IMSA has penalized the second-place Land Motorsport GT Daytona team for a minimum drive-time infraction from last weekend’s Rolex 24 At Daytona.

The penalty moves the No. 29 Audi R8 LMS GT3 to the back of the GTD field in the official results, promoting the No. 12 AIM Vasser Sullivan Lexus RC F GT3 to second in class and elevating the No. 88 WRT Speedstar Audi Sport entry to third.

Land driver Ricky Feller was found to be afoul of the drive-time rule, which specifies the minimum and maximum amount of time drivers must spend behind the wheel to earn points and, in this instance, comply with the rulebook. In a class like GTD where a mix of professional and amateur drivers share each car, the drive-time regulations are used to ensure the professional do not fill the majority of the available seat time while also safeguarding the interests of the amateurs whose time in the car might otherwise be reduced to the smallest number possible.

According to a statement from IMSA, “Minimum drive-time for the GTD class at the Rolex 24 was four hours, 45 minutes and base drive-time was three hours, 30 minutes. Both times were reduced by a percentage commensurate to the time lost while drive-time was stopped for red flags during the event.”

Citing the sporting regulations that govern drive-time requirements, IMSA added more specifics to the situation with Land’s Feller: “Two drivers rated silver and/or bronze must individually achieve the minimum drive-time and each other driver (regardless of Driver rating) must individually drive the car for a base drive-time as listed in the SR or Car penalized in the drive-time penalty order priority.” It’s believed Feller was 15 minutes short of meeting the minimum drive-time obligation.

Scuderia Corsa’s Toni Vilander was also penalized for a drive-time infraction. Having crashed late in the race, his No. 63 Ferrari 488 GT3 was classified 14th in GTD and was not running at the finish. The No. 63 has also been moved to the bottom of the results.
