IMSA’s premier sportscar series makes its racing debut at the tight and twisty 1.654-mile, nine-turn temporary street circuit in downtown Detroit on Saturday, with its GTP and GTD Pro classes making up a 21-car field.
Tandy won the pole from Porsche Penske Motorsport team-mate Dane Cameron by 0.124s in qualifying on Friday afternoon, and although his time was 3.7s quicker than the fastest GTD Pro car, the difference in the way the classes make their lap time will pose a unique challenge when it comes to lappery.
