On our return trip from Tail of the Dragon this weekend, we did about a 13-hour driving day (from north GA to Omaha), and I measured a peak trunk temp of 106F with the factory air deflectors installed (using an outdoor thermometer with min/max memory). Unfortunately, I don't have a good pre-deflector temp, but as a reference point, the frunk max temp on my Z06 after a similar full day drive (~7-8 hours) with the license plate filler removed for full airflow was 118F. IMO, they do seem to reduce trunk temps as our luggage didn't seem to be as warm as any of our previous C8s after a long day of driving.
