This weekend Calan will be competing in the biggest GT event in the world, the Crowdstrike 24 Hours of Spa.
With team WRT, Calan will be racing in the Bronze category with Ahmad Al Harty, Sam De Haan and Jens Klingmann with 21 cars in class. A total of 65 cars will be on track across all categories.
Later today at 3pm local time in Belgium, they will take to the circuit for free practice.
Tomorrow the famous parade of drivers and cars will take place through Spa, with an enormous crowd of fans expected to line the streets.
