I will also be doing Downforce, Brakes again (I learned some more stuff), Differentials, Toe, camber, and caster, tire pressure, and then how to optimize your tune. So stay tuned (the puns are real.)

Thanks! Need to check those videos. Always nice to learn from others how they do their work. By the way, is there a bug / poor implementation with tyre pressure when using “metric” units? Rather difficult to change pressure as you don’t see all the digits. Using English it works ok!
I’m not sure about any bugs with metric tyre pressure, but I will look into.
Pressure thing is easy to check. It works on metric system but there should be more digits to display. Here’s an interesting finding
Check your initial PSI first. It might be eg 30
Change to the metric system. And change eg. two clicks
Change back to imperial and check results now. You have 30.2 PSI. Normally you can change in 0.5 increments.
Was it me when you referred to “viewer” on your Youtube channel?

Thanks! Videos looked and sounded indeed very good! Good outcome, straight to the point. I liked.
I started to work on Civic '16 and Spring Rates. Details as follows:
Weight lbs 3047 (1382 kg )
Weight Distribution 65%
With your formula I got front stiffness 1287, which is out of scale? Did I miss something now
Yes, that is correct I know that seems heavy , but note that the car is front wheel drive and most of the weight is in the front. The formulas main use is to balance the weight of the car to the center from there you can reduce or increase the rate by 10% or 5% depending on you driving style.
One clarification. If I want to reduce oversteering. Do I apply -5% also to front or only to back?
You can keep up with my tutorials on my YouTube channel. An congratulations on your PB, but to your question on the reduction. There is a lot of factors that go into understeer and oversteer it could be your diff setting, toe,camber,caster,downforce, and tire pressure can have major impact on the car . My series is to teach people how to balance the car and what each setting does to help tune a car . I am working to get each tutorial out then finish with the fine tune episode. I do apologize that it is taking a long time to produce the episodes but I want to make sure it is simple to understand for everyone, and I don’t mind helping in the understanding of the method.
I was wondering actually this: "“you can reduce or increase the rate by 10% or 5% depending on you driving style.”
So did you mean that I should apply that to both front and back at the same time when adjusting?
Thanks for the conversion formula already. Quickly noticed that I need to use English system while calculating values. So that helps too, no need to change in between these systems in the future.
Yes, you would apply to both front and back
Thanks. And actually I had wrong formula in place. I did use Weight Distribution (twice) when needed to use 0,5 while calculating Spring Rate. So the result was not actually out of scale.
By the way, with this I had my personal record on my favorite test track. Let me know when you publish more tutorials. Very useful stuff!
EDIT: Seems that I got it originally right. Checked your video at it uses indeed w. distribution twice.
As of now I am working on a metric conversion for my formula.

enjoy!
That is an interesting find I wonder if there could be use for a more fine tune , and yes as the viewer in my video I just don’t know enough about the metric system in Forza and how it works
