Approach
The goal of this setup was to create something that is drivable for a variety of players. The target was to have a predictably rotating car in all driving scenarios. That means it rotates in a similar way on the brake, on throttle and during coasting. At the same time I wanted to avoid the negative toe that often leads to the car being half sideways in every corner.

I hope this setup has achieved that and the inputs indicate it did.

Adjustments
The setup is on the stable side of things. Especially for a race scenario you might be able to handle more rotation. Tire wear is balanced and with the increasing front ride height throughout the stint the car will get more understeery. That means the more oversteer you can handle at the beginning of the stint, the better the late stint behavior. 

More oversteer (general/mid turn):

• Increase rear ride height
• increase front splitter
• stiffer rear spring/softer front spring (try the latter first)
• less wing (big impact)

More oversteer (brake/entry):

• reducing preload will give more rotation off throttle, but it immediately gets tricky into the fast right after the straight. 140-150Nm seems minimum.
• increase front bump stop range
• reduce front bump stop stiffness
• decrease front bump damping / rear rebound damping

More oversteer (exit):

• decrease rear bump stop range
• increase rear bump stop stiffness
• increase rear bump damping / front rebound damping
• While reducing TC2 closer to 0 will help rotation, I'm not convinced it helps lap time

Driving
Typically with the esports setups the Porsche almost requires you to use the throttle mid turn to keep the rear in check by locking the differential, while trailing the brake will almost lead to a spin. This is not the case with this setup.

• The car is fine off throttle and it allows you to use the brake to control the amount of pitch and rotation you want into the corners, especially the faster ones.
• The data should show gentle trailing to control the car's direction and rotation.
• That way the Porsche is driving more traditionally and makes transitionining from or to other cars easier.
• However, the on throttle behavior will lead to understeer if you apply it too early
• Most apexes will be late, i.e. after the middle of the corner
• In some turns like T2/3/4 it can be beneficial to not just slam the throttle, but progress to max over, say, half a second to not lock the differential immediately and keep rotation initially and TC interference at bay
