Stefano Modena
As at the previous race in Brazil, the Brabhams were easily the fastest cars in the Friday morning session. Stefano Modena was quickest on this occasion, with Martin Brundle in second. Alex Caffi pre-qualified his Dallara in third, with Nicola Larini's Osella in fourth. Only four cars went through from this session now that the injured Philippe Streiff had been replaced at AGS by Gabriele Tarquini, who had left the abortive FIRST team.
