As Denstjiro mentioned. It's a series of 4 sliders that rFactor featured. Downforce, gear ratios, suspension stiffness, and oversteer/understeer. It made for a quick and handy way for people to adjust a basic setup on their cars.
With that many things out there to help you learn how to set up a car. it would be best to use these and learn then you will get better for sure as the car setup would be to your driving style.
I recently moved from RF1 to RF2 and miss these basic sliders. They are a great starting point when you are in a new car or new track. As much as we think we know about car setups etc... My lap times were always the best after starting with the basic sliders then moving from there. So I would also like to see these sliders come back.
