Sorry for the late response haven’t been on much. My base came with the red painted calipers so I ordered the PMU club racer pads for the premiums and have had no issues so far. Didn’t have any install issues either. 1 year, ~9k miles and 14 HPDE days. I’ll try to measure the rotor when I can...
I have a 2023 base manual, the calipers are red and same as the premium models. I’ve had a good experience so far with the Project Mu Club Racer pads and Endless RF650.
