A slightly widened fender unlocks new possibilities for front wheel fitment.
This is what the CSL should have been fitted with - 20 years later, here's a German take on an OE+ design.
In this Special Series, I document the EU to NA logistics, unboxing impressions, test fits along with my recommendations on new wheel & tire fitments.

The added 10mm enables entirely new wheel & tire fitments. I tested a variety of fitments and put together an extended tabled with my recommendations.

Professional installation is recommended. You'll need a body shop to paint them, and potentially adjust the side trim fitment.
Been there, done that.
