Part four of my Rolex 24 preview looks at the GTD class, open to GT3 machinery. If you would like to view my other class previews, you can find DPI here, LMP2 here and GTLM here. The GTD class is by far the biggest in the race, with 18 entries from nine different makes.

The class focuses on pro/am racing, similarly to LMP2, with the focus being on pairing amateur drivers with professionals. With 18 entries and nine different cars, the class will provide intense racing the entire 24 hours. Let’s preview the first half of this GTD class.

#9 Pfaff Motorsport Porsche 911 GT3 R: Lars Kern/Dennis Olsen/Patrick Pilet/Zach Robichon

Pfaff Motorsport return to IMSA, aiming to improve upon a very good 2019 season. Two wins at Lime Rock and Road America propelled the team to third in the GTD standings. Porsche’s renewed focus on GT racing has massively improved their 911 GT3 car across the world.

Canadian Zach Robichon impressed last year and so returns for the full season, partnered with Dennis Olsen. Porsche factory drivers Lars Kern and Patrick Pilet complete the line-up for Daytona.

Qualifying at the Roar didn’t go to plan, with Robichon placing the Porsche 14th. The team ran consistently during the test without any issues. The pace wasn’t there, except when Pilet was in the car, but don’t discount them. The Porsche is a proven package and their driver line up deserves respect.

#11 GRT Grasser Racing Lamborghini Huracan GT3 Evo: Albert Costa/Richard Heistand/Franck Perera/Steijn Schothorst

De facto Lamborghini factory team GRT Grasser Racing have made the switch to IMSA  this year, after impressive cameo appearances in recent seasons. The team are twice defending Rolex 24 champions, along with a Sebring 12 Hours class win last year. Despite only running the Michelin Endurance Cup rounds, the team are a formidable opponent.

Lamborghini factory aces Albert Costa and Franck Perera lead the team, joining very quick silver rated driver Steijn Schothorst. Richard Heistand moves across from Lexus to complete the quartet.

The car ran quickly at the Roar in the hands of Costa and Perera, with Heistand going ninth in the qualifying session. The team have a proven pedigree in Europe, and recent years have shown that the Lamborghini is ideally suited to Daytona.

#12 AIM Vasser Sullivan Lexus RC F GT3: Townsend Bell/Shane van Gisbergen/Frankie Montecalvo/Aaron Telitz

AIM Vasser Sullivan return for a second year running the Lexus GT3  program, after a promising debut season. The team came a close second at the Rolex 24 last year with this #12 car.

Townsend Bell and Frankie Montecalvo return, with Indy Lights star Aaron Telitz also back as the third driver. Completing the team is Australian V8 Supercars star Shane van Gisbergen. His signing is a real coup for the team, as he embarks on his fifth Rolex 24.

Montecalvo topped the Roar qualifying session, a boost for the team heading into the race. He was consistently quick in the car, with a faultless three days another promising sign. They have all the ingredients to go one better than their second last year.

#14 AIM Vasser Sullivan Lexus RC F GT3: Kyle Busch/Parker Chase/Michael de Quesada/Jack Hawksworth

The #14 car has created headlines this year, thanks to signing Nascar superstar Kyle Busch for his Rolex 24 debut. The team showed enormous promise last year, with third in the Sprint Cup and two wins in a stellar debut year.

Jack Hawksworth returns, this time partnered with Parker Chase. 2017 Rolex 24 GTD winner Michael de Quesada joins for the Endurance rounds, along with Busch.

Hawksworth did a masterful job to top the opening Roar test session by three tenths of a second, a big gap in this class. From here the test was used to get the others up to speed. De Quesada and Busch had never driven the car before. The team has a great line-up, they just need more time in the car

#16 Wright Motorsport Porsche 911 GT3 R: Klaus Bachler/Ryan Hardwick/Anthony Imperato/Patrick Long    

Wright Motorsport steps across into IMSA from the Blancpain GT World Challenge America. The team do have prior experience of the Rolex 24.

Porsche factory driver Patrick Long joins Ryan Hardwick for the season, with Anthony Imperato joined by fellow Porsche factory ace Klaus Bachler for this race. Imperato was with the team in Blancpain last year, with Hardwick moving across from Paul Miller Racing.

