Anyone know where I can get Mirror wind diffuser for the E63? I know there are tons in the market for porsches but I am having a hard time finding anything for amg.

 

Anyone? If I can get my hands on one for an amg gtr one I can work with that.

 

Try experimenting with a pice of ABS plastic a heat gun and some double stick tape.
I did a deflector for my 991 Turbo S to cut out the helicopter wind noise when the driver's window was down. It worked like a dream and was able to get it small enough so that it wasn't ugly..
