Yes, Mojo hubs/stubs. I get 11.75 center to center on Mojo tires. Should match Mojo 6s stock width.. I measured about 15" on a stock K6. I could probably use a bit more width, it does traction roll periodically. Also does push turns on throttle. It's fun though. It actually hangs with my brothers TRX Sludge fairly well, K6 rtr too. The Sludge is running TRX Response Pro 5.75" mini pins, K6 on CH2'S. Which are greasy, but so are Fortress, but less so.What are your center to center wheel dimensions? Mojave stub/hubs too?
