Very Easy

quick and easy so far

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.

Was ok
