If you are able to open the 2017 Season (Endurance GT Racing) or Porsche Performance Showdown you can look at the PORSCHE 911 RSR (2017), even though you can't select it.

This will tell you the Performance Stats, the PR, and the total # of upgrades you have placed on the car. From there, you can kind of work out what your prior upgrades were.
