Alright... I am not a brake expert.. (and those "self proclaimed ones aren't SELF proclaimed.. they ARE...)
HOWEVER.. I HAVE read.. re-read, and triple read the posts you made.. and still don't get why you are confused..
Rear brakes do near none of the work.. you admit to <30%... others say <10 or even less than that..
Your REAR rotors are 110-ish.. you say... and fronts, at least 212... okay.. so.. if the rears do near nothing.. and the fronts: most of the work.. WHY IS IT NOT NORMAL for the fronts to be MUCH hotter?..
I have an IR probe here, (my father does, actually... and I took the liberty of doing those test runs for you.
98.5 SVT
4 wheel disc (for purpose of data.. obviously svts have all disc)
Temperature of rotors before each run 62-64�ºF
Temperature: 55�º
Run 1
10mph
82.2/83.2/78.0/78.9 (FL/FR/RL/RR)
Run 2
20mph
96.0/96.6/83.1/82.8(FL/FR/RL/RR)
Run 3
50mph
218.5/221.6/111.4/112.8 (FL/FR/RL/RR)
The rotors started off at air temps, but I drove and heated them, then allowed them to cool to 62�º before beginning my run.. that was my controlled temp.
All of these runs were done at "moderate stopping rates" of an ~.5G or so. I know this isn't your <.3G perfect scenario.. but I did this JUST to see what you would have to say... All runs were cooled between with 30 minutes of non-use and ambient temperatures were returned.
Now.. as a side question.. Why does my car exhibit a slightly higher temp on one side (Right side...) when braking? I feel no pull, and it stops straight....
DISCLAIMER: This test is in no way scientific, or mistake-free.. merely an attempt at creating something more concrete than snow...
