For over 20 years, Superkarts! USA has been part of the sport of karting in the United States, and the organization formed its own Hall of Fame in 2016 to begin honoring those who have played key roles in its history. This year, SKUSA is proud to announce that the late Fausto Vitello will be inducted into the Hall of Fame to honor his tremendous contributions to not only the organization, but to karting as a whole. Vitello, who passed away from a heart attack in 2006, was the founder of Trackmagic Racing Karts, the San Francisco-based chassis manufacturer that pushed the envelope for American kart builders through 100% commitment to innovation and its culture. Vitello will be joined in the Hall of Fame by SKUSA’s own Stan Bryniarski, who has been a cornerstone workhorse and crusader of the organization for 20 years as a Regional Director, Race Director and now, the current National Director of Operations.

At the end of September, the California ProKart Challenge closed out the 2018 championship chase with the 10th running of the Streets of Lancaster Grand Prix.

Back in February, competitors began a six-event journey throughout California to compete against some of the best racers on the continent around six unique and challenging circuits. Now the 12 title winners of 2018, along with the rest of the competitors and supporters who raced with the California PKC program, are invited to the Championship Awards Banquet scheduled for the evening of October 27 in Anaheim, California.

Wednesday, 10 October 2018 13:08

After months of development and fine tuning, IAME USA West today confirmed the initial shipment of the long awaited IAME SSE. The first units are expected to arrive in the United States as early as next week. Orders will begin immediate fulfillment in the order they were received, with boxes leaving the IAME USA West headquarters as quickly as they come in.

“It’s been a long time coming,” remarked IAME USA West and SKUSA principal Tom Kutscher. “If I had a dollar for every time someone asked me when the new engine would be here, I’d be a wealthy man. The demand for this thing is unreal and I couldn’t be more excited to finally have it here.”

Superkarts! USA completed its ninth season of the SKUSA Pro Tour this August. The three-event, six-round championship program traveled from the southeast to the southwest before finishing in the midwest to decide the nine series champions in the IAME and Honda categories. Those drivers who were able to achieve podium finishes throughout the season, earn enough points to be crowned champion or finish the season among the top-three were all able to grab a portion of the near $100,000 prize package for the 2018-2019 seasons.

Beginning in March, the WinterNationals kicked off the 2018 season at NOLA Motorsports Park in New Orleans. The Phoenix Kart Racing Association then welcomed the SKUSA Pro Tour for the SpringNationals once again in May. The 2018 championship chases were then decided at the New Castle Motorsports Park for the SummerNationals in Indiana in August.
