Ferrari F2007 - rear wheelnut extension 17 March 2007
Last season, Ferrari adopted shields to cover the rear wheel rims. These additions meant the mechanics could only access the wheels with their wheel guns through a small central hole. To improve the timing and precision of this operation, the F2007 has been fitted with a wheel nut extension, which enables the mechanics to fit the wheel gun onto the nut more easily. This modification has already improved the timings of the team's pit stops.
