And they look like there is enough room between the spokes to make cleaning doable...
I didn't find them too bad to clean when I had my CSL - certainly easier than the OEM 19s. On the other hand, they're still not the easiest, but that doesn't matter because they're an awesome wheel.
If you get new camber plates you can also run the rears on the front as well to totally eliminate any understeer than the M3 has (well, you could on the CSL anyway).
