i have a stampede vxl 4x4. I have 50k fluid in both diff and trencher for tires. I know i need to switch the rear diff to 30k and get sway bars. I use a 2s lipo and I have steering issues. I either under steer cause the front tires get picked up or over steer and just flip over. I can't take under turns under power i have to release the throttle and take a turn wide. Will a center differential stop my front wheels from coming up and allow me to take turns on the inside and have power coming out of them? I run the tracks at UNOH school. So i do mostly short course i do bash a little bit but nothing extreme besides jumps and occasionally climbing something.
