They're the OEM all-season rubber floor mats for E92s buddy. They're sold in front and rear sets, and yes, I have both. And all 4 have 'BMW'. I mention this because they're not listed for the M3, so don't confuse them with the ones with a carpeted heel pad and no 'BMW' (which I didn't like).
These are much better than carpeted ones IMO, will always look new after cleaning them, and you don't have to worry in case you ever drive your baby in the rain
. I'd buy them from Tischer; they should be less than $100 shipped. By the way, I also bought the trunk mat in gray; it's not a perfect color match, but again, much better than the carpeted 'M3' IMO (and yes, it has 'BMW' on it as well). Hope this helps.
