I was driving too fast on a curvy road I'd never driven and went into a 90 degree curve. It was too late to hit the brakes and I couldn't do anything but hope I could get through it. For a split second, I thought I might lose it, but the tC just held on and I made it. I put a rear sway bar on last Monday and I can say without a doubt it is the best money I've spent since I bought the car. If you drive curvy roads, you gotta get one.
