Props to him but I got back hehe.
This is what I love about these challenges, you think you set the best time then someone shaves 0.1s off that and then you improve that time by another 0.1s and so on. Also it reminds me of the first days I got the game and leaderboards & challenges weren't working so I got into the GAF challenge thread (I'll have to dig after it) where at one point after an hour of time trials I had set the same lap time as another guy participating, I mean the exacting fucking time down to the thousands of a second.
edit:
found it! this is how we did it back in the day, oldschool style lol
Pad also but I use something that I like to call parkinson fine tune steering, I should film myself using the DS4 it's so funny. And then those hundreds of hours poured into this game start to payoff I think
