It was a busy Easter weekend at Sonoma Raceway. As well as the GT World Challenge America, the circuit in California also hosted GT4 America, GT America and TC America, with plenty of success for the BMW M Motorsport teams.
The BMW squads were particularly dominant once again in TC America, with the BMW M2 CS Racing occupying the top seven positions in both races. Reigning champion Jacob Ruud was once again unbeaten, winning both races for Fast Track Racing in the #1 BMW M2 CS Racing. He was followed over the finish line in race one by Stephen Cugliari in the #57 Accelerating Performance car. Lucas Catania (Rigid Speed) was third in the #26 BMW M2 CS Racing. They swapped positions in race two, with Catania runner-up behind Ruud and Cugliari third.
In GT4 America, Austen Smith and Zac Anderson finished third in the Silver class in both races at the wheel of the #51 BMW M4 GT4 of Auto Technic Racing. Charlie Postins and James Clay, in the #36 BimmerWorld BMW M4 GT4, took victory in the Am class in the opening race. They then finished runner-up in the class in race two, followed in third place by Paul Sparta and Al Carter in the #98 BMW M4 GT4 of Random Vandals Racing. The best-placed BMW driver in both GT America races was Marko Radisic. He finished tenth and eighth for SRQ Motorsport in the #22 BMW M4 GT4.
