I will add this...
Our very first trip after having the disc's installed, we were traveling down a local 2 lane.
At the last minute, I had an elder lady pull out directly in front of me from the retirement home, she panicked and stopped 3/4 of the way in the lane.
All I could do was stand on the brakes and hope I get slowed down enough for minor impact.
I stopped completely before reaching her.. Afterwards, I looked at my wife and all she did was smile and say "thank god" we had them installed...
It was a good feeling, it felt like I was being yanked backwards !
