70 E swaybar?

[rich roush]

My 70E did not come with a rear sway bar and I would like to install one. Any suggestions? Should I go with original or convert to an aftermarket? I would like your input and if anyone has one for sale that would work I would love to hear from them.
Thanks

Why do you want a rear bar?

The answer to that question determines how to go about it.

A good reason is autocrossing: you want to be able to rotate the car more aggressively, and you've backed off the factory front bar significantly to induce oversteer, but still need more weight transfer to the outside rear tire.

There are three solutions: factory, inexpensive, expensive.

Factory is: get the factory mounts and have them welded on, and get yourself a factory thin bar. This works okay.

Inexpensive is: Weltmeister 22mm bar and their proprietary sway bar mount brackets that actually attach to the torsion tube.

Expensive, but the best: WEVO sway bar brackets (weld-on), SmartRacing rear bar, 27mm. But you should probably upgrade the rest of the suspension first. Check out their online catalog, it has a very good tuning guide.

I have Weltmeister front and rear bars and they are going in the trash barrel as soon as I can fit the Smart Bars into the budget. The Smart Bars have the correct kinematics, e.g. when you move the suspension through its working range with the torsion bars remove, they don't bind up. This is critical to achieving what you want with the bar, i.e. weight transfer from the overloaded outside front (pro-understeer) to the outside rear (pro-oversteer). If the bar binds up during the suspension's movement it just acts to stiffen the spring rate, and if the spring rate goes to zero, hello spin.
