Car Run in Ralley

1.    Special car built by Lamborghini chief mechanic Bob Wallace who thought that Lamborghini cars should be less about comfort and more about speed.
2.    So he took a Espada body, stiffened it, put a rollcage on it and mounted the engine further back in order to achieve a better balance.
3.    Rolling on Miura wheels with Michelin XWX tires with ventilated disc brakes, the Jarama Rally was further "lightened" by cutting away sections of the floorpan and replacing them with aluminum.
4.    Instead of glass, Wallace used plexiglass which was lighter.
5.    The need result was a 300 kg reduction of weight.
