A brief note about suspension design

It's complicated.

Okay, so I need to finish building the frame. But first I have to design the rear suspension so that I know where to build the inboard mounting points. And while I do that, I have to design the front suspension so that somehow they'll work together (as if I knew what I was doing).

From what I've been reading of Carroll Smith in Tune to Win, I think my major goals for the suspension are:
  1. Keep the laden (outside) wheel as vertical as possible during roll (without requiring gobs of negative camber at rest).
  2. Keep the track width as consistent as possible.
  3. Also, I'd like to be able to drive around without clipping the top of every 1/2 inch pebble.
I'm trying to not get too wrapped up in every possible detail that could affect the outcome of the design because:
  1. I really don't have any idea how certain features of the car are going to turn out... like the weight balance. And even if I did, I wouldn't know how these would interact with the suspension.
  2. There are just too many things to worry without going totally crazy.
So I just want to focus on a few parameters, build something I think might work and then try it out. Hopefully it'll be adjustable enough to work out minor problems, and if it's a total catastrophe, I can just redesign it (with my wealth of knowledge gained from having tried it once already).

Here's a sample of front suspension design layout:



Wow that image looks like garbage. I think my computer found out that I hate it.

I think I'll sleep with Mr. Smith's book under my pillow tonight-- maybe I'll wake up with the answers.
