Gerrit has raced Go-karts since he was seven years old. He started out in an Arrive and Drive program at Goodwood Kartways, which would end up being his home track. In 2008, Gerrit moved up to racing his own kart with the help of his dad. He finished 2nd overall in the track points against many kids that were older than him. In 2009, Gerrit came up strong winning several races and the track championship. In 2010, Gerrit moved up to the Rotax Minimax division, finishing fourth overall. But Gerrit came back the next year again winning the championship and several feature wins. In 2012 and 2013, Gerrit ran Rotax Jr, an international promoted class,(Picture above). He finished 3rd overall and only ran a partial schedule in 2013. In the 2014 season, cars at Sunset Speedway would be the challenge of the year, and Gerrit would rise to finish 5th overall in the standings.
Derrick has raced the longest out of the Tiemersma family. He started around the age of 20 and is still racing the short tracks today. Derrick started out racing enduros, with his brother, Steve, in the late '80s. He and Steve both ran Thundar Car when it was first a new divsion, taking charge over the fields of cars. While Steve still ran Thundar Car, in 1992, Derrick moved up to the Challenger division, taking the Rookie of the Year Award. The next year he followed up with the championship at Sunset Speedway. Like in '92, Derrick moved up a division, into Late Model. He won the Rookie of the Year Award again, but could not swipe the championship in his second year of driving Late Model. He ended up finishing in a close 2nd place overall. In 1996, Derrick ran a limited schedule, as he was thinking about running in the Cascar Super Series next year,(Nascar Canadian Tire Series). In 1997, he did move up to Cascar, running only 4 races with three top tens. In 1998, he ran a full season, winning the Rookie of the Year award. The next year he ran as best as he could but only came to an 11th place finish overall. In 2000, Derrick ran a limited schedule because of the cost, but also because there was a young baby at home. Over the course of 6 years in the Alstar Super Series, Derrick didn't win any championships, but came up with two 2nd's, three 5th's, and an 8th place overall finish. 2007 was a great year for Derrick, as he won the Don Biederman Memorial, Rookie of the Year, and the 2007 Oscaar Super Late model Championship. From 2008-2010, Derrick competed hard still with two 2nd place overall finishes and one 5th place overall finish. Due to personal reasons, Derrick had to take a year off in 2011, but came back hard in 2012. He finished 3rd overall after taking a year off. He finished the 2013 season with a top five finish overall.
Steve would be considered a veteran at Sunset Speedway. When he began his racing career, it started out with enduros, which sometimes had over 100 cars starting a feature. Steve started At Sunset in the thundar Car division. Over the years of 1991-1996, Steve had won a Thunder Car Championship as well as two Challenger Championships. When Steve moved up to Late Model in 1997, he finished 2nd in points at sunset. From 1998-2000, Steve hit the peak of his career. With two 2nd overall finshes and a Championship in the Alstar series, everyone was chasing him. He then finished 5th overall for three straight years after that. When the Alstar series had closed in, Steve raced a little less, but still competed. In 2003, he won the Autumn Clours Classic and finished 3rd in that race in 2004. '04 would be Steve's last year of racing, because of Gerrit, who was going to start racing Go-karts.
