I'm not doubting the majority of your post, but something doesn't seem right about the steel and CCB calipers having the same weights. The calipers are larger on the CCB system, no? I'm sure they're not made out of different materials than the standard calipers, so would posit they weigh more, similar to what I found on BMWs with CCB vs. steel.
the calipers are identical. Just shimmed out to fit the larger rotor.

Reserved for Kline Inconel OAP and rear section parts going on later this week.
In light of chronic supply shortages, I have hoarded 2 sets of new tyres.
Yokohama AD09, OEM sizes
Front 12.7kg
Rear 13.9kg
Fronts are more than 1kg heavier than the N1 Cup 2's, rears only slightly heavier (they are 11.3kg and 13.5kg)
Other useful measurements are that the Cup 2's effective tread width is about 5mm wider on both than the Yokohamas are. Could probably upsize the Yokohamas on the front to 255's very easily. I might do that for my next set if they turn out good.
Just grabbed the 2023 Nankang CR-S update for autocross while I can. The old ones will probably last a couple of more autocrosses, but I may mount these sooner to take advantage of their improvements.
Weights for just the new tires (full tread) and then with the 20" OZ Racing wheels called out by @Reedy above:
245/35R20: 26.5 lbs (12kg) - With OZ wheels: 48.5 (22kg)
305/30R20: 33 lbs (15kg). - With OZ wheels : 58.5 (26.6kg)
Not sure if this thread is still being updated, but I've got some new measurements (some are more precise versions of existing ones I posted earlier). Now using a high precision shipping scale accurate to 1/1000 of a lb. All interior stuff:
2.2 lbs - front trunk driver side pod (incl. everything inside)
2 lbs - front trunk passenger side pod (incl. everything inside)
3.6 lbs - front trunk big plastic cover above battery area
1.2 lbs - front trunk flat tire compressor (found under the black plastic piece)
1.9 lbs - rear trunk privacy cover
0.45 lbs (combined) - carbon bucket seats leather "neck pillows" on North American cars
0.8 lbs (combined) - PDK shift mechanism including paddles
Only know the last one since I upgraded to the magnetic paddle shifters from JQ Werks (FYI those weigh 0.5lbs combined with the optional metal 3RS style paddles).

I can't update the OP because RL doesn't let me edit it. Kinda annoying abut this board, even if some ppl abused it in the past. I don't want to annoy the mods with an edit request everytime we get more measurements, so plan is to make some kind of hosted spreadsheet and ask the mods to update the OP to link to it... I'll take the action to do it before the end of this year.
In the mean time, I think there's value to post up data to this thread as we get it. My GT4 mods are mostly done, so I don't have a lot of them incoming, but it's good to quantify actual vs the mfg claims, I've found the mfg claims to often be optimistic.
