NASCAR officials will return to Michigan International Speedway on Tuesday, Oct. 20 to test a low downforce package similar to what was used in competition last month at Darlington Raceway . Drivers scheduled to take part in the test are defending NASCAR XFINITY Series champion Chase Elliott in the Hendrick Motorsports No. 25 Chevrolet, current XFINITY Series points leader Chris Buescher ( Roush Fenway Racing No. 17 Ford) and Chase for the NASCAR Sprint Cup contender Denny Hamlin ( Joe Gibbs Racing No. 11 Toyota). According to information provided to the teams on Wednesday, the test is to verify max and corner speeds with three different grip levels of tires. The schedule calls for individual 10- and 25-lap runs in the morning and afternoon sessions. The lower downforce package debuted at Kentucky Speedway this season before also being put into play at Darlington, where it featured a 3.5-inch spoiler, 25-inch splitter extension panel (radiator pan) and 6.63-inch by 25-inch splitter. The only change for the MIS test will be an increase in the splitter extension panel to 33 inches. Drivers and teams were pleased with the initial results of the package, particularly at Darlington where Goodyear was able to provide a specific tire based on data gained from testing there prior to the race. The MIS test will take place approximately two months after the Sprint Cup Series competed at the 2-mile facility with a high-drag aerodynamic configuration. A high-drag package was also used at Indianapolis Motor Speedway . JGR driver Matt Kenseth called the high-drag package "terrible." "You just can't pass," he said after finishing seventh in the Jeff Kyle 400 at the Brickyard. "Yeah, you can run up on the straightaway a little bit, but you can't run though the corner with anything." A month later, after his driver dominated at Michigan with the same rules package, Kenseth's crew chief Jason Ratcliff said "at the end of the straightaway (cars could) gain on others two or three car-lengths. But they just couldn't do much once they got there and they got down in the corner, they were kind of helpless." The high-drag rules included a 9-inch spoiler with a 1-inch wicker bill, a rear fascia extension panel (similar to those used for superspeedway events at Daytona and Talladega), a 2-inch leading edge on the splitter and a 43-inch splitter extension panel. "We know that high drag package is awful," four-time premier series champion Jeff Gordon said following the Darlington race. "We know that this (lower downforce) is definitely in the right direction. … I think when you look at the less horsepower we had coming in this year it's the package that should have been with this car that we have now. You can't take that kind of power away and not do something significant to the downforce as well." Homestead Test Slated for December NASCAR and Goodyear officials have added a post-season test scheduled for Dec. 14-15 at Homestead-Miami Speedway to continue preparations for the 2016 rules package. Organizations scheduled to participate in the test are Stewart-Haas Racing (Chevrolet), Hendrick Motorsports (Chevrolet), Richard Petty Motorsports (Ford) and Furniture Row Racing (Toyota). It is expected to be the first on-track testing for Furniture Row and driver Martin Truex Jr . with a Toyota entry. The Denver-based team is making the switch from Chevrolet to Toyota for '16. Because of the change, SHR was added to the test to replace Furniture Row for Chevrolet. "I think '16, we're not really even thinking about right now," Truex said earlier this week. "We know what we're doing next year, we'll worry about that after (the final race at) Homestead. "I think everybody in the Chase is probably in the same position -- you're worried about today and tomorrow and this coming weekend. No further ahead. Once you set your plans, it's real easy." Lineup Change for Atlanta Test The Toyota teams of Michael Waltrip Racing and BK Racing have declined to take part in the Goodyear tire test slated for Oct. 27-28 at Atlanta Motor Speedway . Joe Gibbs Racing has been added to the lineup to represent Toyota teams at the 1.54-mile track. MWR will not field a full-time Sprint Cup Series team next season. The two-day program is a confirmation test for Goodyear; an open team test is scheduled for Oct. 29 following the completion of the tire test. CMS Tire Info Sprint Cup and XFINITY Series teams will be running the same tire codes this weekend at Charlotte, according to Goodyear officials, and is unchanged from what was provided for the 1.5 mile track's May races. The left-side tire code has been used at CMS since 2012; the right side, which features a multi-zone tread, was used there for the first time in May.
