Hope someone can give me some advice that makes me feel more at ease. I did a track day and I am an experienced driver. After 15 minutes on a 2.9 mile closed road track front rotors were 500 degrees and rears were 750. Front rotor temp doesn't bother me but I am concerned about the rears. At no time did I experience any brake fade and there was no pad deposit on rear rotors. Does anyone know what maximum temp rating is for rear stock pads on a 2013 SL550. I am hoping MB over engineered the brakes so I can forget about it and just have fun.

Thanks to anyone who responds.
