George, if the wheels are 40 series dish, they will mount up .60" wider per side on my Revo, making it 1.2" wider overall. Does anyone know if this is asking for trouble with bearings? I presume handling will be different due to track width increase.

I would be interested in the racing style wheels and tires if I'm not going to screw up the truck. I will have to get 23mm adapters also.
