Joe Gibbs Racing executive says team was off on measurements that caused Denny Hamlin’s penalties (video)

5 Comments

Jimmy Makar, senior vice president of racing operations at Joe Gibbs Racing, said “circumstances that are out of your control” from pushing the limits of the rules contributed to both of Denny Hamlin‘s winning cars at Darlington failing inspection, resulting in encumbered finishes and suspended crew chiefs.

Mike Wheeler, crew chief for Hamlin’s No. 11 Toyota in the Cup Series, and his Xfinity crew chief Eric Phillips, both were suspended two races because of an L1 penalty for violating section 20.14.2 (rear suspension) of the NASCAR Rule Book.

On SiriusXM NASCAR Radio’s “Tradin’ Paint,” Makar attributed the violations in tolerances to the wear-and-tear of Darlington Raceway and the way NASCAR inspects cars at its R&D Center compared with immediately after a race.

“We’ve been back to the tech center with the race cars multiple times this year and been checked for these same rear suspension measurements they’re doing that we were found to be out of tolerance on (after Darlington),” Makar said, indicating the cars previously had passed those inspections.

“This measurement that they’re using back at the tech center is new this year the way they’re doing it. … They check it at the racetrack a little differently. And we were fine in prerace and postrace on the measurements they take there.

“The problem became when they came back to the tech center, and they measured it in a different way is where we got into the discrepancy on the amount of tolerance.”

Makar said the distinction is important because “it’s a little different than just having an illegal part or something like that that just blatantly you try to get by with. That’s kind of black and white, and nobody wants to get involved in that kind of mess. This kind of situation is more of a tolerance, a measurement that they measure at the racetrack.”

A team’s goal, Makar said, is to find the limits of those measurements. “You know you want to take advantage of every opportunity you can to make your race car faster and give your driver all the advantages they can have,” he said. “There is a line there you don’t want to cross, but as long as you’re dancing on that line, you have circumstances that are out of your control sometimes that cause a problem.”

After the Southern 500, NASCAR took the cars of Hamlin, second-place finisher Kyle Busch and Austin Dillon back to the R&D Center for a more thorough inspection. The penalties were announced Wednesday.

Cars run close to the wall at Darlington, and Makar said the team probably hadn’t built in enough of a cushion for parts that bent because of the frequent contact.

“You hit the wall several times during the course of the race with the right rear,” Makar said. “Things get bent. Things move. I think all those things added up to this couple thousandths of tolerance that we were out. It’s not an excuse, but as we look back at it, we did leave ourselves enough room for those things to happen. … Even if you were going to be a little bit inside the (tolerances), you still don’t know if hitting (the) wall one time is one time too many.”

JGR already has announced it won’t appeal the penalties, which means Wheeler will miss this weekend’s regular-season finale at Richmond Raceway and the postseason opener next week at Chicagoland Speedway.

Makar said NASCAR ideally should conclude the inspection process immediately after the race.

“Within an hour or two or a couple of hours after the end of the race, so we know there’s been a problem or not,” Makar said. “That’s not in our hands. NASCAR has got to figure out how to do that. It’s not an easy thing.”

Though JGR accepted the penalties, Makar said a more widespread inspection could have yielded more cars that were out of bounds.

“This is my opinion and my opinion only, but I think you could’ve taken every car that finished that race this weekend and found most of them have a little bit of the same problem,” Makar said. “It’s just what it is. But that’s not the way they inspect after a race.”

Dr. Diandra: Strategies in making Clash picks

0 Comments

Crew chiefs must develop their approach to today’s Busch Light Clash at the Coliseum using only last year’s data, plus this year’s practice and qualifying.

Fans wagering (for fun and/or profit) must contend with the same lack of data as they make their Clash picks.

The shortest regular-season track is a half mile. A quarter-mile track is a different beast, even with a year’s worth of Next Gen experience.

“Last year everything was brand-new – the track, the format and the car,” Alan Gustafson, crew chief for Chase Elliott, said in a team release. “We’ll have a little bit better of an idea of what we’re going for this time around, but the track is so unique that even with going there last year, we’re still learning.”

