Deposit behind rear wheels. Way less ice than the front. Any explanation for why the front had more snow build up behind the wheels?

The rear is operating in a relatively cleaner track, the local area body might be a couple degrees warmer?

And the front wheels would have compacted the snow and ice as well as plowed away what might have otherwise come in contact with the rear wheels.

Depends on the length of the vehicle: fineness ratio.

We'd need specificity in order to even begin working towards an answer.
You've been provided with enough tools to work it out on your own over the past year and a half.
The tail is the most difficult modification to master. And the granularity of necessary data required to pull one off successfully, cannot be over-emphasized.

That was my impression. Even just filling in some of the area behind the car that would otherwise have negative pressure.
