Honestly as with any narrow track it's always tough to overtake but I find that track knowledge comes into play massively with that, as you've sort of got to plan an overtake on a section where you know you can get a superior drive off the corner and overtake straight after.
IMO a good part is early in the track after the initial first tight section, there's a longish straight followed by two relatively open long right hand corners IIRC... most people hit the brakes hard there because I think it's uphil and slightly blind, but you can definitely full throttle over that in certain cars and catch them on the inside.
There are plenty of spots around the track but with it being so narrow you've kind of gotta get your elbows out a bit , which most people online have absolutely no issue with doing lol...
