The wheel is pretty awesome. I managed to get one and I'll be selling it on eBay shortly. (I've decided not to do the retrofit.)
But those sills are really disappointing. I didn't see them up close until you posted the photo. I'm not quite sure what BMW is doing. They created the M Performance accessories line to sell "go fast" products to people who don't have M cars. By badging the M5 with this, they're basically diluting their own brand.
It leaves me wondering.
