Sandy Mitchell and Rob Collard clinched both the Drivers' and Teams' championships for Lamborghini and Barwell Motorsport.
Rob Collard led from pole at the Silverstone 500, keeping title rivals Patrick Kujala and Sam de Haan in the Ram Racing Mercedes behind from the rolling start.
Mitchell and Collard carried momentum from a Pro-Am class victory at the Spa 24 Hours into a championship-clinching performance at Silverstone just weeks later.
Phil Keen and Adam Balon finished ninth at Silverstone despite a late-race incident, and those points pushed Barwell Motorsport over the line for the Teams' championship.
Mitchell and Collard did not carry a success time penalty into their third and final pit stop, a regulation-mandated advantage no amount of driving talent could recover on track.
Mitchell and Collard scored two wins and finished every race inside the top five, a level of consistency rare in GT3 racing where contact, mechanical failures, and balance-of-performance swings routinely shuffle the order.
