the caps are made with fake carbon fiber and cheep metal would not want anyone else to make the same mistake i did by buying them!!
The metalfinish and machining was excellent. The stck-on "caron fiber"/lables are poor. The "carbon fiber" looks nothing like actual carbon fiber. The lable printing is cheap looking with sloppy edges. The stickon pad seem very teporary. The one for the coolant tank would not even contact te surface of the OEM cap. The worst piece was the washer reservoir cap. The astc ring inside the metal cap is supposedto rip the lip of the filler tube. It will not expland to do so. I tried both rings included. It is going back for a refund. The stick on "carbonfiber"/lables are not going on my car, I'll use e caps I kept as plain billet. Not a $200 set.
