Setup Sheet

Your teacher is running this lesson a piece at a time. The rest of the sheet appears here as they unlock it.

The track

This is where you are driving. Every track asks the car a different question.

Race somewhere else

Long straights want a slippery car; tight corners want grip. Each track keeps its own setup, so moving to another one does not lose your work.

Set the car up

Five settings, and every one of them is air: the wings and the floor. Change one and watch the drawing and the numbers move.

DRS Lets the driver lay the rear wing flat, anywhere on the lap. While it is open almost all of the rear downforce has gone: free speed down a straight, and a spin if it is open in a corner.

Fit the wing you designed in Airfoil Lab

Rear wing section

In Airfoil Lab, simulate your wing, then press Use as a car wing in Shell Lab and copy the link from the address bar. Paste it here.

When the car looks right, go and drive it. Nothing on this page guesses a lap time: the only one that counts is a lap you set yourself.

What that does

Worked out with the same physics RaceSim drives with, so the garage and the track agree. Each number is compared with the standard setup.

What the driver said

Come back from a run and describe how the car felt. The garage finds the number behind the feeling and the smallest change that answers it. It will also tell you when the numbers disagree with you, which usually means the fix is in the driving.
