On the gearing thing. I run 5.29s in the yotas under the zuk and i can run 65mph no problem with a 65 hp 1.3 and 38.5s.
And for those that think 8" yota axles are week, watch these videos, the zuk with the john deere tag is mine. Those are yotas with 5.29s and longs in the front. 38.5sx's. I think there pretty damn strong myself, and you have more ground clearance, less weight, etc with them vs a cruiser axle.
Enjoy,
