M3 undertray
Yes it may sound a little crazy but hear me out. Is it possible to run the m3 under tray? I looked at the bumpers of both m and non-m cars and the bolts should line up. This will then inter allow me to use the skid plate from the m3 as well. So when everything is said and done more air will flow through the rad (while driving) and the front end will be stiffened. I don't want to pull the trigger to early so let me know your thoughts and or ideas.

It's been done, doesn't bolt straight up. Think someone had to drill and add rivnuts somewhere (subframe?) but I forget. Consult Google.

Yeah the fitting of the m3 subframe frame brace but as well as this. [IMG]https://c1552172.ssl.cf0.rackcdn.com/552400_x800.webp[/IMG]
Probably have to find a company to make on or make one myself. I am trying to get more air flowing through the radiator while driving. |

I have done some research to see if this idea realistic. This is with the Porsche smile vent for an idea. I don't have a good measurement but I am guessing I need to put the vent 3.5 inches from the front of the belly pan. The last photo is another option for the vent. A posible problem could be the depth of the vent but I don't have a good understanding with aerodynamics and cooling.
