'unused parts' what does that constitute though? Tyres that weren't used, spare front and rear wings, enough spares to completely rebuild a car, the fuel left in the car at the end of the race? I'd say that nothing like that should be excluded, and I'd put money on RBR excluding them all.
At the end of the day every team in the pitlane was highly suspicious of redbull by the halfway point in the season, and they know exactly how much everything costs.
Probly wings and bodywork for that kind of cost range. Could be spares they brought along but never used as a new spec came along quicker.
But yeah still they made them and there was resources around making them.
