It missing the rear sway bar end links and the front and rear sway bar bushings.

Rather than just replacing the bushings in the original rear control arms and panhard bar i would just go aftermarket. The factory stuff is so flimsy i could bend it together with my hands. UMI has good sales from time to time (memorial day sale maybe?) where you can pick up a rear end suspension kit for under 200. Yes its a bit more than just buying the rubber but you get what you pay for.

As for what all poly will do for you...you WILL notice a difference. I have full poly in my car except for my motor mounts and it really is damn stiff.

Thanks very much for your obsevation. I'm in a tight budget so I'm doing thins one at a time and the bushing replacement is one of them. ofcouurse I will replace some suspention parts eventually like the rear an subframe conectors and the traction bar that connect to the transmition but I can't do it all together and I think to start with the bushing and are deciding eather to buy a Kit or just what I'm goin to use separated.

What do you think?

If you plan on changing the parts later save some money and just replace whats bad with stock rubber stuff from the parts house. Hell it lasted 25 years new stuff will last a long time also.

All my back stuff has rod ends and my front a-arms have Del-A-Lum bushings. IN other words the only ones left on my car are the ones for my sway bars and they are greeseable brackets with polly bushings and polly end links.

That kit basically has nothing for my car that was why I noticed the sway-bar stuff missing.

All rod ends here too, even the torque arm.
Poly front and the same sway bar stuff as yours.

This might present the perfect opportunity to install the Energy Suspension motor mounts.

Thank you all for the info. Insted of buying the Kitt I'll probably by them separate and change them as I buy them so I don't spend in parts I'll probably replace later any way

As may have been noted, different years / models had different size sway bar bushings...
And there were 2 different torque arm bushings too...
For $200 or so you can get aftermarket lower control arms and panhard bar, you will notice a difference... if you're keeping stock height, get non adjustable ones, but if you car is lowered (or raised I guess), get the adjustable ones, a bit more... Do a little bit at a time... I started with a stock 91 Formula, and a step at a time, improved the suspension... and it is day and night difference from now and where it started....

I hope you like squeaks and vibrations!

They will definitely stiffen up your ride, but I would avoid these:

Aftermarket rear LCA's are only used if you need to re-center your wheels. I run the stock LCA's on my 11 second TTA. I've read articles showing the stock with the rubber grommets are better because they allow some give. With poly, you are risking tweaking the "frame" where they mount, or twisting the brackets on your rear. I do have UMI's on my GTA and they squeak no matter how you lube them.

I would never put poly motor/trans mounts on a car unless it was track only. The potential vibrations may drive you crazy. You won't rip out rubber mounts unless you are launching 500HP on slicks. There are no "performance" gains to be had.

Just my opinion but I've owned several thirdgens with almost every mod available so I am speaking from real experience.

The only reason I mentioned replacing the motor mounts with Energy Suspension polyurethane is because if hes has to remove the lower control arm to install the new bushings than that is the time to replace them. If he wants to stay with rubber than its still a good idea. I replaced mine with new poly. made buy Energy Suspension because I had read that they had some give to them as opposed to the Prothane brand that were hard as rocks.Any way I replaced mine by myself with out removing the arms and it was a nightmare. Another reason to replace them with poly.. I don't want to have to do that again for a very long time. If your car rides like a Cadillac and you want it to stay that way than you might want to skip the poly. mounts but if you don't mind the slight vibration created by the engine,that feels like a muscle car should than as I said skip them and use rubber.(its a slight thumping vibration not a buzz type)
As mentioned above I also would keep the rubber transmission mounts .That seems to be the spot where the "major" vibration can sometimes come from.

DO you have a link to any of the articles. I would love to read them.

No one on this forum has complained about that that I know of. Even so it would be a HP problem not a part problem. If your pushing 1,000 HP yea some extra bracing would be in order.

Also I think he decided to go with rubber to save money for now.

Went under my car this Weekend and found out I already Have:
1. Rear Lower control Arms By Hotchkis
2. The Bar that locate the Diff by Hotchkis

I felt like I just got a present

For the bad side:
1. The end link are completely gone front And Rear
2. The Front Mounts are crack (Rear Look Good)
3. The rubber for the traction Bar look that will need to be replace soon
4. The Swey bars have rust on them
2. The Front Lower Control Arm Bushing are crack

So I'm goin to start by changing the end links with the mounts clean and paint tha bars. Anny sugestion on the rubber?

would thes be good? (http://www.autozone.com/autozone/par...64_432492_5611_)

Did you get anything done on it?
I went with all PST in a kit for my car, including the motor mounts. No problems no complaints.

^^^This.

I had Spohn Poly LCAs on my car for 5 years, and BOTH of my LCA boxes ended up bending out of square. I replaced them with stock control arms and GM 1LE bushings. I don't get the hype for poly and tubular suspension parts. if they stock parts were good enough for SCCA, why are they terrible now?

Dakota W.

The only time you should use poly bushings on the rear of the car is in drag racing, where you actually need it. If you're doing autocross or daily driving hard and going around corners fast, the polyurethane will bind. The binding is what you're referring to. rear LCA's aren't for re-centering your wheels, LCA Relocation Brackets(LCARB), and adjustable panhard bars are. Aftermarket LCA's are stronger than the factory LCA's and add rigidity, but shouldn't be used with poly bushings because the polyurethane binds.

And to the OP, you'll need more than just that kit to replace all the bushings with poly. But I wouldn't put poly on the rear of the car anywhere, just get new rubber bushings.

carattini

Thanks for all the advice I'll let you know when i do somthing about it. I think I'm going to start with the swey bar bushings and end links since the are gone.
