428i Gran Coupe Diffusers and Front Splitter Recomendations

GAS428 · 01-23-2015, 07:33 PM

Who makes the best quality diffusers and splitters for the 428i Gran Coupe and how much do they cost??

Can you feel the performance difference on the track or high way driving.

I can not find anything on the BMW bolt on sites

Or are they just dressing?

Purely cosmetic.

Lots of options for aftermarket parts. RW Carbon, CNAUTOFANS, etc all make them.
