WATERLOO, Iowa (September 11, 2025) – The racing community in Iowa and across the IMCA (International Motor Contest Association) world is mourning the passing of Greg Kastli, a longtime supporter, champion, and respected competitor, who died on Wednesday, September 10, at the age of 72.

For decades, Kastli was a familiar and beloved name in the pits, on the track, and in the hearts of fans. Known for his grit behind the wheel and his humble, approachable personality, he leaves behind a legacy rich in victories, championships, and friendships.

A Storied Career in IMCA Racing

Greg Kastli’s journey through racing was defined by both excellence and consistency. He was best known for piloting an IMCA Late Model, where his name became synonymous with success across the Midwest. Over the course of his career, he recorded 40 sanctioned Late Model feature wins, placing him among the most accomplished drivers in IMCA history.

Kastli’s competitive spirit and skill were evident early on. In 1989, he reached one of the sport’s greatest milestones, becoming the IMCA Super Nationals Late Model Champion. That victory not only cemented his status as a top-tier competitor but also etched his name permanently into IMCA’s proud history.

His dominance extended across multiple decades, highlighted by track championships at some of Iowa’s most storied speedways. He claimed the Fayette County Raceway title in 1994 and went on to collect four Late Model championships at Independence Motor Speedway, in 1994, 2001, 2002, and 2003. His consistency at Independence made him a fan favorite and a driver to beat, year after year. By the close of the 2025 season, he was tied for third place on the all-time Late Model wins list at the track—an achievement that speaks volumes about his longevity and competitive drive.

Success Across Divisions
Though best known for his Late Model triumphs, Kastli also made his mark in the Modified division. He secured 18 IMCA Modified feature wins and captured the 1986 Modified track titles at both Independence Motor Speedway and the Dubuque Fairgrounds Speedway. His ability to compete—and win—in multiple classes reflected his versatility and talent behind the wheel.

Whether in a Late Model or a Modified, Kastli always carried himself with the same determination and quiet confidence, earning respect not only from fans but from fellow drivers as well.

Recognition and Hall of Fame Induction
Greg Kastli’s contributions to the sport extended beyond checkered flags. He was deeply committed to the IMCA community, supporting the organization and local tracks throughout his life. His dedication did not go unnoticed.

In a rare exception to tradition, officials at Independence Motor Speedway waived the requirement that drivers be retired for five years before induction into the track’s Hall of Fame. Earlier this summer, Kastli was enshrined as one of the most popular inductees in recent memory. For many, it was a fitting honor for a driver who had given so much to the track and the sport as a whole. The standing ovation he received that day spoke volumes about the admiration he had earned over decades of competition.

More Than Just a Racer
Beyond the statistics, Greg Kastli was remembered as a mentor, friend, and family man. His approachable nature and willingness to help others made him a fixture in the racing community. He inspired younger drivers to chase their dreams and reminded veterans of the joy that comes from competing in the sport they love.

Fans recall him not just for his victories, but for the way he carried himself—with integrity, humility, and a true love for racing. He was as proud of the friendships forged in the pits as he was of the trophies earned on the track.

A Lasting Legacy
With his passing, the IMCA family has lost not only a champion but also a cornerstone of its community. His accomplishments on the track will continue to inspire future generations of racers, while his character off the track will remain a guiding example of what it means to be both a competitor and a friend.

As services for Greg Kastli are pending, tributes continue to pour in from across the racing world. His life and career will be celebrated not only by his family and close friends but by the countless fans and fellow drivers whose lives he touched.

In the words of many who raced alongside him: Greg Kastli was more than a driver—he was a true racer’s racer, a champion in every sense of the word, and a man whose legacy will endure far beyond the finish line.
