ACR driver is very conservtive...brakes late and is off line through many turns-thus scrubs speed and gets on throttle late coming out many turns because not set up. Drives smooth but you can see a better line by the car ahead.A little more seat time and he will be flying around the Q1. Not taking anythng away from the Q1 driver or car-they re fast. But I have driven both and the ACR is faster on a track.
