The 17.5 car required a bit more steering than the 21.5 car, so the setup was a bit more aggressive but still kept tame as to prevent traction rolling on the high grip surface.

The track was very high bite, especially the morning of Mains day. The car needed to be calmed down to be able to drive hard for the mains. This setup was created to keep the car calm and on 4 wheels.
