Just got back from a track day and thought I’d offer some feedback on this setup. I ran Thunderhill 5 mile configuration today, which is not particularly taxing on the brakes, nor am I a particularly fast driver, but nonetheless I felt it was a good test of them. With RS3 ducts, Ferodo DS2500s, and Motul RB660, everything functioned flawlessly. Didn’t have any fade, pedal travel was solid and linear all day, it was easy to modulate pressure/weight shift, all in all went very smoothly. I am sure a faster driver could probably push them over the limit, but if you’re lazy like me and don’t want to be swapping pads at the track, this a great one and done package.
I am hopefully running Laguna Seca in a few weeks, which should be a tougher test, so I’ll try to provide an update after that as well.
