Now that I know that I can fit in the chassis, the next step is to select the tires. Good tire data is hard to come by but I've found what I needed. Once tires were selected then it's on to the front suspension. Now I've chosen the wheels and know the space I'm working in, I've picked out the brake rotors, and calipers. Wheelbearings and steering rack are next.
So far I have a ton of notes and have done some basic calculations. Once it gets into actual suspension design, I'll use a computer for that.
