fx5l",{"factor":"$angle2","steeringWheelLock":510,"inRate":1.25,"outRate":1.25}],
        ["fh6l","fx5r",{"factor":"$angle1","steeringWheelLock":510,"inRate":1.25,"outRate":1.25}],
        {"beamPrecompression":1.0, "beamType":"|NORMAL", "beamLongBound":1, "beamShortBound":1},

Thats what the variables are going to they are editing how far the wheels turn at full lock
I need to have it where they change one value in the tuning section to a value lets say 2
When they put two it changes the value inside $angle1 to a negative ( EX : "-$angle1"
when i do

Code:

["fh6l","fx5r",{"factor":"-$angle1","steeringWheelLock":510,"inRate":1.25,"outRate":1.25}],

It does not like the code and will not load the vehicle
and when i do

Code:

["fh6l","fx5r",{"factor":-"$angle1","steeringWheelLock":510,"inRate":1.25,"outRate":1.25}],

it also does not load the vehicle.
(The difference is where the negative is placed)
If anyone has a solution that would be great.

 

Bump cuz i wanna make this work too. ive been trying to make an adjustable drift steering but im running into the same issues..

Plot twist. turns out i just found out how to do it lmao.

Code:

        ["$steer_angle_node", "range", "+m", "Wheel Alignment", 0.24, 0.2, 0.9, "Node Position", "Steering node adjustments on the x axis", {"stepDis":0.001,"subCategory":"Front"}]

         ["fh6r", "$=-$steer_angle_node", -1.09, 0.177],
         ["fh6l", "$steer_angle_node", -1.09, 0.177],

you need to add $=- in front of the one you want a negative value.
