Friday 5: 23XI Racing takes different approach to building pit crews


At 33 years old, Josh Shipplett envisioned spending another five years as a tire carrier on pit road. But when 23XI Racing decided to have its own pit crews rather than contracting them from Joe Gibbs Racing, it changed Shipplett’s plan.

He became the team’s pit coach and was charged with building 23XI Racing’s pit crew program.

“Coaching opportunities in this series don’t come available every day,” Shipplett told NBC Sports. “To be able to do it from scratch and build something the way that 23XI believed in and I also believed in, I knew it was going to be hard, but in my thoughts it would have been a lot harder to go somewhere else and change a philosophy they already had.

“To have this opportunity to start from new and have the coaching opportunity was something that probably wasn’t going to happen, so I had to jump on it.”

The performance of 23XI Racing’s Bubba Wallace and Tyler Reddick and their pit crew will be among the key storylines this season. 

Co-owner Denny Hamlin has said that a goal is to have both cars in the playoffs this season. The pit crew’s execution will be key to that. Last year, 23XI Racing’s pit crews struggled at times. A more consistent unit could help Wallace and Reddick win more often.

Shipplett is used to winning. His first Cup race as a tire carrier came in the 2011 Daytona 500 with Wood Brothers Racing, which won that day with Trevor Bayne. Shipplett also was the tire carrier when Hamlin won the 2019 and ’20 Daytona 500s. Shipplett served as tire carrier for 23XI Racing’s No. 45 car last year and was a part of Kurt Busch’s winning crew at Kansas.

Hiring a pit crew member without coaching experience to lead a new program could be viewed as a gamble, but 23XI Racing didn’t see it that way.

“I think it is part of how we are looking at everything here,” Steve Lauletta, president of 23XI Racing, told NBC Sports. “We have an engineer that worked in DTM (German grand touring car series). We have a mechanic from Formula One. It’s the way Denny is looking at it. This is where his input is so beneficial. He’s been around it long enough and he has a vision of how he wants the leadership and the people here to work together, collectively as one team in 23XI.

“I think he’s got a good eye at picking talent. It doesn’t mean how many teams have you worked for, it’s can you do what we want to do here? Can you look at it a different way? Can you innovate how it’s done? What’s your approach rather than what’s your experience.”

One of the major changes Hamlin wanted to make with the pit crew this season was to have more experienced team members.

“We will continue to develop younger talent down the pipeline, but we don’t have the time to develop them at the racetrack,” Hamlin told NBC Sports. “We need the results now and quickly. We want to continue on a good trajectory.”

Shipplett recruited those who had that experience. Only three of the 10 pit crew members were with 23XI Racing last year. Others came from Hendrick Motorsports, Team Penske, Richard Childress Racing and Joe Gibbs Racing.

Wallace’s pit crew is new from what he had at the start of last year: Front tire changer Austin Dickey, rear tire changer Adam Hartman, tire carrier Brad Donaghy, jackman Jordan Paige and fueler Josh Pech. Only Paige was with 23XI Racing last year, serving on the No. 45 car.

Reddick’s pit crew will be front tire changer Houston Stamper, rear tire changer Brian Bottlemy, tire carrier Wade Moore, jackman Nathan Ricketts and fueler Brian Dheel. Only Dheel and Stamper started last year with 23XI Racing.

The Joe Gibbs Racing and 23XI Racing pit crews debuted a new way to service a car last year.  Previously, the front tire changer changed right front and then moved to the left front and replaced that tire, while the rear tire changer did the same at the back of the car. 

In the new pit style, the front tire changer on the right side runs to the rear tire on the left side and changes it. The rear tire changer on the right side runs to the left front and changes that tire. 

“From the time to you leave the (pit) wall to the time the car drops, everything’s 100 miles an hour,” Shipplett said of the new pit style. “Nothing ever slows down. There’s never that point in the stop where you can say, ‘OK, I did my job right here, let’s move to the next step.’ It all just blurred together. I think that’s what caused a lot of issues.”

The new way of pitting a car was faster but any hiccup could adversely affect the stop, costing seconds and track position. 

Shipplett said that while the team has practiced the newer style of pitting a car, “it’s definitely not the primary focus.”

Instead, he would rather have consistent stops. The key is positions gained on pit road. Shipplett noted that if a pit crew has three nine-second pit stops and a final stop of 12 or more seconds, the team is likely to lose more positions in that slower stop than they gained together on the three faster stops.

“Let’s have that (good) average,” Shipplett said of an average time per pit stop, “but let’s not do it by having three really fast stops and then a catastrophic failure.”

While he’s not been a coach before, his experience on pit road will help the 23XI Racing crews.

