During lap 1, your goal is to cleanly gain the lead and set yourself up for a good lap. You'll be going for the achievement during laps 2, 3 and 4. If you don't have the achievement by the beginning of lap 5, it is advised that you restart the event as AI cars will get in the way during this lap.

The goal is to get a lap time of 59.99 or lower, in this stock car. There are various ways of approaching this, but keeping to the racing line and controlling your drifts is essential. The best line through corners is to approach from the outside wall, steer into the inside apex of the turn, and then keep speed through the corners to the opposite side wall again. This line will allow you to maintain the best speed through corners and minimize unnecessary drifting. You will need to drift, but the goal is too not drift too much. Drift to slow yourself down, and to get yourself through the corner, but straighten out as soon as you have enough track to do so. The most important turn of the entire track is the large downhill hairpin before the long straight. Make sure to get maximum speed through this corner and come out of it with a high top speed to shave off a good amount of seconds.

Also, keep in mind that you have unlimited flashbacks. If you are having a really good lap, feel free to spam those flashbacks and make sure you get every corner perfect.
