I was running with some of my friends last night and they all have mp9's. If I was behind them on the straight I was able to cut inside them going into the sweeper with some much speed. It was awesome. If I could just get rid of the car stepping out, that would be great. It does it with the slightest throttle input.
I would first think diff shims but since you changed those I would make sure there is no bind in the arms. that will make it loose getting on the gas and inconsistant. if the chassis and all is well and you need more on power traction you can drop the center diff to 4K and run 5F 4C 4R. that will make it a little lazy getting on power.
also increase front droop if the rear is getting loose, this will dump more weight on the rear tires
