Please post any links to online calculators in this forum thread.
You can post suspension or Engine calculators here, but please give a short explanation of what your calculator does.

Here is a page on how to calculate your suspension frequencies http://www.racingaspirations.com/apps/wheel-frequency-calculator

Here is an engine calculators I use for displacement, compression, boost, and altitude. It is primarily focused on motercyles, but the four cycle engine data is the same regardless of # of cylinders.

(i've found it to err to the large side, you can pick the next size down and probably be ok)

Rear steer calculator. Not sure if it is accurate or not.

[BillyShope]

Not sure if it is accurate or not.

If the picture's correct, I don't see how it could be. He appears to be showing Heims at both ends, but no upper link. Rear steer is determined by more than just the angle of the lower link.

This is a reprinted SAE paper on the geometry of wheel caster, including the derivation of the equations related to measuring it on your vehicle.

Warning, gratuitous use of trig.

Here is a site with a materials weight calculator with what appears to be a pretty comprehensive materials index. Tell it what type of metal alloy and of what dimensions (for all sorts of materials - round tube, solid round, square, flat sheet, etc., etc.) and it spits out the total weight. Pretty handy.
