About that but you have to post your own one to Royal in the UK which is about another €25. I had problems with a couple of wheels I got done by Royal so ended up wasting time and money posting them back to the UK to get sorted. Ultimately I stopped using Royal due to the problems I had.
There’s another guy on m3cutters called Lovett who can get the retrimmed too. He uses a company called Twiggy Design in London iirc. They did my e46 wheel and it’s great (after their second attempt!)
