All your setups are basically the same for every car. I don't really think these are real tunes, this guy just turns everything up a little bit for every car and calls it a tune.
Does it work? Does it help to keep the car a bit more stable?
I does for me. And yes they are tunes and no they are not all the same, I know some car types (BMW) as an example have some very close models where the adjustments work very well and are very close to each other with just some minor differences.
Other cars have about the same weight/power ratio to each other and very close characteristics so you will see many close tunes like that. I addition, the available limited adjustable settings combined with my racing preference will determine settings to be a certain way. I prefer stiffer shocks and rebound/compression. It's my preference.
Further more, this is a new game with different physics, some realistic, some not. I think most tuners, like me are learning the ropes here and developing a feel for how cars respond, how the tunes react to different types of tracks etc.
My goal Is to learn and in the process help those who don't have time or calling for tuning. It's a start, and it's me dedicating my time and resources to help others as best as I can for free with not strings attached.
If the car turns out to handle nicely and I am happy with the settings for now, It is what it is!
Sorry you don't like them, there are plenty of other tuners here to help you out. Have a nice day.
