I bought this kit along with the M sport mirror caps and the fitment is absolutely perfect. Having fitted a lot of aftermarket splitters, side skirts and diffusers in the past to other vehicles there is usually something that doesn't quite line up, clips that aren't quite in the right place but with the CT Carbon kit all my initial worries were for nothing. The rear diffuser used all the original clip locations and fixings perfectly, side skirts use self tappers but locate onto the factory skirts so hold in place while you fix them. Spoiler sat as flush as you could want on the boot lid and followed the contours perfectly, and the front splitter was much the same. Absolute bargain for the fitment & look - couldn't recommend the kit enough! Thank you!
