I would argue that, honestly. Yes the 60 series, when maintained well DOES work decent, but I would put the system I'm running now against a good condition stock configuration any day and bet I would stop much quicker. Likewise, I would bet a same weight 60 series with FF 80 rear and Tundra (or 100 if it could be done) fronts would stop in even less distance than my own. Yes there are effective brake setups, but they can always be improved. Thing is you have to have the right balance between front and rear, and the appropriate mechanical advantage that the proper sized MC would give you.
