Ok, I took a few measurements for you guys that are interested. The wheels/tires are 6 inches tall and 2 1/4 inches wide. That puts them fairly close to 5B fronts. I also rechecked the ride height, I set it as high as I could with minimal pressure from the droop screws (yes it has them). I got a measurement of 2 1/4in.
As you can see in this pic, the gasoline version has ALOT more going on than the much simpler direct driven electric version. The huge 4-gear plate, the fuel tank, rollcage , radio box and layshaft aren't needed.
I dont see any caster adjustments, just camber and toe are adjustable from what I can tell. If you have any pic requests let me know and I will do the best I can with my crappy camera :)
