Been doing lots of research on spacers.. found that 18/15 looks the most aggressive on the E92 but wondered if you could go 20/18. Recently I found a thread with someone running 20/15 and now I'm thinking if 20/18 is the ideal setup. Here is some links so you can be the judge. I want to be ABSOLUTELY flush with the fenders without rubbing obviously. Will be lowered on RD sport.
20/15
