I would not use any rear sway bar with a 19mm front. The sixes are already tail happy and a rear bar would only accentuate that.

So I scored a 19mm front bar, wondering now about rear bars. This is for a fast road, touring event, ‘74 with a 3.2 build.

I like cars that are tidy in their handling but would prefer not to leave the road backwards...

Also looking to confirm that I can always address the real sway bar later because it’s bolt on that does not require any welding work?

Take me to school here please!

It also depends on what else you've done to the suspension. Remember, the suspension is a system, and is usually best approached as a system.

For instance, stiffer rear springs can give you rear roll rate instead of a rear sway bar. Likewise, larger front torsion bars can give you front roll rate instead of a larger front sway bar.

Tire sizes, alignment, and even driving style also play into things.

Thanks for the discussion and thoughts.

Looks like the safest bet right now is to install the brackets so they're there if I ever want to install a bar but leave a rear bar off for now and just drive her and see how she feels , yes?

i have a 20mm front bar 19mm torsion bars up front
140 pound rear springs and a stock sway bar. the rear sway bar makes the car more predictable for me on the street and easier to power over steer.

I like them, a lot of people don't. I run a stock rear bar on my car.

You can look at my car next time you see it. I have factory mounts as my car is an early '73 appearance group 914S model. (IMG:style_emoticons/default/beer.gif)

I welded the pickups on the consoles and firewall for adjustable struts too. I like having the rear sway bar, what's not to like?

Can you tell if you're lifting a wheel while driving, or do you need someone outside the car watching?
