Full boost hits and the 1995 Porsche 911GT sends the full impact of 0.9 bar to the rear wheels, and the rear wheels alone. The 285-section rear tyres squirm, threatening to swerve the distorted, riveted wheel arches across the road, and all I can do is keep my right foot pressed hard down. The 993 GT2 – as it’s more commonly but less accurately known – has a reputation. Mixing the twin-turbocharged engine from a contemporary 911 Turbo with the thin glass and skeletal interior of a 911 Carrera RS, while equipping the driver with nothing more than ABS and power-assisted steering to fight their corner, the 430bhp GT is The Widowmaker.
