I selected these as I fitted their matching Brembo discs to the front of my AMG Line C300h Mercedes. I was undertaking a complete pre-MoT brake survey, and replacement noting that the rear calipers are manufactured by ATE. I suspect that Mintex manufacture the discs and brake pade for Mercedes under licence but with fitting a matched set of Brembo discs on both the front and rear axles, plus Brembo pads i could see they were matched for use on the same axle. The discs came packed as a pair, with a locking screw already prepared with thread locking compound. In my set there was only one replacement screw, however the ones removed from the car were perfect after a quick clean with a wire wheel. The Brembo discs were checked for tolerance and specifications before fitting and found to be perfect and were a snug fit onto the rear hubs. I am confident with Brembo brake products having used them extensively over many years across a range of performance cars and motorbikes. I am delighted with the selection and purchase. Highly recommended and they are quality products very sensibly priced.