“You’ve lived it,” Shipplett said. “You can see where people are pushing maybe where they shouldn’t be pushing.”

Shipplett also is training with the pit crews because he will be the tire carrier for Travis Pastrana’s car. Pastrana is driving the No. 67, a third entry for 23XI Racing at Daytona. He is not guaranteed a spot in the Daytona 500 and must earn it through qualifying or his qualifying race. 

While Hamlin has said he plans to have a car ready for Kurt Busch should Busch want to race it once he’s cleared after his injury last summer, there aren’t plans to run the No. 67 car beyond Daytona at this point. The focus will remain on the pit crews for Wallace and Reddick.

2. No change for Trackhouse Racing

Trackhouse Racing owner Justin Marks said earlier this week on SiriusXM NASCAR Radio that “we’re not interested” in joining Toyota.

His comments come in light of David Wilson, president of Toyota Racing Development, recently telling NBC Sports of Toyota’s interest in expanding its Cup lineup in 2024.

“Our relationship with Chevrolet is so important to us,” Marks said on “SiriusXM Speedway” this week. “We’ve tethered ourselves to the trajectory, to the commitment, to the passion that they’ve got for this sport.

“They’ve obviously made a huge investment with their tech and innovation center in Concord, North Carolina, supporting their key partner teams. We’re one of three teams that are the key partners, right alongside (Richard Childress Racing) and Hendrick (Motorsports), which is an incredibly valuable relationship for us. … I think more Toyotas on the racetrack would be good for David and good for his group over there, it just won’t be with Trackhouse.”

3. Advice for Jimmie Johnson

Next week at Daytona will mark only the second time that seven-time Cup champion Jimmie Johnson has driven the Next Gen car. He drove it for a day at a Phoenix test in January.

With no Cup practice before the qualifying races, the only laps Johnson will have in the car at Daytona will be his qualifying laps on Wednesday. The qualifying races are on Thursday. Johnson, co-owner of Legacy Motor Club, is one of six drivers vying for four spots available to non-chartered cars. 

“He’s already been asking some questions about superspeedway racing with these cars,” teammate Erik Jones said. “I know he’s doing his homework.”

What has Jones told Johnson about how these cars are on a superspeedway?

“Just the way these cars draft is so different. … It’s harder to move up through the pack,” Jones said. “I felt like with the old car, especially the last year or two, you could make some big moves and aggressive moves. They were risky, but you could put yourself back in position pretty quickly to get in the spot you want to be in to try to win the race.

“With this car, if you’re not up in the top four at the end of it, I don’t feel like you have a chance, really, unless something kind of crazy happens towards the end of the race. I think you have to race more than ever. You have to have a fast car more than ever.”

4. Mufflers 

Last weekend’s Clash featured mufflers on the Cup cars. There remains some work to do.

The mufflers reduced the sound of the cars slightly but the rumble remained for those who like the loud noise.

One aspect of the mufflers, though, is that some drivers talked about how hot it was inside the car.

“It was extremely hot with the mufflers,” Chase Briscoe said after the Clash. “I was getting pretty fumed out bad.”

Justin Haley said he and Kaulig Racing teammate AJ Allmendinger didn’t have any issues with fumes or heat last weekend.

Corey LaJoie said he thought the mufflers worked well.  

“I like the sound,” he said of the car with a muffler. “I like kind of knocking that ear-piercing noise out of it. I feel like we could package it better than they are now. It looks like we’re trying to fit 10-pound mufflers into a five-pound rocker box at the moment. I think there’s a way to be able to do that and make it look cleaner.

“I know that some guys complained about (carbon monoxide) fumes and stuff like that, which might be a case of just that small track because you’re not getting a whole lot of air circulating in the Coliseum.”

The next time mufflers are scheduled to be on the cars is for the July 2 Chicago Street Race.

5. Super Bowl and Daytona 500

Sunday’s Super Bowl matches the Kansas City Chiefs vs. the Philadelphia Eagles. For NASCAR fans, the game could provide a clue as to who might win the Daytona 500.

Four times since 2016, the margin of victory in the Super Bowl was 10 or more points. Three of those years, Denny Hamlin won the Daytona 500.

The last time Kansas City won the Super Bowl was 2020. Denny Hamlin scored his third Daytona 500 win that year.

The last time Philadelphia won the Super was 2018. Austin Dillon won the Daytona 500 that year.

The last time a player other than a quarterback or wide receiver won the Super Bowl MVP award was 2016. Hamlin won the Daytona 500 that year.

Dr. Diandra: With Chase Elliott out, these are the best Next Gen road racers


The Next Gen racecar is the ideal vehicle for road course racers. With none of the asymmetry of previous car generations — vehicles optimized for only turning left — the new car upended the road course pecking order.

