the 1992 Galmer car was short of downforce, which made it a pig on smaller ovals and road courses, but the lack of downforce (and the associated drag) made it very quick around Indianapolis. Also, 1992 was the last year before they changed the track in the corners to introduce a grass area between the bottom of the track and the entry/exit road. Before 1992, the driver of an understeering car could dive below the yellow line onto the apron to balance out the understeer. You could see drivers doing that a lot up to and including 1992. After 1992, the "dive low" option was no longer available, which hurt cars with insufficient downforce (including the Buick-engined cars, whose taller engine package created more drag and "hid" part of the rear wing, limiting their downforce).
