The wheels can't be too thick or too thin, but if they are too thin, you will have bad traction, too thick and you can't turn, so if its possible to incorporate into your design having thicker wheels in the middle of the outside two, this will give you good average steering, and there will be plenty of traction so you won't get bullied around.... Just like you, my team has been working for the last 3 years on trying to make a design that teams can't "pick a fight" with. So far, we have had some alright success, but still haven’t achieved victory, this year we have started already brainstorming ideas, comparing and contrasting positives and negatives of all the designs, and we think we have finally found what we were looking for.... are drive train is codenamed RAM and so far, it is pretty impressive from a cad standpoint. I will be posting pictures on CD soon, (when i get them) and you will be able to judge for yourself what you think of it. We all think that its pretty cool, but the competition will be the judge of that. I just want to say, that this is some amazing CAD work, and I hope that this works out for you, just make sure that you have enough traction to handle those gear boxes, or you will regret not doing it (like we did).
We were fine traction wise with 5/8" tread, we're running 1" now so it doesn't wear out as fast; either way, it's the same amount of traction. There's no need to run thickner center wheels, and for turning we have a lowered center.

For the 4-speed we are well past traction liminted in 1st and 2nd gear, 3rd and 4th aren't but we won't be pushing in those. If we have the FPs to spare then even 3rd will be traction limited. Most likely for the season we will run AM Gen3 shifters, we just wanted something cool to play with.