RELATED: Complete race lineup CONCORD, N.C. -- For a driver who keeps insisting that qualifying isn’t his strong suit, Matt Kenseth continues to excel on NASCAR Sprint Cup Series Coors Light Pole days. Touring the 1.5-mile Charlotte Motor Speedway in a blistering 27.759 seconds (194.532 mph) on Thursday night, the driver of the No. 20 Joe Gibbs Racing Toyota earned the top starting spot for Saturday night’s Bank of America 500 (7 p.m. ET, NBC, PRN, SiriusXM), the first race in the Contender Round of the Chase for the NASCAR Sprint Cup . Kenseth was .198 seconds quicker than JGR teammate Kyle Busch (193.154 mph), who put the No. 18 Toyota on the outside of the front row. Busch's car is sporting a pink paint scheme this weekend to bring attention to the work of his foundation in fighting breast cancer. The Coors Light Pole Award was Kenseth's fourth this year -- a personal best for a single season -- his second at Charlotte (and second consecutive) and the 17th of his career. Kenseth didn't have a perfect lap, but as he crossed the start/finish to complete the circuit, he knew he had a shot at the pole. "It was a heck of a lap," Kenseth said. "I knew I had a lot of speed. I kind of changed it up in (Turns) 1 and 2 a little bit, and I just got a little tight in the middle of (Turns) 3 and 4. I knew the car was fast. Our Dollar General Camry has been fast all day, and it was a lot of fun to drive." Kenseth gave the car and crew chief Jason Ratcliff's setup much of the credit for his pole-winning effort. "I knew it was going to be real fast," Kenseth said. "I didn't know we were going to sit on the pole by any means, but it had the feel and everything that I wanted. It's funny, this place, if you can get it to drive just like you want, you can really perform well here, but it's so hard to get that feel ... "But today he (Ratcliff) got it to drive that way. I was going to have to mess it up to not get it, as good as he had it there." Joey Logano (193.023 mph) qualified third, followed by Greg Biffle (192.947 mph) and Denny Hamlin (192.912 mph). With Carl Edwards claiming the eighth starting spot, JGR put all four of its drivers, all of whom are Chase contenders, in the top eight. All told, Chase drivers grabbed nine of the top 12 positions on the grid, with Biffle, Jimmie Johnson (seventh) and Aric Almirola (ninth) the only non-Chase drivers able to advance to the final round of knockout qualifying. Busch, who fought his way back into the Chase with a second-place finish last Sunday at Dover, was pleased with his effort in time trials. "I don't know -- Matt Kenseth , he was better than me, that's for sure," Busch said. "He got more out of it than me, but our pink M&M's Camry is awesome. We were able to post some good speed there. I'm real happy with it ... and I'm looking forward to the race on Saturday night." All 12 Chase contenders advanced through the first round, but Brad Keselowski (13th), Martin Truex Jr . (15th) and Jeff Gordon (22nd) weren't fast enough to make the final elimination session, which is restricted to the top 12. Keselowski ran an identical lap to 12th-place Carl Edwards but lost the final spot in the third round on an owner points tiebreaker. Josh Wise and Timmy Hill failed to make the 43-car field. The Sprint Cup Series is back on track on Friday for practice at 3:30 p.m. ET (NBCSN/Live Extra).

Race fans who have already purchased DAYTONA 500 tickets can add Sprint FANZONE/Pre-Race access and VIP area access for $110. All VIP ticket packages will be available beginning at 9 a.m. on Sept. 28. For Kelley, performing at the "World Center of Racing" will be a homecoming having grown up in the neighboring city of Ormond Beach. Kelley attended Seabreeze High School and Daytona State College and his father, Ed Kelley, has been the mayor of Ormond Beach since 2010. "It's a dream come true to play in the city where I was born, went to high school in and now have the honor of being a part of one of my family's favorite sporting events, the DAYTONA 500," Kelley said. "Performing at the 500 feels full circle to me as I grew up working the 500 as a fundraiser for our baseball team and was in awe then and still am." "We're extremely thankful for the opportunity to be part of such a huge day for NASCAR and our fans. We can't wait to bring the biggest party the DAYTONA 500 has ever seen," Hubbard said. Florida Georgia Line fueled with three scorching consecutive #1 hits -- GOLD-certified "Sippin’ On Fire" and "Sun Daze" and 2X PLATINUM-certified "Dirt" -- and the recently-released title track, Florida Georgia Line radiates with the GOLD-certified sophomore album ANYTHING GOES (Republic Nashville). Their latest album soared to a #1 debut on the all-genre Billboard 200 and Billboard Top Country Albums charts with music critics and fans alike embracing the superstar duo's fresh sound.

