Without having the exact dimensions handy, the Protrac wheels you listed would suck the wheels IN compared to stock, Slash rear/4x4 pushes them out a couple mm's. The protrac wheels have positive offset meant to pull the wheels back to their stock location when running protrac arms (which are something like 10mm wider than stock) on a Traxxas slash, I'd imagine they'd probably be quite a bit too narrow for the BR. I'm still all about the Yeti SCORE SLW wheels with either a .225 or .185 hub.
Thanks. What tires have you used that do not rub with the Yeti SCORE SLW wheels?
