The Moroccan Grand Prix returned in 1957, but it was ran to Formula One regulations and local competitors could not afford to enter. The event organisers remedied this for the 1958 event, allowing Formula Two cars to enter in a separate class. La Caze secured an F2 entry with a privately owned Cooper. He lacked open-wheel racing experience, but impressed in practice by lapping within two seconds of the F2 class leaders. He qualified fourth out of the F2 entries and steadily improved throughout the race, making a late pass on André Guelfi to secure third in the F2 class and 14th overall. However, the race was marred by Stuart Lewis-Evans' accident which ultimately proved to be fatal, and the Moroccan Grand Prix would not return.
