To PolyBronze or not...

[DByers]

Magnus, Remember the WEVO setup is a complete system. So the price mark is not all that high considering you have new spring plates and WEVO's spring plate bushings. Now you just have to decide which camp you fall into in reagards to the spring plate bushing debate.

[Shaun @ Tru6]

I've got 20K hard miles on F/R polybronze on my 84 and have never had any trouble.

My shop, Rensport, has had to reinstall a few owner-installed sets.

Dan - Yes, and I bet it is a very good system, on a race car when doing a lot of suspension tuning.
I already got factory adjustable spring plates, not as easy maybe but I plan to set it and forget it.
Regarding which camp.... I was over at Gruppe B last night and read the forum and especially Souks posts, I get his point. I think I will get over there again and ask a few questions,, that are better asked in an independent forum.

Hmm, I think I´m going to trust Chuck that his improved PB bushings are going to work.

[randywebb]

can you repost his point for those not on gruppe B?

[DW SD]

If I did this again, I would buy the WEVO springplates. I do like the PB, but by the time you clean up the springplates, ship them out for powder coating or cad plating, do a fair amount of work to get everything aligned, I think the WEVO product would be good value. It is definitely more expensive as one piece, but time and money it saves cannot be forgotten. I had already bought my PB products when the WEVO products were released.

The engineering on their products seems to be absolutely first rate.

Magnus, I would hope you would ask those questions here as well. I still think this forum is independent and these are the subjects we can all learn about when questions about products are asked. I am no expert so I fall back to those who are and try and learn from them. I think Chuck (Elephant Racing) and Hayden (WEVO) both have a product that alot of people can benifit from using. I ended up with polygraphite for several reasons, $ were part of it but not the only reason.

Im hoping Souk adds his knowedge to this thread directly.

For those of you getting noise from your poly-bronze bushings, what kind of noise are you getting? I had them installed about six months ago and the back of my car is sounding like a young couple having a good time on a squeaky spring mattress. I just re-lubed my sway bar bushings, so that is why I am suspecting the PB bushings.

Thanks,

Won't happy Dan. If you or anyone else is interested in my opinion on anything technical, this matter or others, you can e-mail me directly or find my posts elsewhere.

[Jim Richards]

Bummer about what's lead Souk to that decision...he's been a valuable contributor to this board for the past 4 years. At least he can provide technical advice on the Gruppe B BBS.

[PorscheGuy79]

Constructive criticism sometimes lands differently on certain people's ears. It's a shame.

[MotoSook]

It's not exactly that Matt. I just posted my current frame of mind on this thread as I see Dan specifically mentioning my contribution.

SO! It is what it is...I'll just go drive my car

Tough to describe. More of a clicking sound than a squeek.

It took the advice of someone else to help me isolate my problem as the inner polybronze. With someone else pushing the back of the car up and down... reach to the polybronze with your fingers as the noise happens. I was literally able to isolate it to the inner bearing by 'feel'. fingers on the outer bearing... no vibration.... inner bearing.... felt the vibration clearly.

I also had completely removed my swaybars at one point trying to figure it out. still made the noise, thus it wasnt the swaybars.

Other things to check... trailing arm bushings and shocks?

Good luck.

[Chuck Moreland]

rickdm, it's alway good to ask the basics first. Are you sure you have Polybronze and not polyurethane or polygraphite? The names are similar, the products entirely different.

The later two are well known to squeak, Polybronze is not.

[rickdm]

Chuck, it is definitely your product that I had installed (the handling has been great), though it may very well be something else that is squeaking. I will try feeling around down there to see what I can isolate, and I will make another pass at greasing them.

thanks,
rickdm

One thing about Polybronze vs Wevo. If competiting Chuck's bushings will in most situations allow you to remain in "stock" class. Hayden's bumps you up to "modified".

Resurrecting this thread. Just ordered new PB's front and rear, plus larger torsion bars for my G50- 22/29. Definitely throwing the T-bars in, so since I'm there I was going to add the spring plate bearings and control arm bearings with Polybronze. I don't think I have much of a problem with oiling every once in a while...However lots of mixed views here on these vs. Netrix or stock OEM style rubber bearings. Mine is a weekend car only, and will eventually see the track once in a while. Trying to get the max out of the car while still retaining a streetable ride for weekends/Sunny days. She already has new turbo tie rods, new HD shocks/struts, ball joints and new control arm bearings for the front. Car is also lowered below euro spec. I think I'm all in going with the PB since i have them, but looking for any strong advocates for keeping it rubber all around to screw with my decision

10 years, some of these guys are not here anymore Go PB, keep them lubed, be happy.

[don gilbert]

Have had Chucks stuff on my car for yrs and many miles. Love the poly bronze. Your car must be straight. Put some on a buddys car that had been hit and repaired. Lots of extra work (for me).They must not bind, should flop like they are on hinges.

Haha oh man this is an old one. Be happy, best advice to date. Thanks Berk!

[Chuck Moreland]

Holy cow! 10.5 years. The internet is forever, I feel old, and time marches on.

We now have rubber bushings for those that want to restore stock ride quality and handling.

Polybronze remains an excellent high performance option.

And now we have Sphericals which deliver ultimate performance on a torsion bar car. Sphericals provide heim jointed action to accomodate chassis flex in operation without binding, and easily accomodates tweaked chassis.

all available from our host.

I look forward to posting in this thread in 2026 about our new magnetically isolated suspension bearings
