As far as using them on the rear mounting points of hairpins goes, I don't feel like it matters much whether you use tie rod ends, Heims, or urethane bushings. Hairpin radius rods are marginal at best for use in a solid axle suspension system. I'll take a 3 or 4 bar system any time.Might not be very "traditional", what ever that is supposed to mean, but they give a controlled freedom to the wheels to react to road variancies.
Here is an example of what I think amounts to a working front suspension:
Anyone, please feel free to critique it or question about it.

You can see how much range of movement is at the rear with the 4-bar. Actually it is greater than that as the coilover on the left is still in the middle of it's travel.
Much less stress on the frame with a suspension that works and these ladder type of frames need all of the help that they can get.
Just my opinion. :funmeter2:

Suspension yes in a way, but not really, as the tie rod and panhard do not suspend anything, only turn wheels and they do not ever use tie rod ends for Panhard bars, ant factory that is, so I should always make myself very clear it sounds like, Sorry if I did not explain it well enough, but again this is how I learned it, who knows, I can be wrong also... What I talk about here is how and what I do on my car and cars I build.. I do not mean to tell anyone else what to do on your own car, at least I do not mean too

GAB, I did not mean to be telling you not use the tie rod ends in the place that you are using them... I am just not a real fan of using them on/in high side stress areas like lift type radius rods, like you say, a 4 bar is not a side stress unit, sorry for the mix up, your setup is a great one for comfort and a super ride with no real stressing to the frame... :jh:
Have you got any closer pictures of the frontend?

This pic may help some of you see the reason for using a 4 Bar suspension configuration for locating and controlling wheel movement. The right front wheel has been raised 10" and the left front remains on the ground. While this is an extreme and that amount of travel is prevented by the range of the coilover unit, it shows the degree of freedom of movement. I don't think that you will find too many hairpin configurations that can achieve this kind of movement for one wheel independent of its axle partner. It is that freedom of movement that allows frames to be lighter as the suspension is not trying to twist it torsionally at every deviation in the road. The frame on this car is 1-1/2" x 2-1/2" x .083".

Would like pics of the bars at the front axle and the bars at the frame brackets. Thanks
