As stated in my maximum attack achievement guide, you can get this easily.
Start a custom rally with kenya as the location. make sure that the damage level is set to severe. Choose lake nakuru as the stage for the rally and choose the fujin for your car, located under group a. After turn 3, you'll enter a somewhat straight part of the course with a slight curve. you'll need to reach over 150 km/h and then crash into a rock on the side of the road or at the house next to the next turn. you'll know when you did it correctly when the race immediately ends for you and the achievement pops.
