These rotors are a good step above OEM performance. As my old ones were badly scored and already machined too thin I decided to purchase these as a replacement. After properly breaking in the carbon ceramic pads I paired with them following the very straight forward installation they performed very well. They are very smooth and very effective in hard braking. These rotors are well worth the extra money.
Very disappointed for the amount of money that was paid and the performance of the product it was beyond pitiful less than 15,000 miles the front rotors completely failed all the holes and all the slots were full of brake dust to the point where I was afraid to drive the vehicle and was forced to buy a new set of rotors and pads
