using GT5 Master Mod 1.9.1 [for GT5 2.11] RPCS3 build: "0.0.30-16146-83256cda Alpha | master"
This race was infact beginners world compact car championship (3 races), but since mastermod ignore the limits of standard game and cars partisipating, so it pick randoms cars matching your performance aka pp . from the 80 car list selected in options (favorite opponents)

The gto car was a bit dirty here on the paint since i used it just before in a 9 hour b-spec race.
The sound spikes was not present in orginal emu, maybe the action recording capture app was set too high volume on.
