I thought about doing the same but I held off on that idea for now. Do you want to race it or bash it ? I know it does have optional steel spur and the center diff split mounts are available in 7075 aluminum !!! rather than the regular 6061.
Just looking for the strongest basher money can buy. We usually run on a private motocross track that's pretty hard on the Arrma's. We've had as many as 6 Kratons and Talions flying through the air and have definitely found their limits. My Kraton is pretty built up and does very respectable job, but it took bracing, shocks, servo, wheels/tires, etc to get it there, but the diffs are still giving me headaches. Snapping sun gears in half, shattering pins, and shearing outdrives where the pin goes through. I could keep fighting it or just upgrade to a stronger platform.
