The former British Rally Champion achieved speeds of up to 162 MPH (260 km/h) and a lap time of 19 minutes 37 seconds over the 37-mile track, which runs through several small towns with trees, stone walls, and buildings and includes more than 200 corners.
The video highlights Higgin’s lap that averaged 115.356 MPH, while the British driver also talks us through a chilling moment at Brey Hill when he momentarily lost and then regained control of the WRX STI at more than 150 MPH (241km/h).
Aside from the necessary safety modifications such as a Lifeline fire suppression system, Hockley Motorsports roll cage, and motordrive competition seats, the WRX STI was also fitted with Mintex brake pads (but with stock calipers and rotors), a louder open exhaust to warn spectators of its arrival, and retuned springs and dampers to accommodate the numerous high-speed jumps on the circuit. In addition, Subaru’s engineers turned off the car’s speed limiter.
Commenting on the event that marked the test runs, Higgins said:
"We were only able to get two practice runs and on our second practice I had the biggest 'moment' of my career. We had a passenger on the run and so coming into Bray Hill at more than 150 MPH, the extra weight compressed the suspension more than on previous runs and shifted the Subaru to the left and then right as I corrected--it was a real tank slapper. The whole thing went by so quickly that we never slowed below 110 MPH, and then we were back on the power. It was amazing and the helicopter shots really show just how hairy it really was."