Long put the car in the top five for the Saturday night session at the Roar, however Imperato struggled in the qualifying session. 17th and 1.2 seconds back is tough, but the test is about gaining experience and the team ran smoothly throughout.

#19 GRT GEAR Racing Lamborghini Huracan GT3 Evo: Tatiana Calderon/Rahel Frey/Katherine Legge/Christina Nielsen

The second GRT entry falls under the GEAR Racing banner. GEAR are promoting women in motorsport, starting in IMSA. The initiative aims to expand into other forms of motorsport, and has already garnered plenty of publicity.

Katherine Legge moves across after three successful years with Michael Shank, and is joined by former double class champion Christina Nielsen. Completing the all female line-up is experienced GT racer Rahel Frey and F2 convert Tatiana Calderon.

The car completed over 160 laps across the three day Roar test, as all four driver get used to a new car. The Lamborghini package is competitive at Daytona, so gaining as much experience as possible before the race will be key.

#23 Heart of Racing Team Aston Martin Vantage AMR GT3: Roman de Angelis/Ian James/Alex Riberas/Nicki Thiim 

The popular Heart of Racing team return to IMSA after a three year absence. The team raises money for Seattle Children’s hospital and has raised over $6 Million since 1997. Their Aston Martin Vantage GT3 car is making it’s IMSA debut, the first Aston Martin customer IMSA program in several years.

Alex Riberas returns to the team, joining reigning Porsche GT3 Cup American and Canada champion Roman de Angelis. Team manager Ian James joins for the endurance rounds, with factory driver Nicki Thiim along for Daytona.

The team never troubled the top of the times during the seven test sessions, but they did run consistent lap times without issues. Thiim is the only one with experience of this car, so the team has a lot to learn in a short space of time. Simply finishing the Rolex 24 would be a great result.

#44 GRT Magnus Racing Lamborghini Huracan GT3 Evo: Andy Lally/Marco Mapelli/John Potter/Spencer Pumpelly 

The third GRT Grasser run entry is this #44 car, which takes on Magnus Racing branding after the popular team disbanded last year. The team were mainstays of IMSA, but return with new support.

Magnus team owner John Potter returns, along with long time co-driver Andy Lally. Spencer Pumpelly joins for the endurance races, with factory driver Marco Mapelli recruited for Daytona.

The #44 team were consistently at the top during the Roar. Amateur driver Potter struggled in the qualifying session, but the car was very quick in the other drivers hands. The team were tenth last year, but as former two-time winners of the Rolex 24 this entry cannot be discounted.

#47 Precision Performance Motorsport Lamborghini Huracan GT3 Evo: Brandon Gdovic/Johnathan Hoggard/Mark Kvamme/Eric Lux

PPM Motorsport return for another year of IMSA competition with their #47 Lamborghini Huracan GT3. The team only ran the Michelin Endurance Cup rounds last year, their second in IMSA after moving across from Nascar.

The owners son Brandon Gdovic returns, with Eric Lux joining after partial seasons in the LMP2 class. Johnathan Hoggard and Mark Kvamme were late additions from the aborted Rick Ware Racing LMP2 entry. Hoggard is the Sunoco Challenge winner, and as a British F3 race winner should be quick despite a lack of experience.

Gdovic impressed at the Roar, qualifying fourth, less than two tenths from top spot. Lux didn’t complete any laps, losing valuable driving time as he adjusts to GTD. Based off testing times, this #47 car could surprise a lot in the paddock.

#48 Paul Miller Racing Lamborghini Huracan GT3 Evo: Andrea Caldarelli/Corey Lewis/Bryan Sellers/Madison Snow

Paul Miller Racing return for a fifth season with their Lamborghini Huracan. The team won at Laguna Seca last year. Problems last year limited them to 15th at the Rolex 24, a result they can improve upon.

Bryan Sellers and Madison Snow return, aiming to repeat their 2018 IMSA GTD title. Corey Lewis is back for the endurance rounds, with factory pilot Andrea Caldarelli also back for Daytona.

Caldarelli and Sellers had the car running competitive laps at the test, although Snow will be disappointed with 13th in qualifying. This team are looking to bounce back and repeat their 2018 form.
