Subaru driver Mark Higgins set an all-time fastest lap, averaging 115.356 mph on the iconic Isle of Man TT Mountain Course and hot-shoeing a U.S.-spec ’11 Subaru WRX STI. (The previous record of 100 mph stood for 21 years.) The lap took 19 minutes, 37 seconds and the WRX STI hit speeds in excess of 162 mph on the 37-mile course.
The WRX STI was a production U.S.-spec car running a standard 305hp turbocharged boxer engine. The Subaru was equipped with a Lifeline fire-suppression system, a Hockley Motorsports rollcage, competition seats, Mintex brake pads (but stock calipers and rotors), and an open exhaust to warn spectators of the oncoming car. The speed limiter was turned off to allow a higher maximum speed, and springs and dampers were changed to accommodate the numerous high-speed jumps on the circuit, sending the WRX STI almost 4 feet off the ground. The car ran on street-legal Pirelli P Zero Trofeo tires.
