The most successful Abarth 1000TC to race in the US, mainly thanks to the FAZA Squadra tune applied by driver and team owner Al Cosentino. There is a great story on the man himself, by Road & Track HERE.
As for the livery, I've made it using the restored example in the Revs Institute...
The files compressed in this package modify the Scorpion TC 1.0 Rad mod by Pessio Garage to show the Abarth 1000 TC name and info.
