I am learning about how suspension setups work as I tune an in-game car (LeGran Wagon) to be more of a time-attack track car. In doing so, there are a couple of things I want to try with the suspension, and it would be really helpful if I could see the roll center of the front and rear suspension. Ideally, visualized by drawing thin lines with a large dot at where the roll center is (similar to the center of gravity debug and steering geometry debug). (It would also be nice in my opinion to be able to view the CoG without the CoP. The CoP debug point "buzzes" around a lot, and is distracting for what I am doing; that's a different topic though). This would be helpful for me for suspension tuning and modding. What do you guys think? (I'm okay at programming, and would try to implement this myself, but I have no idea how/if drawing lines/nodes like that would be implemented). After playing around some more, it would also be helpful to be able to grab the CoG like a node, to simulate the force of going around corners and see how it affects the roll center/suspension geometry, without having to get the car up to speed and drive it while watching the points.
I'm in the same boat, suspension is the thing that interests me the most in car tuning, but i can't seem to find the info in game files, or anyone else that's done it as a ui app.
