Wanted to give you all an update on the "dead" zone with the s550 upgrade. Installed gloc R18 pads last week and then ran Road America over the weekend. Wow what a difference. 80% of that pedal movement was gone and the stopping power is next level. If you are tracking your s550 setup. Gloc R18.. a must. O and of course order them from @OPMustang Tim. Next update will be adding gyrodisk. Tim said that will even make the pedal feel better as well.
