Brabham again topped the time sheets during the Thursday morning pre-qualifying session, with Stefano Modena fastest, but the Dallara of Alex Caffi was only 0.141 seconds behind. Third was Pierre-Henri Raphanel, who put in a fine performance in his Coloni, pre-qualifying for the first, and ultimately, only time. The fourth pre-qualifier was the other Brabham, driven by Martin Brundle, who edged out the Osella of Piercarlo Ghinzani by just two-hundredths of a second.
