If you need to make this mini-Fiat a serious car - use this update. Install is the same so no need to repeat everything for the update, just overwrite the previous in "..\content\cars\".
Important: in "ks_abarth_595ss_s2_turbo" - "sfx" rename the sound bank to "ks_abarth_595ss_s2_turbo.bank" or the car refuses to load. Another fix is "replacing" the sound in Content Manager with the same from the original Abarth 595 S2.
