The f20 splitters do not fit...
It`s not possible to line them up properly.
When you adjust one side correctly, the other side disappears under the bumper.
the radius and the shape of the splitter is completely off.
So I had to order the oem bmwp carbon ones which Harlequin was speaking off.
Plus I ordered the bmwp carbon interior trim and the smaller prefacelift mirrors.
damn that was an expensive day!
