Dixon: Big tire change from 2012 to 2013

0 Comments

Though nowhere near as dramatic – or newsworthy – as Pirelli’s new 2013 compounds have been in Formula 1, the newer compounds Firestone has brought to IndyCar this year have already made an impact on the racing.

Firestone’s primary blacks and alternate reds for Barber Motorsports Park this weekend are both softer than a year ago, and producing higher grip levels. The combo of the grippier tires and the resurfaced Barber track led to record lap times in testing last month.

“We did use the new tire I believe at the Barber Open Test, so those tires haven’t changed as much for the road course, even though the lap times we were about two seconds below pole time of last year,” said Target Chip Ganassi Racing’s Scott Dixon. “We think a lot of that is due to the surface upkeep, that they’ve sort of cut it a little bit or brushed it or something, and the track grip was up a huge amount at the test. So we’ll see if that probably lasts through this weekend, as well.

Dixon’s preference for oversteer (a looser car) was compromised at St. Petersburg.

“St. Pete definitely the street course tire has, for me has changed significantly in being that last year the car, we were constantly fighting sort of issues with rear grip,” he said. “I love to drive a loose car, so I think it sort of helped me, the new car last year with the combination of the tire. This year it’s a lot of rear grip, a lot of understeer. It seems like it wears the front tires off a lot quicker, as well. So we haven’t kind of seen that quite as much at the Barber test that we did have.”

For Barber, Dixon said the difference between Firestone’s two compounds need to be different enough to ensure as good a race as occurred last year.

“Maybe with the warmer temperatures going back a month or so later; I think the track was pretty cold then, so we were looking at 20 or 30 degrees warmer for this race weekend, which may change a little bit,” he admitted.

“But yeah, I guess the red tires were pretty key to last year and the great racing that we have. I think it’s important that Firestone work on that,” he said. “We see how the Formula 1 races go, and Pirelli are getting a little bit of flak, but the racing is fantastic. It’s more in the driver’s hands of managing the tires, looking after them, making sure they can get through a whole stint, teams working out strategies to figure out ways to get to the end quicker. It creates a lot of differences between teams and drivers and that creates racing on track.

“This weekend is a little bit unknown just because it’s the first road course race of the year. I hope there’s still quite a bit split between the reds and the blacks. I think at St. Pete it almost seemed like the gap between the reds and blacks was a lot less. I know they’re normally quite conservative at the start of the year, Firestone, to make sure we have a durable tire, but hopefully for me I’d hope that the reds fall off quickly and you have to really maintain a smart pace and a setup and manage the car well throughout the racing stint.”

DAYTONA BEACH, Fla. — The 2023 Rolex 24 at Daytona overall results were all streaks: two consecutive victories in the endurance classic for Meyer Shank Racing and three in a row for Acura.

And Helio Castroneves became the second driver to win three consecutive Rolex 24s and the first to win in three straight years (Peter Gregg won in 1973, ’75 and ’76; the race wasn’t held in ’74 because of a global oil crisis).

Starting from the pole position, Tom Blomqvist took the checkered flag in the No. 60 ARX-06 that led a race-high 365 of 783 laps with co-drivers Castroneves, Simon Pagenaud and Colin Braun.

Meyer Shank Racing now has two Rolex 24 victories and the 2022 championship since entering the premier prototype category of the IMSA WeatherTech SportsCar Championship in 2021.

“I think what’s so special about this team is we are a small team compared to some of our opponents, but the atmosphere, the way we work, enables people to get the best out of themselves, and I think that’s why we’re such high achievers,” Blomqvist said. “I think there’s no egos. It’s a very open book, and that just enables each and every one of us to reach our potential. I think that’s why we’ve achieved so much success in really a short time at this level of competition.”

It’s the 16th IMSA victory for MSR.

The 61st running of the Rolex 24 at Daytona marked the debut of the Grand Touring Prototype category that brought hybrid engine technology to IMSA’s top level.

In other categories:

LMP2: James Allen passed Ben Hanley on the final lap and delivered a victory in the No. 55 ORECA by 0.016 seconds. It’s the second IMSA victory for Proton Competition, which last won at Sebring in 2012. It was the first Rolex 24 victory for Allen and co-drivers Gianmaria Bruni, Fred Poordad and Francesco Pizzi.

GTD Pro: Cooper MacNeil won in the last start of his IMSA career as the No. 79 Mercedes-AMG GT3 scored the first Rolex 24 at Daytona for WeatherTech Racing and the team’s fourth career victory.

MacNeil, who co-drove with Maro Engel, Jules Gounon and Daniel Juncadella, earned his 12th career victory and first at the Rolex 24.

“Winning by last IMSA race is tremendous,” MacNeil said.

GTD: The No. 27 Heart of Racing Team delivered the first Rolex 24 at Daytona for Aston Martin, which has been competing in endurance races at Daytona International Speedway since 1964. Drivers Marco Sorensen, Roman De Angelis, Darren Turner and Ian James (also the team principal) earned the victory in the English brand’s 13th attempt.

It’s also the first Rolex 24 at Daytona win for Heart of Racing, which has seven IMSA wins.

LMP3: Anthony Mantella, Wayne Boyd, Nico Varrone and Thomas Merrill drove the No. 17 AWA Duqueine D08 to victory by 12 laps for the team’s first class win in IMSA.
