Post Understanding double wishbone (a arms) suspension

Hi
I want to design double wishbone suspension for a street buggy, problem is I know nearly nothing about it 🙁 . My question is where do I start. Obviously I did some research and I know there are few things to consider:
- kingpin inclination
- scrub radius
- camber
- caster
- toe in/out
- roll centre
- gravity centre
I know what are they but I don't know what the values should be and should I consider them when car is stationary or when cornering 😕
I would appreciate any help for novice

Hi Sylvester
As a novice as well, I had the same problem but found much of this information in Carrol Smith's book Tune to Win. His earlier book Prepare to Win is also helpful. However just by chance I came across a wealth of good information on a Locost and Haynes Blog link super7thheaven.co.uk Open "components" in the menu, click on "Sierra uprights" scroll down to "related" and open "Anti Dive Geometry." Again scrolling down to "related" you will find what you require. It however took some time to digest all the info and learn to use it with the Racing Aspirations calculator.
Good luck with your project.
