Concave CSL et44 vs CS et47 ?

[bimmermh]

Hey there

I'm looking to buy a set over OEM CSL wheels. However since the CSL front wheels are more rare and more expensive, I wonder if there is visually a difference in the concave or not? Since the CSL is 8.5J ET44 vs the CS which is 8J ET47

It's barely visible, but there supposedly. The more aggressive width and offset are really what most ppl are after.
