for you guys running custom suspensions do you know what your geometery is? I am getting ready to lay mine out but I have no idea what range I should be shooting for on everything (roll centers and such) caster and camber will have plenty of adjustability in it so I am not too concerned about that one.

Do you have any software?????? I'm sure Dennis or someone will chime in here and let us know what is good and what isn't! I would like to find a decent software program to play with!

Well then you should be able to put in all your measurements and ideas and test it????? Right??????? I'm not for sure but like you would like to know more!

Herb Adams "Chassis Engineering" book should help you get in the ballpark.

I have read that book several times it is very good

Having the software is one thing. Knowing how too interpret the info is another. If you already know how to read the info, then you should not have any problems. Otherwise I would contact someone who lives and breathes suspension analysis to help you out. That is what I did and was one of the smarter things I have done.

I got the herb adams and the staniforth book.....but they both just seem to describe what everythign does not what range of values a street car has. staniforth does talk a little about natural frequency of a luxo barge, sports car, built street sports car, mild track car, full track car...then then F1...

usually you will be working around variables or givens that will only permit a basis for the intial design, the idea with the software is to be able to run several simulations on minor changes, and what they will do to the over all picture. the whole layout is a bunch of compromises trying to get the best overall with taking every aspect into consideration.

my advise, input your givens, see where your at, then figure out a way to make it better. then when your all done.... let somebody who really really understands everything look it over.... btw..thanks dennis

Give me your numbers and plug them in, I use Wingeo3. Before spitting out a bunch of numbers it is pretty important to know what type of suspension you are going to be running F&R, intended purpose (realistically), and what type of car it is.

I PM'd a link to my proposed design analysis.
