To the Top Achievement
To the Top100
Achieve a 5500 Rep Rating.You will get Rep for leading laps, completing races, racing clean, racing with the hardest difficulty and with all the assists turned off, and by completing sponsor and team contracts. This will come natural if you go for the Complete all the Sprint Driver Challenges and by going through the Career Mode. I haven't even finished the Craftsman Truck Circuit and I already have 2200 Rep. So it won't be hard to get these 3 achievements.
