American racing star Chloe Chambers made an encouraging debut in Lamborghini Super Trofeo North America at Sebring International Raceway, finishing seventh and ninth in the ProAm class while demonstrating highly competitive pace and top-five potential in her first outing aboard the Lamborghini Huracán Super Trofeo EVO2 with RAFA Racing.
The season opener at Sebring, one of North America’s most demanding circuits, renowned for its notoriously bumpy surface, marked Chambers’ first appearance both in the Lamborghini one-make championship and on the IMSA platform. After two seasons competing in F1 Academy, the American driver stepped up to GT competitions once again, sharing the #81 entry with fellow rookie Ian Porter in the ProAm category.
Although new to the series, Chambers was not unfamiliar with GT machinery, having previously impressed during two seasons in Porsche Sprint Challenge North America, where she delivered multiple dominant performances. The Sebring weekend however served both as a competitive debut and a crucial learning opportunity as she adapted to a heavier, higher-downforce Lamborghini platform in one of the toughest GT one-make series.
Porter handled qualifying duties for Q1, posting a 2:05.037 that secured 23rd overall and seventh in class on the grid. Chambers then took over for the second qualifying session and made a significant step forward. Her lap of 2:03.566 placed the #81 Lamborghini 14th overall and fifth in ProAm, highlighting rapid adaptation to the car over the previous practice sessions and providing momentum heading into the races.
Porter started Thursday’s opening 50-minute race from seventh in ProAm under clear skies, with all 39 cars navigating the notoriously tricky Turn 1 cleanly despite a mid-pack spin by Ware that fortunately avoided triggering a caution.
Porter immediately capitalized on early incidents, climbing into fifth in class and leading a tightly packed group of cars during the opening laps. After briefly holding position, he slipped to sixth following a pass by Siderman but maintained consistent pace as the race remained green despite several minor spins elsewhere in the field.
As the pit window opened with 30 minutes remaining, Porter brought the car in from sixth in class, handing over to Chambers for her first competitive Lamborghini race stint.
Shortly after taking over, Chambers experienced a small off-track moment but recovered quickly, rejoining in seventh position and maintaining composure amid intense midfield battles. While many of the fights around her were not directly for class position, she kept the car clean and began steadily improving her pace.
Once settled into rhythm, Chambers’ speed became increasingly evident. She consistently improved her times, closing the gap to Kyle Marcelli ahead while continuing to make progress pace-wise. Her lap times dropped progressively as confidence grew, showcasing pace capable of challenging for the top five.
Despite margin to close ahead proved too big for class position, Chambers completed a strong debut stint and brought the car home seventh in ProAm, a solid result that reflected significant improvement across the weekend.
For Friday afternoon’s second race, Chambers took the start herself after making substantial gains in pace during Race 1. Starting fifth in ProAm, she launched cleanly amid the nearly 40-car field, climbing to 12th overall while maintaining her class position.
Quickly clearing a Pro-class competitor, Chambers gained clean air and began closing on Graham Doyle ahead in the battle for fourth in ProAm, once again displaying increasingly competitive pace.
An early incident involving Tasca left debris on track and triggered a full-course yellow on lap four, interrupting Chambers’ momentum just as she began building a gap. Racing resumed briefly before another caution followed when Lawley crashed at Turn 14, limiting green-flag running during the crucial opening phase.
Despite the interruptions, Chambers held fifth in class and remained poised during restarts. As pit stops approached, Doyle made a small mistake with a wheel off track, allowing Chambers to apply pressure as she positioned herself to capitalize.
When the pit window opened on lap 11, Chambers pitted from fifth in ProAm and handed the car to Ian Porter. After the driver change, Porter initially ran sixth but lost positions to Tandon, Miller, and Siderman, dropping to ninth in class. Running consistent 2:07 lap times before improving into the 2:06 range late in the race, he attempted to close a six-second gap to the next car ahead, but time ran out before further progress could be made.
The #81 crew ultimately finished ninth in ProAm, completing a challenging but educational weekend.
“Lots of firsts this week in Sebring, but also lots learned for the whole RAFA Racing team,” Chambers commented. “Ian [Porter] and I got thrown into the deep end with a promotion to ProAm with much more experienced drivers, but we made solid improvements on one of the hardest tracks of the year.”
Chambers and Porter leave Sebring with six championship points and valuable experience gained at one of the most demanding venues on the calendar. While results did not fully reflect her pace, Chambers’ competitive race speed highlighted potential moving forward.
The Lamborghini Super Trofeo North America season continues May 1-3 at WeatherTech Raceway Laguna Seca, where the RAFA Racing duo will aim to convert their growing confidence and stronger results.
