Once my 340 gets here I'm looking to modify a few things but I'm not sure exactly how/where to look. First of all I'll most like swap the kidney grills to black but everywhere I've looked only shows they offer f30 grills for 12-15' models and nothing for the 16 yet. Also, I'd love to change the front splitter to black as well as the rear diffuser but I have the same issue. Nothing offered for 16's yet. Id also like to swap the chrome muffler tips for black but I can't seem to find those anywhere. Anybody have suggestions or tips where to find this stuff other than through bmw directly? Thanks.
