Belloc was racing in the Sportsracing world Cup last weekend for Durango (ex F3000 team), and is a sometime ORECA Viper driver.
Riccitelli is driving a Red Bull Porsche GT3 in the FIA GT series.
As for Elliot, Spence and Julian, I remember all 3 from British F3, and the reason they didn't progress was due to being not quite good enough, IMHO.
