Later the team went to Monza, intending to run two cars in the 1951 Italian Grand Prix to be driven by Parnell and Walker, after prospective driver Ken Richardson was vetoed by the RAC. However gearbox trouble in one car led to Berthon, anticipating a similar problem in the other, withdrawing both cars. Disappointed, Mays' team returned home, but one car was able to remain at Monza for further testing due to the generosity of the track's owners, who allowed the team to run the car on the circuit and use the circuit's facilities at no charge. The car was the first Grand Prix car to use disc brakes: Girling created a set of special brakes for the car which were tested in late 1951 while still at Monza.
