I've only had 2 rides on a night track but they did their job and I didn't notice any fading (2014 SRT8 Challenger). I'm curious to see how many sessions I get with these pads as they seem to have taken some abuse in the two 20 minute sessions I had. Despite my smooth rotors I have noticed some wear on all 4 pads but I push the car to its limits under braking. Based on my first impression I would buy them again.
