Just a few minor modifications (a couple which will stay for the rest of the season) around the car. New front wing (Monaco specific, extra downforce and stability), new rear wing, new Y100 (monkey seat), a new diffuser and a few internal mechanical changes.
Here are some pictures
The only new thing on the RWEP are new slots, slightly reprofiled for better airflow.
New flatter profile on the rear wing upper and lower planes. Upper plane is also slightly larger for a little more downforce.
Next update will be Silverstone as there will be a slightly lower downforce configuration for Canada and Austria due to both circuits having long straights.