As are the fans.

There are a few changes to keep in mind as you make your Clash picks.

NASCAR increased the field from 23 cars to 27. With 36 drivers entered, only nine will miss the Clash. Even without points on the line, no one wants to head home before the main event’s green flag.

Last year, equipment failures caused four out of five DNFs in the main race. Expect fewer mechanical issues this year.

But perhaps more aggression.

Don’t pay too much attention to practice

Last year’s practice times showed no correlation with Clash performance. Eventual winner Joey Logano finished practice last year with the 26th fastest lap — also known as the 11th-slowest lap. But he qualified fourth.

This year, despite losing about 40 hp to mufflers, Martin Truex Jr. set a fastest lap of 13.361 seconds. Truex’s lap beats last year’s best practice lap time of 13.455 seconds, set by Chase Elliott.

Although only seven-tenths of a second separate the fastest practice lap and the slowest, the change is far from linear.

A graph showing practice times for the Busch Light Clash field

  • The top 11 drivers are separated by just 0.048 seconds out of a 13- to 14-second lap
  • Brad Keselowski, who didn’t make the race last year, had the third slowest practice time.
  • Tyler Reddick ran the most total practice laps with 117. He was followed by Kevin Harvick (116), and Noah Gragson and Ricky Stenhouse Jr., both of whom made 115 laps.
  • Most drivers ran their best times in their first or second session. Austin Dillon, however, ran his best time on lap 109 of 112.
  • The top three in practice also had the three best 10-lap averages.

Qualifying is the key to good Clash picks

Last year, qualifying position correlated well with driver finish in the Clash. If your driver qualified on the front two rows for his heat race, last year’s results suggest that the only thing keeping him from making tonight’s Clash is an accident or mechanical failure.

That’s bad news for Ty Gibbs, who wasn’t allowed to qualify and will start in the back of the field. It’s also a negative for Ryan Blaney, who posted a 40-second lap, however, Blaney has a shot at the provisional and Gibbs doesn’t.

The heat races are only 25 laps, which doesn’t leave much time for passing. Heat race starting position is highly correlated to heat race finishing position.

  • Last year, the pole-sitter for each of the four heat races held the lead for the entire race.
  • Of the 12 drivers starting in the top three for each heat race, nine drivers — 75% — finished in the top three.
  • Only the top-four finishers of each heat race advanced last year. This year, the top five move on. Last year, 16 of the 25 drivers (64%) starting in positions one through five finished in the top five of their heat races.
  • No driver who started a heat race from ninth finished better than sixth. That’s not encouraging news for Blaney and Gibbs, among others.

That means Justin Haley, Kyle Busch, Christopher Bell and William Byron are pretty much guaranteed locks for a good starting spot in the Clash.

The 20 drivers who qualified in the top five for their heat race have a very high probability of making it through to the main — and of finishing well there.

As was the case last year, practice showed little correlation with qualifying. Martin Truex Jr. qualified 22nd despite posting the best practice time.

The Last Chance Qualifiers

Three drivers from each of the two last chance qualifiers fill out the final rows of the Clash starting grid. Last year, drivers were more aggressive in these 50-lap races than the first four heats.

Again, the closer to the front a driver starts, the better his chance of making the race. Last year, both pole-sitters finished in the top three and advanced.

The last chance qualifiers are long enough for a driver starting in the rear to make it to the front. Last year, Ty Dillon came from 10th place to win the second race. He was subsequently disqualified for jumping the final restart and Harrison Burton, who had started seventh, advanced. If you’re looking for long-shot Clash picks, don’t count the back of the field entirely out.

The Big Show

Last year, the 150-lap main had five lead changes and five cautions.

  • Of last year’s four heat-race winners, two finished in positions one and two, while the other two didn’t finish the race.
  • Of the six drivers who advanced from the last chance qualifiers, none finished higher than A.J. Allmendinger in ninth.
  • Allmendinger tied with Erik Jones for most spots gained. Jones started 16th and finished fourth.
  • Excluding drivers who failed to finish the race, Danial Suárez had the biggest position loss, starting fifth and finishing 14th.

