So I'm actually thinking of selling my authentic JCW Challenge Front Spoiler (Lip). Normally scratches underneath, but unnoticeable up top. Delivered from Europe, took 1 month to deliver. Cost me well over $1k, but willing to sell it for $600 shipped, painted in midnight black. Originally how they came. Painted and mounted on my front bumper. No, it does NOT include my front bumper, just the lip. This is how it WILL look on your JCW front though. And how it looks mounted.
A friend assures me that the splitter can be matched to the black plastic. He used to work for MINI and said this... "On earlier R53 coopers, the aero kits were 1 piece, so the ends had to be painted to match the plastic arches." bump
