Handling Problems!

I've been lately trying to make my Z06 an all handling car, but no matter what I do, it seems that it just wont stay on the road. I go into a turn and tap the gas and there goes the back end, or if I go into it too hard, or too fast, it understeers. I tried everything I could. I adjusted the suspention settings and everthing (maybe i'm adjusting it wrong?) I even tried taking off some of the horsepower mods so I wouldn't have as much torque and also adjusted limited slip. I put super softs and set traction back to 5 also. Can anyone help? :odd:
