Hi Guys,
Some of you may have already bought front and side diffusors from S Factor already but he now makes a rear diffusor for our car. Take a look at these pics. It is pure quality. I really want one but he doesn't have an M3 rep rear to test fit on. For any E90 and E92 guys looking for a great rear diffusor you should check him out.
His instagram is s_factor_fabrication.
Anyone have an m3 rep bumper they want fitted with a diffusor? He needs a local person for test fit.
