I think you really need to do some thinking on this one. Designing suspensions, especially independant front and rears, is really easy. Designing independant suspensions that ride, corner, handle and steer well, all at the same time, is very difficult. This is what I do for a living and believe me it is a complicated job.
If you don't have the knowledge or equipment to do the job correctly you will get frustrated very early and your project will never get completed.
"Starting" with a component from another car can be done but you need to know that this "start " is short lived and, unless you copy the other cars geometry exactly, your suspension will never ride, corner, handle or steer well. Taking all of the variables into consideration, especially when you start changing control arm pick-up points has to be done, otherwise you will have a very ill handling vehicle.
Now, don't take me wrong here. I am all for the do-it-yourselfer but, when I can see that that person "MAY" be pushing the envelope of their knowledge and skill I do get worried. I am not trying to talk you out of this, all I want you to do is sit down and think about what you are getting into. If the knowledge and skill is there, more power, but if it isn't, I think you should set your sites a little lower and build something a bit simpler to gain knowledge and skill.
S10's are one of the most well supported vehicles in the aftermarket in all aspects and you can build a real corner carver with bolt on parts. Holler back and let us know what you think...
