Two fill-in drivers have been confirmed for the IMSA WeatherTech SportsCar Championship’s next race at Circuit of The Americas, on May 6.
Wolf Henzler will deputize for Kevin Estre in the No. 912 Porsche GT Team Porsche 911 RSR, while Marco Bonanomi will make his IMSA Prototype class debut as a fill-in driver for Tom Kimber-Smith in the No. 52 PR1/Mathiasen Motorsports Ligier JS P217 Gibson.
Henzler will be in the No. 912 car alongside Laurens Vanthoor in GT Le Mans in the first “standard” two-hour, 40-minute race of the season, the Advance Auto Parts Showdown, as Estre will be on FIA World Endurance Championship duty the same day in the WEC 6 Hours of Spa-Francorchamps with Porsche’s GT Team there.
Henzler’s absence means if TRG runs its Porsche 911 GT3 R at COTA in the GT Daytona class, Kevin Buckler would need a replacement for him.
There’s another potential fill-in-for-WEC driver scenario needed if Alegra Motorsports, the Rolex 24 at Daytona winners, were to run in GTD as well. Thus far Carlos de Quesada’s team has run Daniel Morad and Porsche factory driver Michael Christensen in its No. 28 Porsche in GTD through three races, but with Christensen and Estre set to share the No. 92 car at Spa, a replacement would need to be sourced there.
Bonanomi is the second replacement that is confirmed though. The Italian, who made one prior IMSA start since the 2014 merger with Fall-Line Motorsports in an Audi R8 LMS Ultra, will fill-in for “TKS,” who returns to England to take care of his mother, who is battling cancer.
“Tom will unfortunately miss the next race at Circuit of the Americas. He needs to be able to spend time back in the UK with his mother who is presently undergoing treatment for cancer,” said team principal Bobby Oergel.
“As all the drivers who have driven with PR1/Mathiasen Motorsports know, once you’re a part of our team, you’re family, and Tom is a big part of this family. It’s unfortunate that he will miss a round of the championship, but we know that family comes before racing, and we’re happy that he is able to take the time he needs to be with his family during this time.”
“Our thoughts and prayers are with Tom and his mother, and we are praying that she will be cancer free in the near future.”
Bonanomi has tested with the car and will share the car with Jose Gutierrez, who missed Long Beach as Will Owen filled in for him there.
“I was very happy to receive the call from PR1 to drive at their test at COTA. It was my first time driving the Ligier, but I think the test was very positive,” said Bonanomi.
“We tested some set up changes for the race that I think will be very good. The track itself is very demanding on the car and tires, especially with the extreme temperatures that can be present. The first practices during race week will be very critical to get everything just right in terms of set up, but after the test, I think we should be pretty close.”
