Cheap product, Not what I paid for, one was defective, but I could not return because it was thrown away by the shop since I didn't open it at home and took it the shop. Made in China, probably made the cheapest way, the sides were not grinded smooth like the rotors should be. Not happy with the product. Next time I will go to the store and buy it.
