We might all be overthinking this? Our team used the kit chassis, long configuration, with 6" wheels that are just like the 4" kit wheels. We notched the ends of the chassis for wheel clearance, so we could use the normal length belts. We competed in two regionals, and were semifinalists in one, and finalists in the other. No issues with driving. The rocking is a feature, not a problem, it allows the robot to turn easily on carpet. The 6" wheels let us go over the scoring platforms ok.
