The American brand last secured a class success at La Sarthe in 2015, despite coming close in several editions since then - including having two cars in GTE Pro victory contention last year before neither ultimately finished.
Now, with the Chevrolet Corvette C8.R GTE's final appearance in the enduro coming with a sole GTE Am entry this weekend, Catsburg says there is a strong focus on returning to winning ways ahead of the introduction of the LMGT3 class for 2024.
"We had high expectations the last two years and I guess the expectations are even higher this year," he told Autosport.
"We're all very anxious and we really want to win this one."
Asked if there was added pressure to secure the spoils this year, Catsburg said: "I would say so. It's in the back of my mind, that this is the last shot at GTE.
"It's also the one endurance race that I'm missing on my CV. I would love to add it."
