the item Brembo 09.B754.21 was not clear in the information about the quantity of rotors the actual picture and other informations about fitting. If I was looking for my car directly from your website I would never arrive to this item. My research was direct from Brembo Italy, where I looked for my car, but strangely the box with this part number show 2 rotors inside and I get also answer from other vendors that confirmed that the rotors are 2 inside the box, so I called in your shop and a rappresentative confirmed that the box has 2 rotors inside, when I received my order the box show 1 rotors inside also in the description printed in it, it's not really a problem, my goal was to have my work done, but really was confusing informations and a big lack in description on the item.
