Forza GT is a mess and my suggestion is to divide it into three categories!
To avoid a gigantic post, I’ll refrain from elaborating further why, which and where. If you still like to read my arguments, I’ll happily write it down.
TL;DR better diversity in speed and cars, more logical classification and also V8 Superstars do not belong in there!
Forza GT Group P - PI P-901-930
Rebrand “Modern Factory Racecars into Forza GT Group P”

if there are plans to add cars like: Koenigsegg CCGT, McLaren Senna GTR, Maserati MC12GT etc. those would fit here perfectly as well!
