I was going to say "Just the usual extra info", but this is of course Ferrari, so nothing can be called 'usual'  So here is some special supplementary data for this iconic brand series...
There are 51 events (48 Trophy + 3 TT) and the rewards 25-50-75-100% are split 9-15-20-31GC.  You will need all three cars for 100% and only the FXX-K EVO can be upgraded enough for the final three cup races.
75% can be reached without the EVO if you have the Superfast, and the LaFerrari upgraded to around PR85.5:

Both my cars are fully upgraded, but I think that means you can reach 75% without LaFerrari's four most expensive GC upgrades...
Having earned your EVO in the LTS you'll need to spend a mere 630GC more to get to 100% here!!
