Hey guys, my vs ute manual ecotec has a fair bit of power. Extractors 98 tune from chiptorque SS CAI Mace manifold spacer. mace ultra ratio roller rocker arms. And it's great in 2nd gear really puts you in your seat. However I just need help in getting the car to not twist when I kick it in the guts. I can feel the whole back end almost go, and it's not safe. Any way I can stabilise the cars rear?
