This setup is for the Rally League Season #3 Event #2 Ford RS200 on Rally Wales/GB.
The first things you will notice about the Ford RS200, the powerband is short, and it is a handful to control at any throttle position.
RS200 Handling Theory: Being a mid engine 4wd built exclusively for Group B madness, the RS200 is a beast. In order to effectively corner the RS200, you should have the car fully rotated, while applying 40-60% toward full throttle position as you corner. Only fully open the RS200 up (WOT) when the terrain allows your eyes to ensure you have a few moments to do so. This means that there should not be any bumps, jumps, dips, or elevation changes of any kind (you are not prepared for) with which to cause a loss of control. The rear of the RS200 will rotate and skip all over the place at WOT, so only use it with extreme caution.
3 Keys To Success:
1) Modulate the throttle (more so than 2/RWD)
2) Rotate the car prior to corner entry
3) Use the front tires to pull you out of over rotation or excessive slip situations
We will go in order according to the setup menus
Rear Differential: It is unfortunate you cannot control lock or preload, for this fact, diff tuning on the RS200 is difficult and can even change from stage to stage on event. I recommend starting low with the rear diff and increasing strength depending on how much understeer or over rotation you are seeing.
Gearing: The RS200 has a very short powerband. Raise the final drive for higher top speed and a longer powerband in each gear. Then increase the first 3 gears slightly if you need a little more to work with in those tighter corners.
