rear sway bar

Trying to get comparisons between the stock rear sway bar and a addco sway bay. I have a 79 AMX V8 with stock suspension. Any one think the addco bar would be better than stock. I know there both 3/4" diameter. One thing I don't like on the stock setup is the leaf spring isolators, but I can eliminate those. What are your guys thoughts on what may work better.  Thanks

I've done the Addco kit on several AMCs now, and here's what I've found works best. On 2-seat AMXs and Gremlins, the bar is a tad too stiff for my liking, but it is just right on Javelins/Hornets/Concords, which have a longer wheelbase. To correct the issue, Addco offered (and may still offer) what was called an 'adjustable end-link' kit, which replaces the center spacer tube with a spring or combination of springs, which collapse or extend as you enter a corner. What this does is slow-down the reaction time of the sway bar, so you have a moment to get the car settled into a turn before the bar takes full effect. What is really nice about the kit is that a bunch of different stiffness springs came with it, so you can tune the bite of the bar to your specific liking, or if changing from sticky autocross rubber to street rubber.

Every car is different and every driver is different. The stiffer sway bar can always be softened up (as said above) by replacing the center sleeves with springs. You can even use different spring pressures to find ones that work well with your car and your driving style. Or even use different durometer bushings to change the stiffness. In other words sway bars are tunable! Also keep in mind that over steer is way more controllable than under steer. In the words of the late great Dale Earnhardt "it's better to have a little over steer than any under steer"     

Right on Dennis.
