There is no way of removing it if I need to either now.
I would be VERY suspicious of any rack that is riveted (or nutserted) onto the roof - unless all those fixings went into the supporting structure of the roof and not just into the jam tin thin roof material. There is just too little support for sideways forces and the pressures placed on them by off-road use. Rack loading needs to be very carefully considered, I think.

I'll be going there this Arvo and confirming they have reinforced the riveted section

So I went in to the tradesman roof racks shop in Bayswater this Arvo.
Regarding the rivets I asked him, and he assured me the mounts are drilled into the roof, in locations where the side panels overlap the roof panel and also the roof reinforcing crossmembers, so there is sufficient steel there to take the weight and wind load. I feel confident in his answer so I guess for me all good.
The only way really to be sure would be to peel back the roof lining and take a look but I'm not willing to do that.

Remove the rivets and nutsert the fecker. Rivets will eventually fatigue and break.

FWIW: Unsure, but please do consider there may not be enough depth in the cavity to insert a riv/nutsert and possibly why they’ve opted for a stubby/shorter expansion rivot instead Old Mate?

Ahh yes old chap!* as I'm puffing on a pipe* But I would nutsert with a wide "mudguard" washer on the inside to assist. Its all about the footprint for grip....

Unsure of the roof cavity config, only meant Old Mate’s that from my experience elsewhere that trying to install say an M8/10 rivnut into a say 20x20mm SHS doesn’t work as rivnuts that I have on hand are too long and bottom out on the backing material before their grip designed half is in deep enough ready to compress if that makes sense?

He's saying the stiff prong may be too long for the cavity pre-wrinkle.
