Fond Farewell, COTA season finale race recap and video
Saying Farewell To Our Friend and Leader Ken Fengler We want to give a huge thanks to KEN FENGLER for his 12 years steering the ship at International GT! His leadership has given us this wonderful racing series that we all enjoy!! We wish him the very best in his retirement. Although we all expect to see him again, he swears his plans are to sit on a Florida beach, cold drink in hand, with his only worry in the world being which coconut might fall on him! For those not at COTA click on the photo to hear Ken’s closing podium. Thanks to Cam from Matrix Motorsports for providing the video!! Circuit of the Americas Season Finale Racing is BIGGER in Texas International GT headed to Texas for the 2025 season finale. We ended the weekend with some fantastic, very tight and spirited racing without one single caution lap! Circuit of the Americas is arguably the top-rated racing facility in the US and it’s always fun to see it right after the F1 race. The weather could not have been better most of the weekend, with the only exception being Saturday afternoon when sprint race 3 was canceled. The rain had stopped, and track was drying but the lightning was active and we were finally delayed to the point we were encountering darkness and had to cancel the race. Above and beside are iconic sites at Circuit of the Americas brought to us by our own Marie Zitza (Ron’s better half). The main entrance marquee above the karting track and the observation tower lit up at night. For this report, we’re starting at Maranello Cup as our

Fast, Safe Racing Video – IGT Record Season, Watkins Glen Reset
You’ve heard the old saying “knock on wood” when something is on a positive streak but we say GOOD JOB to all the 2025 International GT competitors for marking 6 event weekends without any cautions for car-to-car contact!! Even with large fields and tight starts (like the one in the photo from March at Road Atlanta) everyone has raced clean and safe!
Click on the photo of Tom Kirk’s 22A to link to a video from Mid Ohio’s enduro showing exactly what we mean. Fast, fun, competitive, safe racing!
Admittedly, there have been a few off-course adventures taken by single cars but no car-to-car contact resulting in caution periods. We say big KUDOS!!
We’re well past the half-way mark in the season with just four races remaining and we look forward to more of the same super fast, safe and conscientious racing throughout the final events of the year. KEEP IT UP!