If you want to avoid the frontrunners, you might want to keep an eye on Aric Almirola, who qualified fifth, and had the seventh best 10-lap average run during practice. Austin Dillon didn’t put together a strong 10-lap run, but his team found something in the last minutes of practice that allowed him to go from finishing practice in 22nd to qualifying sixth.

And although Bubba Wallace qualified 16th, he ranked first in runs of 10, 15, 20, 25 and 30 laps. He was second in five-lap speed.

Good luck with your Clash picks!

LOS ANGELES — Justin Haley, Kyle Busch, Christopher Bell and William Byron will start on the pole for their heat races Sunday at the Los Angeles Memorial Coliseum. 

There will be nine cars in each of the four heat races. Here’s a look at each of the those heat races.

Clash heat race starting lineups

Heat 1

This heat has four drivers who did not make last year’s Clash: Alex Bowman, Aric Almirola, Chris Buescher and Ty Dillon. Almirola starts second, Bowman third, Buescher eighth and Dillon ninth. This heat also has defending Clash winner and reigning Cup champion Joey Logano, who starts fifth.

Heat 2

Richard Childress Racing teammates Busch and Austin Dillon start 1-2. This race has five former champions: Busch, Kyle Larson (starting third), Kevin Harvick (fourth), Martin Truex Jr. (fifth) and Chase Elliott (eighth).

Heat 3

Toyota drivers will start first (Bell), second (Denny Hamlin) and fifth (Tyler Reddick). Ryan Blaney starts last in this heat after his fastest qualifying lap was disallowed Saturday.

Heat 4 

Byron will be joined on the front row by AJ Allmendinger in this heat. The second row will have Ross Chastain and Bubba Wallace.

The top five in each heat advances to Sunday night’s Clash. Those not advancing go to one of two last chance qualifying races. The top three in each of those races advances to the Clash. The 27 and final spot in the Clash is reserved for the driver highest in points who has yet to make the field.

Justin Haley tops field in Clash qualifying

LOS ANGELES — Justin Haley posted the fastest lap in Saturday’s qualifying for the Busch Light Clash at the Los Angeles Memorial Coliseum.

Haley will start the first of four heats on the pole after a lap of 67.099 mph (13.413 seconds). The four heat races will be held Sunday afternoon, followed by two last chance qualifying races and then the Busch Clash on Sunday night.

Clash qualifying results

“I feel pretty confident about where we are,” Haley said. “I’m not sure why we’re so good here.”

The top four qualifiers will start on the pole for their heat race.

Kyle Busch, who was second on the speed chart with a lap of 66.406 mph, will start on the pole for the second heat. That comes in his first race with Richard Childress Racing after having spent the past 15 seasons at Joe Gibbs Racing.

Christopher Bell, third on the speed chart with a lap of 66.328 mph, will start on the pole for the third heat. William Byron, fourth in qualifying with a lap of 66.196 mph, will start on the pole in the fourth heat race.

The pole-sitters for each of the four heat races last year all won their heat. That included Haley, who was third fastest in qualifying last year and won the third heat from the pole.

Ty Gibbs was not allowed to qualify because of unapproved adjustments his team made while making repairs to his car after the door foam caught fire during practice. NASCAR deemed that the Joe Gibbs Racing team made adjustments to the car not directly related to the damage.

Ryan Blaney‘s fastest qualifying lap was disallowed after he stopped the car in Turn 4 and turned it around and to go back to the backstretch and build speed for his final lap. NASCAR disallowed the time from that final lap for the maneuver.

Section 7.8.F of the Cup Rule Book states: “Unless otherwise determined by the Series Managing Director, drivers who encounter a problem during Qualifying will not be permitted to travel counter Race direction.”

The top five finishers in each of the four 25-lap heat races advance to the Clash. The top three in the two 50-lap last chance races move on to the Clash. The final spot in the 27-car field is reserved for the driver highest in points not yet in the field.
