Here’s a copy/paste from an older post describing my experience with the 4 pot track pack Brembos vs the S550 6 pot. This comparison is made running G-Loc R16’s in both setups. I’ve learned that R18’s are the magic sauce for the S550 setup.Seeing that now. After reading through the relevant threads, it’s starting to come into focus.
For me braking feel and performance are not necessarily the same. Performance lap over lap is critical, but feel builds confidence, confidence builds speed.
like probably most here I prefer a pedal that almost stops dead and braking power can be manipulated by pedal force rather than pedal travel. If I can’t have that I would take a pedal that increases braking force with travel. Last on the list is significant dead pedal travel, then full braking.
Bottom line, I am concerned about pairing the s550 pp brembos with the s197 master.
like everything else, ROI becomes a dominant factor. My initial thought when starting this thread was the referenced kit seemed like more brakes for less money than the track pack brakes. maybe not the case.
Initial bite is consistent despite the change in caliper/pad size. With the larger calipers, I can apply more force which is where they stop more aggressively than the smaller caliper. I find it much easier to modulate the S550 setup as well - less of an on/off switch, making the pedal stroke much more linear through the range. Some have noted they feel the stroke is longer with the PP calipers - I’m not sure if it’s that, or if it’s just more linear. Regardless, trail braking is greatly improved with the S550 setup.
