I think went 50 to 0 in about 40 feet one time,I was speeding up to catch a green light at an intersection to turn left ,then remember I needed to go staight to run another erand first.The light was red and a car was turning across the intersection ,I loaded up those brakes as fast as my legs could pound them .No smoke ,just a high g stop .The Cop across the intersection was not impressed on my skills though ,I had that ,I now feel like a dumbass in front of everyone vibe.84 190d 2.2.
