Subaru America has released the video of the 2011 Subaru WRX STI’s Isle of Man TT Mountain Course record run. Driving a US spec 2011 Subaru WRX STI, by multiple rally champion Mark Higgins, he managed to lap the 60 km course in 19 minutes 37 seconds with a top speed of 162 MPH. Making it the fastest production car to lap the course.
This particular WRX STI was a production US spec car running a standard 305 HP turbocharged boxer engine. However, some safety modifications were made, such as fire suppression system, Hockley Motorsports roll cage, motordrive competition seats, Mintex brake pads with stock calipers and rotors, and a louder open exhaust to warn spectators of the on-coming car. The best part was, the speed limiter was turned off to allow a higher maximum speed. Off-the shelf Tien springs and dampers were added to accommodate the numerous high-speed jumps on the circuit. As for the tyres, it ran on street legal Pirelli P Zero Trofeo.
Watch the highlights below for the run and also with Higgins talking through the “moment” at Brey Hill when he momentarily loses, and then regains, control of the WRX STI at more than 150 MPH.
