I'm not for sure, never having a 6 series. On May 25th I posted these springs and got the same question. Rob Anderson says they will. You might try and email this Rob Anderson (see post on May 25th) and see if he has first hand knowledge of this. You may want to try them. If they don't fit, you can send them back and I'll send your money back. The only thing you're out is the shipping to send them back. Thanks, Eric grieb
