BRISTOL, Tenn. — Two more drivers are headed to the checkered flag of their NASCAR careers and the laps are winding down for a golden age of racing.

Kasey Kahne and Elliott Sadler both said this will be their final season of racing full time as they become the latest two veterans to find they no longer want to be part of the traveling circus. Dale Earnhardt Jr., Jeff Gordon, Tony Stewart, Carl Edwards, Greg Biffle and Danica Patrick have already given up their seats in stock cars to spend more time doing, well, everything they’ve missed in life.

Kahne and Sadler, who have a combined 1,589 starts at the NASCAR national level, want to spend more time with their kids and not spend 38 weekends a year at a track. They are part of a group of drivers that broke into NASCAR when the sport went mainstream and money poured in from corporations all over the world.

If a driver could get a seat in the Cup Series and parlay it into a strong sponsorship deal, they virtually guaranteed themselves a lengthy career that earned them massive paydays, private planes, mansions, motorhomes and long-term financial security.

“I got to basically make a run and live in an awesome time in NASCAR,” said Kahne, who debuted in 2002 and has logged 15 years in the Cup Series. He has 18 career victories and, prior to 2016 when NASCAR stopped publishing winnings, Kahne had earned $71.4 million.

Kahne is 29th in the Cup standings with one top-10 finish all season, but is fresh off watching sprint car driver Brad Sweet drive a Kasey Kahne Racing entry to victory last weekend in the prestigious Knoxville (Iowa) Nationals. Five days after that win, Kahne announced he wants to spend more time with his young son and his sprint car team.

“I need to just back off a little bit,” Kahne said.

Sadler cited his two young children and their packed schedules as one of the reasons he’ll stop running full-time in the Xfinity Series at the end of the season. He is currently second in the standings.
