Actually running buggy wheels is allowed since I will be running against any open wheeled 4wd vehicle from 1/10 to 1/4 scale. I will be competing against them all. I think they understand the issues of the tires not holding at speed. The problem is the foam tire cant be thicker than .300 from the rim to the outside edge (at least that what I was told) because of centrificle force. So with the gearing you stated and a 4.6 inch tire the speed goes down considerably. Tires diameter make a big difference with your gear ratio. I come up with 57mph with 4.5" tires and 25p 51s respectively.That aint going to work!!! I need to get a smaller spur or bigger pinion.

My idea is to run 2 esc's and 2 castle neu 2200 kv on 6s each, one running the front diff and one running the back diff separatly back to back in the chassis. Just an idea I dont know if it will work. I come up with 175 mph with my set up but I have no way of inputing 2 motors. Anybody have any ideas how this can be done with out breaking the bank too bad.
