The former Formula One driver alongwith team-mate Jan Seyffarth had initially qualified in 16th position. They finished eighth in the qualifying race before finishing fourth in the main race.
The race pace for Seyffarth Racing seemed to be a lot better than qualifying as they moved up the order in the qualification.
In the main race Chandhok had a great start as he quickly moved up to sixth place at the end of the first lap. His team-mate Jan Seyffarth took over for the second half of the race and held off Alvaro Parente off Loeb Racing to finish in a brilliant fourth place.
"To move up from 16th to 8th in the race was excellent and the car felt great. I managed to set the 5th fastest lap in the race which clearly showed our car improved," Chandhok said.
"It was tough as the cars ahead of us were much faster. Jan also drove well and did a great job holding off Parente in the last part of the race. After the Le Mans recovery it was good to have my best finish in the FIA GT Series.
