Rules back then stipulated maximum width for a wing placed behind the rear axle
Toleman installed a mid-wing just forward of the rear axle, complementing the standard one:
Others extended the rear wing endplates forward of the vertical plane passing by the rear axle, so they could have wing extensions outboard of these endplates:
This Tyrrell solution kept the width of the wing located behind the rear axle at maximum width, but its delta shape permited for it to be extended further. Notice that the endplates in that Tyrrell also are fully located in front of the axle. It was the most "colourful" solution, but also the least successful one.
