I was looking to improve handling on my 69 and saw PST polygraphite kits. Would this help it only cost a little more. Also looking to lower the car a little. Concerned with ruff ride. Any help would be great. Thanks

The PST super poly kit is well worth the money. I rebuilt the front end of 67 with one. The car is not done yet, but I have used their kits on my stock car. If money is not an issue, buy the super kit. My 2 cents worth.

Before I say anything, I am not discounting anyone's experience. I'm only relating *my* own personal experience.

I've had the polygraphite bushings in the a-arms of my 69 coupe for over 15 years now. Mine have done nothing but squeak and bind the arms since day one. Mine were the kind where the poly couldn't be removed from the outer shell for lubing before assembly. I realize things may have advanced alot in 15 years tho.

I'm getting ready to redo the front suspension of my car with the G-W Del-A-Lum bushings. I have these on another car of mine and I love em! My Camaro has stock shocks and springs with the polygraphite bushings. My 84 Cutlass has the 706# IROC springs with the G-W bushings and stiff Caprice police spec shocks. My Cutlass has alot more movement due to no a-arm bind. The Camaro would require alot of effort to get the arm to move before attaching the spindle. The Cutlass will move with very little effort.

As I said, that is only *my* own experience with them.

I just put them on my 68 about 5 weeks ago. Granted, the car keeps breaking, but I had no problems with the initial runs as far as squeaking or binding goes. I did not get the super kit, but it's probably a good idea. Also put on the PST coil springs, and cut 1 coil of each front spring. The ride is not as rough as you might think, but the handling is AWESOME. Check my web page, I've got a couple pics of putting this together, plus you can see how low it is from stock to taking 1 coil off.

Does anybody else have any input on this ?

I was also wondering about the squeak/crunch noises associated with the original "poly" bushings.

Are PST's Polygraphite bushings Quiet ?

If so , do they require periodic lubricating to keep them quiet ?

Are they molded like OEM bushings or do they pivot on the center sleeve ?

I am referring to the control arm bushings.

Thanks.....Billy

Cool

I agree with 69TPI383-
I had a PST super poly front end on my car that lasted only 11k miles!! They squeaked to high heaven, and i ended up replacing them with Global West Del-a-lum bushings. Best mod for handling next to the guldstrand relocation trick. Spend the extra cash now for the GW parts, they are guarenteed to last 100,000 miles.

I've had an entire energy polygraphite kit on my car for a couple of years, great stuff, not complaints, whatever you do don't buy rubber.

I put in the pst polygtaphite kit in my 67 along with their front & rear sway bar kit and kyb shocks. cut one coil off new GM springs. car handles very good and is dead quiet - zero squeaks. the low profile tires are what made mine ride "rough" but I like the feel.

Allow me to disagree with my brother, ChevyBoy 68's comment "Whatever you do don't buy rubber".

Here's some reasons rubber might be a good choice:

1) Easier on components.

2) Lasts a good while...I bet half of the firts gens still have the original rubber front end bushings (30+ years).

3) Smoother ride...it's like letting 10 lbs of pressure out of your tires compared to the poly.

4) Much less expensive

5) Don't squeek...and when they do, it's time to replace them. (I currently have a 69 with polygraphite a-arm busings that squeek like a pig in heat...also every rattle and interior squeek are much more noticeable with poly).

There are many as myself, who believe OE rubber bushings are the best choice. Yes, we give up some handling performance, but the trade-offs aren't worth it to us. My opinion.

thanks for all the info but I think I'm going with poly bushings and a 1.5 drop.

Sleepy-69,
I'm with you on this one.
You've taken the words from my mouth so I won't repeat what you wrote.

One thing that should be noted, it is not really a lot of use only replacing some areas of the car.
If you want to go poly, then replace all bushings, front and rear, including chassis mounts. Because the poly has less flex, it puts strains on other areas of the car, you shouldn't really go half and half.

For a great ride, well, as good as an early F body can deliver, then replace all this stuff with oem rubber. You won't be disappointed!!!

Have great Christmas "Team Camaro"

Any opinions on poly-graphite vs. Del-A-Lum?
