As teased earlier in the thread, i just added a new section on K' FH4: Car Masteries and Perks.
The logic here is that we select a perk, then we have a list of all known Perks Grids grouped by the given perk rank, then we can list all known cars having that grid(s):

The K' database currently includes 77.2% of all car masteries grids. That's basically my garage, but the more i advance, the more difficult it is to complete the grids. If someone want to contribute, sharing a pic of the screen of any missing car Mastery grid by any way (but not in this thread), it would be welcome (by all, i guess).
Also,
1. In the main car list, cars with a known car mastery have a triangle after their name.
2. On a car page with a known car mastery, there's a button to see other cars with the exact same grid.
