I decided to not use the old top mounts and to order new ones from the factory. Main reason was that it would cost me almost the same to remove the old ones and install them to the new coilovers (work labor is very expensive here!). As an additional benefit, the new top mounts have different part numbers and they are stiffer (harder rubber?). They pair better with the stiffer coil springs and can be approved by TÜV. I think that camber plates cannot be approved.
The rear top mounts were used in the BRZ tS model and the front ones I was informed that are used now in the revised BRZ model. Probably, because the new stock front springs are also stiffer.
