Mitsubishi 3000gt, automatic

I hit a curb yesterday on the ice and it bent my rim, but I changed all the rims and tires, but it is still messed up, when I get up to the speed of 55 it starts sounding like rocks are coming out at 65 if I hit any lil’ bump it is hard it keep control of the car, and when I turn really sharp it grinds on something but I have the right size tires on it. So what could it be????
