There was/is some debate regarding whether this trophy relates to Club Drift Points or individual Drift Points.
I can confirm that this is individual Drift Points and doesn't relate to your club in any way.
The best way to boost drift points that I found is:
Single Race > Time Trial > India > Tamil Nadu 1. And I liked to use the Ferrari.
I was level 36 when I started and I only had to do a few boosting sessions of 100,000 points each time. This is also a useful way to rank up quickly if you're going for the Level 50 trophy.
You can check your Drift Points via:
Statistics > Overdrives > Drift.
