Weight repartition is just not matching with springs value for all cars.Hello my friend, stumbled on to something that might spark that light bulb into tuning mire cars. Goggle gt5 weight distribution calculator. I know it says gt5 but suspension is suspension. It's pretty self explanatory. I've tried it works good, just need a different opion. What if does is set suspension anti roll compression extension stiff ness % off weight distribution. try it out let me know what you think.
Understeery cars would need a softer front springs and/or stiffer rear springs
Oversteery cars would need a stifer front springs and/or a softer rear springs.
I prefer to play on this parameter first , then on ride height together if not enough or if needed to use too extreme settings.
So for me, no calculators can do any kind of magic for springs.
