A Hilux is not exactly designed for drifting. If that's your only option, a sandy area or snowy location will allow you to perform drifts with ease at slow speeds.
Trying to drift a Hilux on pavement is not smart. Not saying it can't be done, but for a first timer, it's not a good idea. In a vehicle with a high center of gravity, it's easy to flip it over.
You need a rwd car like a mark x or something if you want to do stuff like that.
However, please find a closed off road or circuit. Not on public streets.
