I'm in a market for a brake upgrade for my XC hardtail. Main objective with the upgrade is to shed some weight. It currently has stock BR500 brakes from Shimano.
How much weight would I loose if changing to Shimano XTR race?

Is there any better brake set options that I should take into consideration?

Does anyone know good deals currently for XTR in European online stores?

I'm light, 58kg and run 160mm rotors front and rear.

Think they come in just under 400g. You could get away with a 140 in the back if you wanted. I have 160s on my XC/trail full sus and I'm 94kg. They stop me in my tracks.

According to my weights spreadsheet, I dropped 106g from each end going from Deore brakes to M9000 XTR. I think I changed to Ti caliper bolts at the same time, so call it 100g per end on the brakes themselves. Total weight, as above, is just under 400g, and they stop very well.

My experience is that shimano brakes at all levels, deore, xt and xtr sto well. Since they don't use 2 syringes they are easiest to bleed, formula in particular can take ages to bleed for a firm level.

Unfortunately shimano are not the lightest, so also consider sram level, level ultimate, have new bleeding system so almost as quick and easy as shimano.
