By 1964, the Lagana had firmly established itself as Erin’s most successful sports car yet, with consistent year-on-year sales that had earned them recognition from even their most toughest of rivals. 1964 too would also see a big increase in sales for the car for one key reason: motorsport.
Erin took the decision in 1962 to enter two race-prepped Laganas into GT +2.0 class of the World Sportscar Championship, up against homologated rivals from the likes of Bonham and Zavir to name a few, expanding their team to a two-division operation alongside their prototype entries. It was a well-executed move, and would lead to 1963’s stunning dual constructors title in both Division III of the manufacturers championship and the sub-3.0l class of the prototypes championship.
