Tuned ML55 AMG
So far after the bed-in process, it's going pretty well definitely a quieter ride in the performance is there I'm not quite sure if the price is justified as of now however I can always make an update on this rating. I paired these with the Z 26 pads from power stop as well if you're doing front rotors on your ML 55 AMG I'd recommend this. 
Bottom Line Yes, I would recommend to a friend
