The floors of Romain Grosjean and Kevin Magnussen cars were modified in the zone located just in front of the rear wheels. The cuts were redrawn and their number increased to four instead of three.

These cuts, rather a lot of them, serve to bring high pressure air through the top of the floor and then direct it downward, to create a kind of skirt, which seals the sides of the diffuser.

Finally, the diffuser was reshaped and now looks more like the Ferrari and Red Bull ones.
