Here is a shot of some of the "black stuff" that is still falling out of the tires every time I touch them. Turning the tire inside-out, you can see that there is still plenty of whatever it is left. This stuff was all over the aluminum hubs, and was not smooth- there were clumps and it did not sand off evenly. If this hadn't been from a car that was just released last week and purchased from a trusted dealer, I'd think it was a used car.

But hey, after a couple axle spacers and some set screws in place of the axle risers on the front , plus a swap to Paul Gage tires along with the removal of the magnet, this car runs as good as it looks. It just took some extra effort that I'm not used to putting in to a Slot.it to get it there.
