A body sports car handling

I would like to ask, whether this post might of had been titled incorrectly. Not to insult anybody, but if you need to question how to make a suspension more efficient, are you really ready to be doing massively illegal driving on the street. I think I would tune what you have, and get used to it first. If you've seen the Hotchkis challenger, and you've been around awhile, you'd know they didn't invent the wheel or anything else. They only conglomerated ideas into a package that guys have been using for years. The materials are better, but the way people used to build these cars is no different today than 30 years ago. Look up Dan Gurney.
Once you get your dancing shoes shining, than modify it more as you grow with it. It's like going from a go-cart to indy. If you learn to suspension, you will truly learn the suspension grasshopper.
