Well, the slash 4x4 was out of the race from the start.
As for the beadlocks:

One picture note says "Screw on Bead Lock Rims with All Terrain Tires hook up the All Wheel Drive System" another note says "Bead Lock looking rims and aggressive all terrain tires."
I should just get the 10SC because jammin is so unclear on the facts
