I have 40,500 miles on my original BMW rear pads on my GS8 and was looking for information on replacement options. I saw Cowboy2 comment and gave it a go. Worked great. About 10 minutes total. Since the original pads worked well for my type of use I have replaced them with factory OEM. However, these do not have the wear indicator grooves that were on the original pads. Anyway thanks to Cowbow2 for his advice.
