Try upgrading your car and hit the top speed 3 times by braking when you reach the speed record, accelerating again, braking again until you hit the speed record at least 3 times.

Or you can go for Tilt B and let go of the gas once you hit 170 mph, floor it once more until you hit 170 mph again, let go of the gas again, floor it once again until you hit the third 170 mph needed. But make sure it's safe to do so since you might risk going off track if you wanted the speed to count.
