But right now I think all of the change you get in flight is from the weight of the wheels.
If you felt absolutely no rotational change in the chassis with the tires off (assuming this is strictly a rotating mass problem), that tells me that the forward rotation of the diffs, belt, and spur gear assembly are offset by the reverse rotation of the motor and idler gears. Inertia, change in rpm, and orientation of rotation determine how much any given item will contribute to the overall "net rotation", so with heavy diffs and spur gear spinning relatively slow compared to the lighter rotor spinning 5-10 times faster seems like an accurate assessment that the mass of the tires is 95% accountable for pitching the car mid-air. With an 8th scale buggy or the scte the motor and center diff are only fighting for left/right rotation of the car while the front and rear diffs and tires have nothing fighting against them for fore/aft rotation.

That track is quite a bit bigger than TRCR ....
It's a good thing NASCAR teams don't take your advice and use the setup they develop and win with at the Daytona 500 for the rest of the season on every other track. They would lose sponsors so fast after losing (or not even qualifying for) spectacularly at every other track until they come back to Daytona later in the season it wouldn't even be funny.
