Putting that power to good use - Forza Horizon 3: Hot Wheels Expansion Pack

Score over 50,000 Drift Points in the Hot Wheels Twin Mill in Horizon Hot Wheels - 10

You need to do this in a Drift Zone, using the Twin Mill.

You don't need to upgrade the vehicle at all as it already as a massive amount of horsepower. I recommend you do this in The Sidewinder Drift Zone. You can either Drift or E-Drift, it's your choice.
