Sorry new interiors, but i agree with Brian. It has been a while since i posted but thought it necassary now. Ackerman has been known since the model T days by henry Ford. and is still incorperated into the newest cars, be they be a Honda
, ferrari or a pantera (one of my cars) Look in any old engineering book from the 60s when I was in college. In any turn the inner wheel turns at a smaller radius than the outer wheel. Ackerman solves this. When turning left or right the inner wheel will turn slightly more than the outer wheel.

This is just one consideration. What about toe in? Slight toe in is cool, any toe out IS NOT! Look at any align specs.

How about pos. castor, on my gasser I cranked in 6 degrees. the gasser always went straight (pos. castor leans the wheels and lifts/leans the body sligtly thus pos castor will make the car tend to go straight with no correction)

Bump steer, early panteras and many cars had that problem. It was because the steering linkage was not aligned with the suspension. This was solved on my pantera from the factory with 1/4 inch spacers on the rack and pinion.

SLA control arms, my C2 vette has them. They were designed to keep the front tires from scrubbing.

Thanks for the Lesson..
You miss the point I was making..

I've done more then a couple chassis...

[VAPHEAD]

five pic's at a time?..

Me too..
I see you like one type of frame..

[VAPHEAD]

see five more..

[NEW INTERIORS]

Keep them coming..
Looking good so far..

[VAPHEAD]

more of a street rod chassis for ya.

Like I said,follow Ford's design basics in the front end.
It works.That's what I do.

If that work's for you.. Great.. Keep up the good work..
As you can see I step outside the box a little more then others..
I don't like every car I build to look like ford built it.. That's all..


Thinking outside the box allow's you to build things like this..

What was the point you were making?? No offence is intended. A squared frame? Look at your pic 5
I have a reversed corvair steering box on my gasser just like in your pic. The difference is that I mounted the box on the frame so the pitman arm was excatly at the center position axactly right along side of the radius rod mount bolts. Then I
positioned the foreward steering link exactly as long as the rods are. No bump steer. This is Imprtant on a gasser going through the quarter as I had enough to think about, 11 seconds at 128 and shifting. Holding the steering wheel straight was a no brainer, just trust castor when pulling whelllies on a gasser.

Now this will look like a quick google job but I learned this 36 years ago at that rod shop when I was 17 and never forgot it, the Akermann angle was created (discovered?) by Ralph Akermann in the 1860s! Before there were even cars, this principle existed, pretty cool stuff.
