Interesting, any more shots? Worthwhile a separate thread on these to not go OT for the OP?
OP - as Gaz said, not only do they prevent fade on many hard stops - but we are talking about a larger pad face, larger disc, those in themselves will dissipate energy more than the j-specs - it's not just the contact patch : grip that gives the point where ABS would hit - it's energy dissipation.
Also yes, we all try to accelerate at a sensible moment - but you're not counting for other people's stupidity.
Suddenly on a stretch of road where you used to hit 70, you're now hitting 100-120 for instance, the energy required to brake at higher speeds is higher (not sure if it's quite logarithmic) but more power = quicker gain in kinetic energy. In a single I WOT far less than I did in an NA that's fer sure!
As for rad/oil pump - I'd just be looking at their service intervals - if you're doing an overhaul for a single - wouldn't it be prudent to have best OEM components where they are OEM wherever possible? I guess that's just my philosophy.
