sway bar question

[tetuani]

Hello,
I have a 72 Nova project and I want to replace the stock sway bar, I want to order front full kit of PST.
I billd the car with 500 horsepower and for a daily driving. wich sway bar
Recommended?What diameter?
Sorry for the poor English and thank you in advance

You have to balance a sway bar with your springs and tires. What are your tire sizes and what springs do you have?

Also, welcome to the board!

Thank you for your help, I need to do more homework before I make a decision

Couple of things, PST uses poly bushings. Poly works great in things that dont have to articulate like sway bar bushings, but it binds in things like control arms. If you want your car to handle good, get a low profile tire, stiff spring, and small sway bar. The old school way is to have a tall sidewall tire, a soft(stock) spring and a big bar. A car with 235/40/17's and 800# springs would want way less bar than a car with 235/60/15's and 225# springs.

Unless they changed, PST use Polygraphite. Impregnated with graphite for lubrication purposes, but that will only work on the surface area around the bolt sleeve. The rest of the graphite will just be a filler in the bushing.

Regarding binding, in the Nova the only control arms are in the front. That being said, as long as the bushings are installed and checked for bind due to the bushing contacting the frame itself, these bushings will not cause bind. http://home.flash.net/~ivc1/cobra/frtpoly.html is a good link describing how a poly bushing should be installed/trimmed/lubricated.

Thank you both for your help I learned a lot.

I would use a 1" solid bar, or 1 1/8" hollow bar. Front coil rates used by many companies are around 600 lbs rate.

i didn't know this.
then why do some/most company's only offer 1?
i have a Hotchkis 1 1/8" Hollow Front bar on my wish list for my 70 nova, it's the only they list, they make is seem like one size fits all.

Youre right, poly is fine, I mean this noise really wouldn't bother me much:

That is goofy.
Either take the arms off and manually grease the bushings or install a zerk fitting and grease when checking on the balljoints/tierod ends.

I do agree - goofy. The way Pfadt does it which only applies to C6 arms, zerk is not reccomended. Their bushings are two piece which allow for removal and marine type grease on the cross shaft. I'll report back when mine gets on the road. Further note - spherical bushings cost a boatload and supposedly produce some noise, but not a lot. There is one guy that makes Delrin for C6, but he charges as much as the spericals. I researched this from the Corvette forums...

Edit: Sorry for the off sway bar topic comments!

Wow ... this movie scary.

They make one that matches their springs. The Hotchkis TVS kit with good street low profile tires will ride very well and still have great performance. Actually for a daily driver its hard to beat their kit.


Solid bushings are cheap, I can get them for $35 per bushing for AFCO's. I like acetal(aka Delrin) ones like Global West Del-a-Lum bushings. The GW bushings are the best out there bar none. They dont make any noise.

Great video!
I have a friend with a 69 Camaro that squeaks like that and it rides like it has super stiff springs, but they are stock.

The 1 1/8” hollow front bar is a great balance with the springs we offer for the Nova and Camaro.