Taking their undeniable songwriting skills to the next level and discovering new talent, FGL recently formed publishing company Tree Vibez Music, whose moniker was aptly inspired by Kelley's custom treetop recording studio built by Pete Nelson for the hit show Treehouse Masters. In addition to collaborating across genres with sensations like Nelly and Jason Derulo, FGL has racked up a plethora industry awards, closing out an epic 2014 topping four of Billboard's year-end charts and leading Forbes "30 Under 30" list. The accolades continue to pour in: FGL brought home two ACM Awards -- their second consecutive Vocal Duo of the Year title and Vocal Event of the Year ("This Is How We Roll" featuring Luke Bryan) -- a CMT Music Award for Duo Video of the Year ("Dirt") and tallied four Billboard Music Awards nominations. They are currently on tour through October 17.

RELATED: Full results from New Hampshire " Updated standings MORE: See the new Chase Grid LOUDON, N.H. -- Kevin Harvick clarified his championship status on Sunday -- but not the way he had planned. After dominating the Sylvania 300 at New Hampshire Motor Speedway for most of the afternoon, Harvick ran out of fuel while leading on Lap 298 of 300, handing the top spot and the victory to Matt Kenseth , who joined teammate Denny Hamlin as an automatic qualifier for the Contender Round of the Chase for the NASCAR Sprint Cup . Despite leading 216 laps on Sunday, Harvick, the defending series champion, heads to next Sunday's Chase race at Dover almost certainly needing a victory at a track where he has never won in order to escape the Challenger Round of the Chase and keep his title hopes alive. Kenseth, who came to pit road for fuel and tires on Lap 239, triumphed for the fifth time this season (tops in the NASCAR Sprint Cup Series), for the second time at the Magic Mile and for the 36th time in his career. He finished 8.941 seconds ahead of Hamlin, who nursed his car to a runner-up finish despite a late-race issue with the right front wheel. "It feels great to win here -- a lot of great race fans here at New Hampshire," Kenseth said. "We had a great car today -- Kevin definitely had the field covered and (Kenseth's crew chief) Jason (Ratcliff) did a great job on pit strategy there, and those new tires paid off better than we thought to get up through the field. "And I was able to keep the pressure on enough and he came up a little short." The victory was the 13th of the season for Joe Gibbs Racing , which has won 10 of the last 13 Sprint Cup events. Joey Logano ran third, followed by Greg Biffle , Carl Edwards , Jimmie Johnson , Jeff Gordon and Martin Truex Jr . The only non-Chase driver of that group, Biffle posted his third top-five result of the season. Dale Earnhardt Jr . had a consistent top-10 car all afternoon, until he, too, ran short of fuel with two laps left and finished 25th. Earnhardt goes to Dover with no margin for error. He’s 12th in the standings, the final position that will survive elimination next Sunday, and just one point ahead of both Kyle Busch and Paul Menard . Busch blew a right front tire on Sunday, pounded the Turn 3 wall on Lap 159 and was credited with a 37th-place finish. Harvick, who finished 21st and declined comment after the race, came to pit road for the last time on Lap 212 and couldn't squeeze the last 88 laps at the 1.058-mile track out of his fuel cell. Restarting third on Lap 243 after the ninth and final caution (for Justin Allgaier 's wreck in Turn 3), Harvick passed Biffle for the lead on Lap 252. Twenty laps later, Kenseth got past Hamlin for second and tried to pressure Harvick, who left Loudon in 15th place, 23 points behind Earnhardt in 12th. " Jason kept saying he (Harvick) was low on fuel, but you never know unless they really run out," Kenseth said. "I was trying to run hard, but I was trying to save a little bit. I got racing Denny pretty hard, and I wanted to save the tires a little bit, but I also know I needed to get by him to pressure the 4 (Harvick). "That was as hard as I could run. I was planning on running up there and trying to pass him. I just couldn't get there. Kind of resigned to finish second with about four or five (laps) to go there. I couldn't get much closer, and he ran out with a couple to go." Second to Kenseth in the standings, six points out of the Chase lead, Hamlin also acknowledged JGR's good fortune on Sunday. "Really, I don't feel like we were dominant today by any means," Hamlin said. "Yeah, our cars finished 1-2, but I'm not sure that we had 1-2 cars most of the day. "So I think we've been very fortunate with some strategies and things that we've played that's worked out in our favor. You've got to just keep working. That's the only way you can stay on top is to not rest."
