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.
This one has no bump steer either..

And of course guys you can put the tie rod out front and also have proper akermann, they can co-exist. As long at the steering arms are bent out wide enough, tucked into the wheel unfortunately. As long as the line between the tie rod end pivot point and the center of the rear end housing goes thru the king pins.

No, actually they do exactly as they were designed to do. When man was first trying to figure it out, no they didn't fly, because they were trying to fly like a bird. But the design of the wing was done on paper long before one was made. It was proven on paper with mathmatics that the air going over the top of the wings shape would take more time thus creating lift by the air under the wing. This is a scientific principle that makes it work. Many people would have died trying to simply make things fly if this principle hadn't been created on a piece of paper with a quill pen.

I understand but then after it was done on paper it showed that it would. It isn't like the bee which on paper is isn't suppose to fly. The helicopter on paper does fly, the lift created by the rotor (which is shaped like a wing) over comes the weight of the body. They weren't able to pull it off until it was done on paper.

more akerman.

My brother used to race go-karts, When the geometry was wrong you could actually feel it turns. He let me drive his fast one a couple of times, He used a triangle plate with the front tierod, the left tie rod hooked to the right side of the triangle, and visa-versa, that put the right akerman back in, With the backwards akerman, and bigger tires than on a lot of T buckets, when you hit a bump the tire with the most traction decides which way you go, and I have had one car I built cross the white line on a bumpy turn with traffic coming towards me.

I don't spend much time at all on forums anymore..
Now I remember why.
DeeW,my point to you was,if you're building the frame from scratch,
follow the basic 4" dropped axle spring on top,stamped crossmember,
cross steer,and you will have a solid chassis.
Also be sure to use tie rod ends on your tie rods,and not heim joints.
Forged steering arms. Don't fall for the cheap prices online,buy American and you will
only need to buy it once.

man, most of the cars with spindles that got hit in the nose, or bumped a curb. and bent the tie rod arm on the spindle are running around with ankman totally f up
yes you should address it, if you can.. if not.. you "might" get tire wear.. my bet is the tires will dry rot before you wear them ..

A little bend in the steering arm doesn't come anywhere close, not even in the same ball park, or city the ball park is in with what we are talking about. It's like comparing a rock chip on the hood of your paint job "ruining" it to pouring two gallons of Aircraft stripper over it.

And case you don't know it.. You can't make these lines meet at the rear..

since You guy's got it all figured out,, you need to tell me why these cars was built this way..

Must be why they started putting the rack's in the back...
