Three race weekends remain in the IMSA WeatherTech SportsCar Championship season, but not three races for all four of its classes.
While the Prototype and Prototype Challenge classes are off until Monterey and Road Atlanta, respectively, this weekend’s two-hour, 40-minute Michelin GT Challenge at VIRginia International Raceway provides the GT Le Mans and GT Daytona their second of two GT-only standalone showcase events this season (Sunday, 1:30 p.m. ET).
Like last race at Road America, variety has been the spice of life among GTLM winners. Risi Competizione, Porsche North America and Corvette Racing have won at VIR the last three years with the No. 62 Ferrari F458 Italia, No. 911 Porsche 911 RSR and No. 3 Corvette C7.R, respectively.
Each of those three car numbers is somewhat intriguing to note this weekend for different reasons.
Risi’s No. 62 Ferrari 488 GTE is back after a several-race hiatus, the team having withdrawn temporarily after an expensive, crash-laden first half of the season through Le Mans. Out of the championship and with nothing to lose, the capable duo of Toni Vilander and Giancarlo Fisichella can properly play spoiler.
Engineer Rick Mayer describes the challenge of picking the best Michelin tire compound for VIR depending on the temperatures: “Michelin tire selection might come into play here as the track is dark and if its sunny will get very hot, maybe favoring one tire compound over another. All GTLMs have Michelin options that span the temperature window. Predicting weather and the best tire compound could be important if the track temperature is variable.”
The No. 911 Porsche, driven this year by Patrick Pilet and Dirk Werner, remains on the fringe of title contention in GTLM at 22 points back in fifth place and look to complete a sweep of the two GT-only races this year, having delivered the new mid-engined car’s first overall win at Lime Rock Park a month ago.
“I have fond memories of this storied racetrack deep in the heart of America. In 2015, we celebrated one-two finish there with Porsche. It’s an old school circuit with many fast curves where you can’t afford to make one mistake. If you end up on the grass, you might as well drive straight back to the pits to get the radiator cleaned,” Pilet said.
Meanwhile it’s No. 3 Corvette C7.R of Antonio Garcia and Jan Magnussen that, having weathered the storm of a few tough races where the Corvette has not had the Balance of Performance in its favor, maintains the points lead and looks for an encore of its win here last year. Magnussen has matched Garcia as one of the series’ best GT drivers really since this race last year. With Corvette having been given a bit of BoP help this weekend (a 0.5 mm air restrictor increase and an increased fuel flow restrictor), it should help the team get back to its usual race winning contention.
Two sets of pairings – Dirk Mueller and Joey Hand (No. 66 Ford Chip Ganassi Racing Ford GT) and Bill Auberlen and Alexander Sims (No. 25 BMW Team RLL BMW M6 GTLM) – remain within striking distance in points at eight and nine points back (239-231-230) of the lead. The second Ford pairing of Ryan Briscoe and Richard Westbrook needs a bit more help at 14 points back.
Consistency has kept the Alessandro Balzan and Christina Nielsen (No. 63 Scuderia Corsa Ferrari 488 GT3) pairing atop the GT Daytona charts despite not winning a race yet this year. At 15 points clear (254-239) of closest rivals Jeroen Bleekemolen and Ben Keating (No. 33 Riley Motorsports-Team AMG Mercedes AMG-GT3), it’d take a poor finish in the 16-car GTD class to see them lose their grip.
Paul Miller Racing won this race last year, the first and thus far only IMSA win for the Lamborghini Huracán GT3 in the hands of Bryan Sellers and Madison Snow, but its post-qualifying technical violation has all but killed any championship hopes here.
Elsewhere Patrick Long is back alongside Daniel Morad in Alegra Motorsports’ No. 28 Porsche 911 GT3 R, as he was at Lime Rock, while the WeatherTech team continues with its Porsche for a second straight race, 3GT Racing keeps its revised Road America lineups, Michael Shank Racing keeps its revised Road America liveries (albeit with a new frame needed to replace the damaged No. 93 Acura NSX GT3 after accident) and Lone Star Racing continues with its Mercedes-AMG GT3, hoping to start its second race after being unable to with various mechanical niggles at Road America.
“The layout at VIR is an excellent track that makes you feel like you’re really driving somewhere when you’re going around,” explained Mike Skeen, one of Lone Star Racing’s drivers, in this week’s Continental Tire pre-race advance. “It feels like someone just meandered through some fields on a tractor to plan the layout. The result is a great combination of technical corners and flowing, high-speed sections with over 130 feet of elevation change.
“There is plenty of runoff area for the drivers to work with, but all of that beautiful grass proved to be an issue last year for many people that went off course and then had to pit to clean out the grill to avoid overheating. There are also many curbs that we have to use to improve lap times, but they can cause problems if taken too aggressively when the air pressures in our Continental tires are too low.”
Cautions are generally a rarity here with only eight total caution laps over the last three years. Additionally, Lime Rock went caution-free, so it’ll be interesting to see if that cleanliness keeps up.

- In the Continental Tire SportsCar Challenge, a 31-car field heads to VIR for this weekend’s race as well. The GS class points standings are particularly tight with points leaders Dylan Murcott and Dillon Machavern just four points ahead of Cameron Cassels and Trent Hindman, and eight clear of Marc Miller and Till Bechtolsheimer. Miller, who with Danny Burkett took CJ Wilson Racing’s first GS win at this race last year, and his new teammate will have a revised Andy Blackmore Designs livery this weekend with new partner Unit Nutrition adorning the team’s No. 33 Porsche Cayman GT4 Clubsport.
- Military appreciation at race tracks is always a good thing, and will be part of this weekend at VIR. Operation Motorsport is partnering with the USO of North Carolina this weekend at the Michelin GT Challenge at VIR, with the organization hosting 11 wounded soldiers and veterans from the surrounding Raleigh, Ft. Bragg area and embedding them within a few teams so that they can be part of a motorsports experience as a recovery activity. The organization’s website is linked here.
