Give it a few weeks to bed in and you will really know the difference! Try braking hard from high speed a few times to help things along 
I was bloody glad that I had the grooved discs on coming back from Devon on Tuesday afternoon. Traffic trundling along at about 70-ish, probably about 10 cars in a row when the w****r at the front spotted a police car dealing with a broken down truck and slammed his brakes on VERY HARD, the convoy of cars had a concertina effect with each car having less and less time to react. I was one car from the back and hard seem the car at the front hit the brakes so dug in hard, I managed to stop a lot quicker than a lot of the cars in front of me and steered into the left hand lane which was a stroke of luck as the girl following me disappeared into a cloud of tyre smoke and then re-appeared next to me with nothing more than a fag paper between us! Amazingly nobody hit anyone else and the c*** that caused the near pile up then just went on his way!
Note to all - power and speed is good, being able to stop on a ten p piece is better!
