Hi Arnaud

You can sometime buy the weights or people make them out of brass sheet, and there's nothing wrong with using the stick on weights for balancing full size car wheels.

Adding weight in general will make the car less responsive and therefor easier to drive on high grip, while adding weight to the front of the car tends to make the turn in less twitchy on high grip.

At Silverstone try adding 40g of weight around the steering servo area to start with, or you can always ask me or Alec for some advice.
