Audi Sport Quattro feels too weak and understeery, which makes this car unbalanced, I suggest changing it to more powerful Quattro S1 to make it more competitive comparing to Peugeot 205 and Lancia Delta S4. Also you need to match sound with revs, cuz now they don't actually match, for example on 6,5k rpm you hear the sound like it's rotating on almost 9k rpm. It should be much lower.