Martin Truex Jr. who was originally starting in 9th position is now forced to start at the back of the field after having to make adjustments before the race.

RELATED: Answers on multiple packages " Darlington's throwback gallery Perhaps somewhat overshadowed by all the talk about Darlington Raceway 's "throwback" platform this weekend is the return of NASCAR's low downforce package, incorporating aerodynamic changes first unveiled at Kentucky Speedway earlier this year. Three significant changes have been incorporated into the Sprint Cup Series package for Sunday's Bojangles' Southern 500 (7 p.m. ET, NBC/Live Extra, MRN, SiriusXM NASCAR) that differs from the package used in the Quaker State 400 at Kentucky in July. The Darlington spoiler will be 3-1/2 inches (instead of 3 inches) and the splitter will feature a 1/4-inch leading edge. Also, the tires to be used at Darlington were built specifically for this particular low downforce package. The build was determined after a one-day test in July with drivers Matt Kenseth ( Joe Gibbs Racing ), Brad Keselowski ( Team Penske ) and Tony Stewart ( Stewart-Haas Racing ). There is no change in the size of the splitter extension panel, which was set at 25 inches for the Kentucky event. Driver feedback, for the most part, was positive following Kentucky. But Jason Ratcliff, crew chief for Kenseth, noted that differences in the two tracks and other considerations would have an impact this weekend at Darlington. "It's going to be a lot different … because we haven't run at Darlington at this time of year in a while," he said. "… Darlington is unique anyway -- you run right around the fence, which makes it difficult to pass, but I thought the aero package was good and we were able to work on the car and find some speed and nothing negative with it." Fellow Joe Gibbs Racing driver Carl Edwards said he's looking forward to putting the low downforce package back on the track. "The way we've been running lately and the way this package drove at Kentucky, I mean to me Darlington is going to be like Christmas in September. I'm pumped," he said. So About Those Tires The tire combination selected by Goodyear will feature the same left-side tire code used at Indianapolis Motor Speedway this year with a right-side tire code that was run at Kentucky. "We had a very minimal change in grip at Kentucky from what we raced there in 2014," Greg Stucker, Director of Race Tire Sales for Goodyear, told SiriusXM NASCAR on Wednesday. "Just a little bit more grip on the left-side tire, and the results of that particular event I think were very, very positive. "I think the low-downforce package showed a lot of potential. I think a lot of people walked out of there thinking that was a really nice package. It certainly reduced grip, put a lot of control back into the drivers' hands. Did a lot of things that I think people were looking for." Stucker said a "considerable amount of grip" has been added to the Darlington tires, with hopefully will offset some of the aerodynamic grip lost with the aero changes on the cars. "The reduction in downforce going from the standard 2015 (package) to the low-downforce package increased lap times by about three-quarters of a second, 7/10ths to 8/10ths, something like that," he said. "That much slower. When we put the grippier setup on, it gave us about that same 7/10ths to 8/10ths back." A December test at Charlotte Motor Speedway in 2014 actually provided some of the initial data for the low downforce tire build. "We went back there again in March of this year to confirm that tire package for a low-downforce setup that at the time was thought to be run in the (Sprint) All-Star Race," Stucker said. "So we had a lot of work done in a similar configuration. Historically Darlington and Charlotte are similar. We run the same right-side tire there, slightly different left. But it gave us a real good starting point for where to go back to Darlington so we did that." Riding a Blue Streak The teams and track officials aren't the only ones on board with this year's "throwback" theme for the Bojangles' Southern 500 . Even Goodyear is going retro, returning to a logo design used in the 1970s. At that time, the logos and markings on each tire were hand-painted -- that won't be the case this weekend -- "but they'll definitely have the looks of what we ran back in the '70s," Stucker said. "We had not yet gone to Eagle on our race tires. They were still called Blue Streak Specials." The yellow Goodyear lettering seen on today's Goodyear Eagle tires came into use in 1992.
