though I doubt that it'll do what you're looking for. AFAIK, there's no one who's able to put together detailed enough models to truly simulate a production car.
For example, if you wanted to see the result of changing spring rates, you'd need to know the exact suspension geometry and parts, materials information on the metals used in the arms, flex characteristics of all bushings, assumed frictions of all moving parts, and likely more stuff (I'm not an automotive engineer, I just play one on the weekends). And this likely would be one of the more simpler analyses.
For example, I would guess that modelling properly something as commonplace as an exhaust replacement would be ridiculously complicated. Since you'd be optimizing flow through the engine, you'd need to understand flow details of all the components in the stream. I can't see any of the auto manufacturers releasing this information to the public, or any way for budget-limited hobbyists to obtain it.
Finally, you could probably forget aerodynamic modelling without a 3-d CAE model. That's all black magic there. I have, however, considered putting the 1:18 scale model of my car into a 1:18 scale windtunnel...

There's some software here:
