WHAT OUR CUSTOMERS SAY
Absolutely transforms the look of my F30. Clip-on fit was perfect, took about 5 minutes. Quality feels way more expensive than what I paid.
Car looks completely different now. The carbon weave is clean and consistent, no cheap plasticky feel at all. Fitment on my G20 was spot on.
Arrived well packaged, finish is perfect. Stuck it on with the included tape and it's been on through motorway driving with zero movement. Looks factory.
Colour is exactly as shown, plug and play into my F20. Looks aggressive as hell at night. Everyone at the meet was asking where I got them.
My rear end looks completely different. Fitment was tight and clean. Carbon quality is proper — no fish eyes or uneven weave like cheaper alternatives I've seen.
Ordered Thursday, arrived Saturday. Went on in under 20 mins — just clips and tape. Low profile look is exactly what I wanted without going full widebody.
Subtle but effective. Gives the front end a meaner look without being too much. Stuck down perfectly with the 3M tape provided. Really happy with the quality.
Finishes off the rear end perfectly. Heat resistant, proper carbon construction, not a plastic wrap. Went on in minutes. Looks like it came with the car.
