Seems like they would have to be better…but I wonder if the main source of stopping power is limited by the tires.
Logic:
The factory brakes can put enough squeeze on the rotors to cause the ABS to kick in.
If that is the case, then time to stop is really limited by how much friction you can maintain with the tire on the road?
Likely the perf upgrade provides better heat dissipation and can stand up to more brake usage in less time (ie, better fade resistance?)
Not trying to start an argument here…just wondering what the upgrade brings in performance. I may consider doing it…but my reality here in the great plains is a lot of miles with the cruise on and no stopping. My biggest brake load situation is towing, and my trailer has very capable brakes.
