I'm not aware of any for rfactor or GTR2. Roosevelt was in the old "Spirit of Speed" game, and has been made for GPL. Perhaps some kind soul could convert the latter.
Brooklands37 is a good track for these cars, as are any of the old open road circuits (Reims, Solitude, Brno65, etc.; and there is Nurburg_67-70 which includes the Gesamtstrecke - the combined Nordschleife and Sudschleife - only used for a handful of races in the late 1920's).
