I prefer the gloss black too, I’ve fitted the tcr skirts, rear valance and front splitter, also had the mirrors done gloss black. The rear valance was only a pattern one from eBay but doesn’t look any different than the genuine one. The side skirts were a bit more involved to fit as the support rail underneath them is in a slightly different place than on the original skirts so couldn’t use the existing mounting holes for that. The skirts themselves are double sided tape along the top edge and underneath they fit into existing mounting holes in the body
