I got a 143.4xx on the tuned car with a DS3. With a bit of practice I could do better as I can beat my ghost through the 1st half then fall behind, or fall behind and then beat it in the last half.
I also did a lot better once I moved Gas/Break off the stupid face buttons so I could control them properly rather than spinning the wheels out all the time. The right joystick really doesn't work for me as my thumb slips off over time.
