No mention of it in my suspension book, so I guess it really doesn't matter either way. Are you going to use the original Ford set-up but with the
steering fixed?

No, I think castor is meaningless at the rear!
It is just to help the steering function as far as I know.
It exists of course but may play more part in anti-dive/squat functions.
I wouldn't worry about it, I didn't

I think that's best, I set mine vertical.
It's complicated enough already without more angles

Women are just like machines, press all the right buttons and they will do exactly as asked, press the wrong buttons and they will do exactly as not
asked, the real problem however lies in the 99% of time when you are not pressing any button.

and if it dont have 4 wheels and four strokes itll be a bitch

rear end castor
Camber and toe are the usual areas of concern at the rear end, but induced castor is used for anti-dive.
I wouldn't worry about getting into that, just keep the upper and lower wishbone pivot axis parallel.
Cheers, Bob.

rear caster
I seem to remember the subject of caster on the rear wheels being discussed by Mark Ortiz in his monthly newsletter. You can get his newsletter by
subscribing by sending an e-mail to him at markortiz@vnet.net and you can get back copies by asking him for them at the same address.
BTW, if your wondering who Mark Ortiz is, he's a chassis consultant for racing teams, he really knows his stuff, plus he has a column in Racecar
Engineering Magazine

Castor answer
To answer the castor issue, the reason we have castor is to straighten the wheels after turning and letting go. This is positive static stability.
We use the law of gyroscopic precession to take the applied force (the force the road exerts on the tire) and rotate it 90 degrees ahead on the plane
of rotation and exert the force there instead, which pushes the wheels straight again. If this is a bad explanation, go to
science.howstuffworks.com/gyroscope or just search for it in howstuffworks.com
