Suspension geometry calculators and "power charts"

I debated a while as to whether this would be better suited in here or on the suspension board, but I figured suspension geometry has a lot to do with launch and handling, thus a tech tip for both drag racing and auto cross. This site also has hp/et/mph calculators, 1/8 to 1/4 conversion calculators, and literally hundreds of various race and design discussions/explainations.

I use Billy Shope's calculators quite often, which can be found here:
http://home.earthlink.net/~whshope/
From the main page you can then select various suspension types and plug in the numbers.

Re: Suspension geometry calculators and "power charts"

I promissed a few people that I would post up the info/site I use, as the IC angle of a tq arm car and various other suspension questions seem to come up often.

Hope this helps at least a couple people understand how the system really works and how to properly tune it.
