The E46 M3 has somewhat limited front wheel & tire fitment.
Some of the aggressive front wheel fitments for street cars are 9.5J+28ET with -2.0 camber on a 275.
A slightly widened fender can unlock new optimization 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.
I documented the EU to NA logistics, unboxing impressions, preliminary DIY fitment, new wheel & tire fitment possibilites along with the required hardware.

Professional installation is required.
From my experience with it, the carbon fenders requires little to no fitment work. It does require a complete paint & finishing process, along with installation.
No hardware is required to mount the new fenders. The OEM fenders' mounting hardware is re-used along with the side grills and turn signal lights & trims.
