The near standard AWD Conti, also owned by Kankkunen, managed to reach a top-speed of 206mph (331km/h) but for the purposes of the record, only average figures were used. Despite the GT’s exceptional mechanical grip and the addition of spiked Nokian snow tyres, the car still experienced wheel-spin at speeds in excess of 120mph. Modifications to the car, other than the studded tires, included a full roll cage and minor aerodynamic tweaks, but the drivetrain remained untouched.
The rules of the attempt is that the ice must be formed naturally and cannot be treated with any chemicals, while the tires must be street legal in which ever country the attempt is being made. When travelling at 200mph, each stud on the tire exerts up to 2.2kg of pressure and covers a distance of 90m per second.
