experience with distance discs in winter

Hello, yesterday I also built the winter tires on it. wanted to take off my distance discs from H&R first, but then I let it be and left it to it. (how cruel it looks without the parts) how is it now in winter when salt etc get there, can I beat them at some point only with hammer and chisel from the brake disc down??? who has experiences with distance in winter and can give it up here. thx and greetings