Road course ace Chase Elliott will watch this season’s first road course race from the sideline while recovering from a fractured left leg.

Elliott has won seven of the 25 Cup Series road courses races he’s run, giving him a win rate of 28.0%. That’s a little more than one win in every four races. He posts top-10 finishes 68.0% of the time.

In 2022, Elliott:

  • led the most laps (121) at road courses
  • led four of the six road course races
  • led the most laps at three of the six road course races

But he didn’t win any of them.

Tyler Reddick won on two road courses, including his first Cup Series win on the way to a three-win season. Ross Chastain, Daniel Suárez, Kyle Larson, and Christopher Bell each won one race.

Winning isn’t everything… but it’s a start

The unusually high number of spins and tire/wheel issues last year means that finishes don’t always reflect how well a driver ran.

For example: Elliott led most of the first two stages at Sonoma but had to back up during a mid-race pit stop to retighten a wheel. His average running position was 2.2 before the glitch and 15.9 after. He finished eighth.

Despite not winning in 2022, Elliott still tied for the best average finishing position on road courses. The graph below shows all drivers with average finishing positions below 12 in 2022.

A vertical bar chart showing the most consistent Next Gen road course racers

Of last year’s road course winners, only Reddick and Bell make the graph.

  • Three finishes outside the top 20 drop Chastain’s average finish to 16.7.
  • Sonoma winner Suárez had three top-five finishes and three finishes of 24th and worse for an average finish of 16.5.
  • Although Larson finished third at Road America and won Watkins Glen, his other four finishes were 29th or worse. That averages out to 19.7.

That’s not to say these drivers aren’t contenders for a win at any road course race. But I’m more interested in the most consistent Next Gen road course racers.

Only four drivers have average finishing positions under 10: Elliott, Reddick, Chris Buescher and Austin Cindric. Michael McDowell is fifth on the list, 1.3 positions back from Reddick. Bell is 0.7 positions behind McDowell.

Going beyond averages

To gain insight, I examined driver finishes by track, as shown in the graph below. Average positions are represented by gray bars, with symbols showing individual race finishes.

A scatter plot showing 2022 road course finishes by race for 2022's best Next Gen road racers
Symbols overlaps when a driver had two finishes in the same place. For example, Tyler Reddick won twice, so the two symbols are overlaid.

This graph shows, for example, that Elliott had four top 10s and two finishes out of the top 15. Buescher had the same average finishing position but had five top 10s and one 21st-place finish.

Given the issues the new car introduced, this graph suggested that I give each driver a mulligan. So I also calculated the average of each driver’s best five road course races and summarized them in the table below.

A table comparing average finishes for 2022's best next-gen road course racers

Let’s look a little deeper into three of these drivers.

Chris Buescher

Buescher won the fall Bristol race and his name always comes up when talking superspeedways.

But the Next Gen car improved Buescher’s average road course finish by 3.1 positions relative to 2021. Buescher not only matches Chase Elliott’s average finish but beats Elliott in number of top-10 finishes.

If we throw out both drivers’ worst finishes — a 21st-place at COTA for Buescher and Elliott’s P20 at the Roval — Buescher beats Elliott in average finish position.

Austin Cindric

Cindric won four road courses in the Xfinity Series and posted the third-best average finish at road courses in his first Cup Series season. His 2022 performance included four top-10 finishes on the first four road courses of the season.

But even excluding his 21st-place finish at the Roval, Cindric remains ranked behind Elliott and Buescher.

Like Buescher, Cindric’s average running position is significantly higher than his average finishing position. That raises the interesting question of whether drivers advancing last year did so because they were better in the Next Gen car, or because other drivers had trouble.

Tyler Reddick

Reddick finished 35th at Sonoma last year, 13 laps down. He had been running consistently in the top six before requiring a brake repair.

But Sonoma was Reddick’s only misstep. His other five road course finishes were all top 10s, including two wins. Excluding the Sonoma finish gives Reddick a 4.4 average finishing position for 2022 road courses — the best of any driver.

Reddick’s move from Richard Childress Racing to 23XI raises some questions about how his 2023 road course performance will compare with 2022. Excepting last week at Atlanta where an ailing Reddick finished fifth, Reddick has finished the same or worse than last year. And that’s with an additional year of experience in the Next Gen car.

It’s just as hard to predict winners this year as it was last year. But if you’re looking for drivers who can reliably finish in the top 10, these are the best choices.

North Wilkesboro’s worn surface will prove challenging to drivers


NORTH WILKESBORO, N.C. — Three Cup drivers got their first chance to experience North Wilkesboro Speedway’s worn racing surface Tuesday and said tires will play a key role in the NASCAR All-Star Race there on May 21.

