Is something like this simple enough, and about what you guys are looking for?

It works great, the only issue with this calculator is that, since it is meant for full size cars they only go in pound increments for springs. But one with better hundredths of a pound results should be sufficient and hopefully easy enough for people to use.

I just started working on a spreadsheet that will do the same thing but with simpler required inputs. For example, having the total vehicle weight and F/R weight bias, instead of a specific corner weight, then calculate the corner weights from that. It will all be easily measured inputs, and I think will be a more than adequate simple calculator, especially for RC purposes (if this was F1, or other high level racing this would be a different story).

To be even more thorough would require a vehicle model either by someone writing it in a powerful computational program or by using a purchased vehicle dynamics software like OptimumK. If our little cars could be equipped with useful data acquisition (like linear pots on dampers, 6 axis accelerometers, etc), then we could definitely learn a lot more about them. However, even the EagleTree data acq stuff is too big and cumbersome for the little cars.
