Bmw M5 F10 brake disc skimming Scotland

[650i]

Hi guys. As the title says I am Looking to get my front discs skimmed. As they are 400mm I am struggling to find someone that can accommodate such a task. Highest I’ve seen was 393mm in West Lothian. Or a place down in Leeds can do it but I live in the Falkirk area. Anyone know of a garage that’s within 1 hours drive or so?

Thanks guys. I’ve been in touch with them and hopefully going to get it sorted. Long trip ahead!
