Three cars had their times disallowed following post-qualifying technical inspection for the Rolex 24 at Daytona on Thursday night, including the GTD class polesitter.

Two of the three fastest cars in the GTD field, the No. 48 Paul Miller Racing and No. 46 Fall-Line Motorsports Audi R8s, were sent to the rear of the field when officials discovered two different infractions.

For the polesitting No. 48 PMR Audi, the car was found to have a rear wing endplate violation. Meanwhile the No. 46 Fall-Line Audi, which qualified third, was found to have a ride height infraction.

Meanwhile the third-placed Starworks Motorsport Dinan-powered Riley, qualified third in P by Brendon Hartley, was also found to have a ride height infraction and an unapproved aerodynamic device.

The alterations promote Scuderia Corsa to the pole position in GTD, with the No. 63 Ferrari 458 Italia qualified by Toni Vilander. The Finn will co-drive with Alessandro Balzan, Jeff Westphal and Lorenzo Case.

A sister Corsa Ferrari, the No. 65 driven by Daniel Serra, Xandinho Negrao, Marcos Gomes and Francisco Longo, is promoted into second. TRG-AMR’s No. 007 Aston Martin Vantage GT3, driven by James Davison, Al Carter, David Block and Brandon Davis, is now promoted into third.

Everyone from fourth on back in the P class now moves up a position in the 18-car class.
