I actually bought a set of these and tried to adapt them over a year ago. They're not even close.
Mitsubishi has a similar kit, only smaller guides for the Evo. Mine had them on it back in '03. Not sure how effective they were though.
On my 135 I had purchased some F30 backing plates and installed them due to the bigger scoops. The M3 is very similar though. The factory ducts can be bent/pulled inwards to help out somewhat, but the brakes still need more direct air
