No drilling or cutting required. It just bolts up. I did it on jackstands. I used a Dewalt cordless impact gun. I would highly recommend using an impact gun whether it be cordless or air. You will never loosen control arm bolts without one. It is quite easy. It took me about a half hour to install including jacking up vehicle & jackstands. You will love it. It changes the way the car handles though I did do the rear torsion bar & the upper strut bar also. I don't know if it's intent was but I do notice since I installed all 3 they eliminated a lot of my torque steer. They are simple to install. Remember use an impact gun for the control arm bolts for the 6 point brace. You won't regret installing. Good luck !
