Most notably, the maximum stint length in GTWC America has been changed from 50 to 65 minutes, and extended from 55 to 70 minutes in the event a stint occurs during a full-course caution. ***This change, which now falls in line with SRO Motorsports Group’s global sporting r...

Photo: Mike Levitt/IMSA The Acura ARX-06 has received the smallest Balance of Performance break for next weekend’s StubHub Monterey SportsCar Championship at WeatherTech Raceway Laguna Seca. Released in the latest Balance of Performance tables on Thursday, the Meyer Shank Racing-run prototypes have only received a 3 kg weight break since its victory at Long Beach, with BMW, Cadillac and Porsche all getting double-digit decreases. While the Aston Martin Valkyrie remains at the 1030 kg baseline, the BMW M Hybrid V8 receives a significant 17 kg weight reduction, while the Cadillac V-Series.R gets a 15 kg weight break and the two specification Porsche 963s also shed considerable weight in the form of 16 kg (2026) and 8 kg (2025), respectively. At 1084 kg, the factory Porsche Penske Motorsport entries are still the heaviest GTP cars, by 28 kg compares to the next heaviest, which is the Acura. It’s believed the significant weight shifts for the LMDh-based cars are to work around the...

Photo: Shea Holbrook BSI Racing arrived on time at Circuit of The Americas despite its transporter having suffered a fire and one of its Toyota GR 86 Cup cars damaged. The Daytona Beach, Fla.-based team, which fields six cars in the SRO America-run single-make series, faced the significant setback on Monday just ten minutes outside of its workshop on I-95 en route to Austin. Volusia County firefighters, who were on their way to a training exercise, were able to put the fire out that saved the team from a “much worse outcome” according to team owner Shea Holbrook, who said nobody was injured in the accident. “To the hundreds of you who reached out, offered trailers, or checked in on us, thank you!” Holbrook wrote in a post on Instagram. “We were completely overwhelmed by the kindness of the racing community. From competitors stopping roadside to the flood of messages in our inbox, your support is simply incredible. “What happened next is a testament to the BSI crew. “On the sho...

Acura Confirms ‘Pausing’ of IMSA GTP Effort at End of Year

Image
Photo: Brandon Badraoui/IMSA Acura has officially confirmed its exit from the IMSA WeatherTech SportsCar Championship at the end of the season. The news, announced on Wednesday, follows Sportscar365’s report last week that the luxury automaker was set to end its factory GTP program, amid significant financial losses from parent company Honda in relation to EV sales. In a statement, Acura said that it will “pause” its IMSA GTP program, while pivoting the brand to an increased effort in the NTT IndyCar Series, with Acura sponsorship set to be on Marcus Armstrong’s Meyer Shank Racing-entered entry in this year’s Indianapolis 500. No word has been made regarding the possibility of seeing the ARX-06s run by customers either next year or in the future. Additionally, a reason for the halting of its sports car racing program was not given. “We are extremely proud of what we’ve accomplished during this era of Acura prototype racing which began back in 2018 with the introduction of the...

34 Entries for Laguna Seca as GTD Pro Returns to Action

Image
Photo: Mike Levitt/IMSA A total of 34 entries are set for next weekend’s Monterey SportsCar Championship, the fourth round of the IMSA WeatherTech SportsCar Championship season. Following a GTP-GTD only sprint race on the streets of Long Beach, the GTD Pro class returns to action for next Sunday’s first two-hour and 40-minute race of the season. The GTD Pro class will feature nine entries for its first sprint outing of the season, all consisting of full season teams. Co-championship leaders Manthey Racing, as expected, has not altered its plan of contesting the Michelin Endurance Cup-only races with its Nos. 911 and 912 Porsche 911 GT3 R Evos not on the Laguna entry list. It means Paul Miller Racing’s Connor De Phillippi and Neil Verhagen will enter the event with an effective 30-point lead over Corvette Racing by Pratt Miller Motorsports’ Nicky Catsburg and Tommy Milner. The 11-car GTP class is largely unchanged from Long Beach, which was won by the No. 93 Meyer Shank Racing...

Rinicella won the 2024 Asian Le Mans Series title and is making a full-time switch from single-seaters to sports cars this season, with his main program being in the European Le Mans with IDEC. He finished fourth in the season opener in Barcelona earlier this month alongside Jamie Chadwick and Laurents Hoerr in the Genesis-backed car . He has now been confirmed as tackling Le Mans with class stalwarts Lafargue and van Uitert, who previously finished on the podium together with IDEC in 2024. Rinicella described competing at Le Mans as “a childhood dream coming true” and added: “For a first-time entry, there’s obviously a lot of excitement, but also a bit of pressure. “It’s a race with very experienced drivers, so I still have a lot to learn, esp...