Chris Buescher, Austin Dillon and Tyler Reddick took part in a Goodyear tire test Tuesday. That test was to continue Wednesday.

The verdict was unanimous about how important tire wear will be.

“This place has got a lot of character to it,” Reddick said. “Not a lot of grip and it’s pretty unforgiving. It’s a really fun place.”

Dillon said: “If you use up your tire too early, you’re going to really be in trouble. You really got to try to make those four tires live.”

Buescher said: “The surface here was so worn out already that we expect to be all over the place. The speeds are fairly slow just because of the amount of grip here. It’s hard to get wide open until you’re straight.”

Reddick noted the drop in speed over a short run during Tuesday’s test. That will mean a lot of off-throttle time.

“I think we were seeing a second-and-a-half falloff or so over even 50 laps and that was kind of surprising for me we didn’t have more falloff,” he said. “But, one little miscue, misstep into Turn 1 or Turn 3, you lose a second sliding up out of the groove and losing control of your car.”

“That’s with no traffic. Maybe with more traffic and everything, the falloff will be more, but certainly we’re out of control from I’d say Lap 10 on. You have to really take care of your car. … It’s really hard 30-40 laps into a run to even get wide open.”

One thing that stood out to Dillon was how the facility looks.

While the .625-mile racing surface remains the same since Cup last raced there in 1996, most everything else has changed.

In some cases, it is fresh red paint applied to structures but other work has been more extensive, including repaving the infield and pit road, adding lights for night racing, adding SAFER barriers, the construction of new suites in Turn 4 and new stands along the backstretch.

“It’s cool to see how much they’ve done to the track, the suites, the stands that they’re putting in,” Dillon said. “To me, the work that is going in here, we’re not just coming for one race. We’re coming here for a while. I’m excited about that.”

Drivers to watch in NASCAR Cup race at COTA


Sunday’s NASCAR Cup Series race at Circuit of the Americas in Austin, Texas, has attracted an entry list that includes talent beyond that of the tour regulars.

Jordan Taylor, who is substituting in the Hendrick Motorsports No. 9 Chevrolet for injured Chase Elliott, brings a resume that includes 31 IMSA class wins, two 24 Hours of Daytona overall wins and two IMSA wins at COTA.

Jenson Button won the Formula One championship in 2009 and has five F1 starts at COTA. He is scheduled to be a driver for the NASCAR entry in this year’s 24 Hours of Le Mans.

Kimi Raikkonen, entered by Trackhouse Racing as part of its Project 91 program, won the 2007 F1 championship and has eight F1 starts at the Austin track.

They will draw attention at COTA this weekend, along with these other drivers to watch:


Brad Keselowski

  • Points position: 5th
  • Best seasonal finish: 2nd (Atlanta I)
  • Past at COTA: 19th and 14th in two career starts

Keselowski hasn’t been a star in road course racing, but his 2023 season has started well, and he figures to be in the mix at the front Sunday. He led the white-flag lap at Atlanta last Sunday before Joey Logano passed him for the win.

AJ Allmendinger

  • Points position: 17th
  • Best seasonal finish: 6th (Daytona 500)
  • Past at COTA: 5th and 33rd in two starts

The Dinger is a road course expert. Last year at COTA, he was involved in tight racing on the final lap with Ross Chastain and Alex Bowman before Chastain emerged with the victory.

Ross Chastain

  • Points position: 3rd
  • Best seasonal finish: 3rd (Auto Club)
  • Past at COTA: Two straight top fours, including a win

Chastain lifted Trackhouse Racing’s profile by scoring his — and the team’s — first Cup victory at COTA last season. He’s not shy about participating in the last-lap bumping and thumping that often mark road course races.


Chris Buescher

  • Points position: 13th
  • Best seasonal finish: 4th (Daytona 500)
  • Past at COTA: 13th and 21st in two starts

Buescher has never led a lap at COTA and is coming off a 35th-place finish at Atlanta after being swept up in a Lap 190 crash. Although he has shown the power to run near the front this year, he has four consecutive finishes of 13th or worse.

Alex Bowman

  • Points position: 20th
  • Best seasonal finish: 3rd (Las Vegas I)
  • Past at COTA: Two straight top 10s

Bowman’s four-race run of consistent excellence (finishes of fifth, eighth, third and ninth) ended at Atlanta as he came home 14th and failed to lead a lap. At COTA, he is one of only four drivers with top-10 finishes in both races.

William Byron

  • Points position: 28th
  • Best seasonal finish: 1st (Las Vegas I, Phoenix I)
  • Past at COTA: 11th and 12th in two starts

Involvement in an accident at Atlanta ended Byron’s two-race winning streak. He’ll be looking to lead a lap at COTA for the first time.
