I don't think its cheating - or an exploit really.
I never thought that about the Sloppy Spring setup either. I would have preferred that it not work, but it did and therefore, I used it.
The idea of the driveway mechanic just adding a single ARB to the rear is not uncommon. So turning down the front wouldn't seem out of line. I wonder at the 40 (max) setting for the rear, and probably question it. I will test out more sane approaches later.
Also, a part of the Blooze Toon is setting the ARBs to the inverse of the Weight Bias just as the game does. Therefore, this little development will have to be examined from that aspect as well.
