The Circuit
St. Petersburg is a very demanding track for the brakes due to the different types of road surfaces including concrete, painted sections and expansion groves on the short temporary 1.8-mile street circuit. St. Petersburg has seven braking zones and drivers will spend at least 20% of their time on the brakes. In 2015, Will Power set a new qualifying track lap record of 1:00.6931, which means he spent at least 12 seconds on the brakes on his fastest lap around the circuit.
