Hello all,

Last month, I purchased a 2009 GTS that was in good/great shape external and internal but it did need some mechanical fixes. It was really too good of a deal to pass up, and it was local, which meant no transportation fees or airline ticket and fuel home. It had way too many miles for me (122K) but I basically stole it, so I decided to veer from my normal route of buying the best example I could find and pampering it. This would be a real test of buying something that I could beat on a little bit and then fight my strong urge to bring it all the way back to showroom condition. I realize now I should have possibly started a thread outlining the repairs & updates I've done. After having it PPI'd, I knew it needed some work. New HPFP, both fuel pumps/filter, plugs, drive shaft, fixing air leak, fluid changes on both axles, transfer case, transmission fluid/filter, etc., I'm into the car for about $12K with the knowledge that all the major failure points are now new.

That's the long way around of getting my original point of the post. So the car has some light suspension chatter going over uneven bumps and I MUST fix it. During a check at the mechanic today, all felt fine except the sway bar end links. They have some play and it was suggested that we start there. I was thinking that if I need to change them, I might as well look to upgrade them. I was searching for polyurethane sway bar links, but I don't think they exist. Then I thought about buying a poly kit and pushing out the existing bushings and refitting them with the poly bushings. I would also probably want to change the other two bushings (attached to the frame) on the bar as well, while I'm at it.

In short, has anyone done this? I see the end links for the PDCC cars appear to be much more beefy. Could I use those in place of the original? II searched but don't see anything specific to my line of questioning. I see many places to buy standard replacements but I think I would rather put in some poly. I see that Powerflex has a kit to swap over to poly. Or, has anyone done this already and would recommend against it?

Any enlightenment would help as I want to get some parts ordered soon and tackle this in the next week or two. BTW, here she is...



Thanks!

BTW, I'm looking to change these out myself. It doesn't look too difficult. Is that true? Now that we have some time, it's great to spend some quality time with the Pcar in the garage. Wife is a little jealous... As for the power steer hose leak? That supply link looks like it's a PITA to handle and with the fluid drain that has to happen, that's a quick decision for the mechanic to handle!

Cheers

 

I'm using the poly end links but PRG has a better option. The chatter is probably upper strut mounts.

@J, Thanks for the link. Those look really nice. Did they make a difference in the handling? I originally thought it was strut mounts or perhaps some loose bolts but the mechanic said all appeared tight and would start with the sway bar links. Perhaps because they were cheapest before digging into the more expensive stuff...

 

@J'sWorld It appears that the PRG links would probably be adjustable enough for P!Gs with PDCC. The links for the conventional sway bar are different from the PDCC ones. I should measure the length of mine with PDCC and we can compare to non-PDCC.

 

Sounds good and just to clarify I am running the poly bushings in factory links on a 955. I just thought the PRG links looked nice.

 

The PRG links do indeed look very nice. I wonder if they are a little bit of overkill on a P!G... on one of my former 911s, they would be right at home. I wonder if the ride quality would suffer much with the Heim links?

 

you're overthinking this too much. OEM lemfoerders or equivalent will last another 100K miles, and they're pretty inexpensive. Besides, you don't even know if the new sway bar links will fix your suspension noise, as it could be something else.

 

@Petrolhead, I agree. However, if I have to change them anyway and there is an agreed upon upgrade, I would kick myself for not knowing about it. After going back and forth, I just ordered a set of poly bushings from Powerflex USA. I'll pull the end links, press out & swap in the poly bushings and re-install the links. I'm always looking for an improvement in ride quality and cornering over stock, plus I'll never have to worry about the bushings again.

Cheers

 

That's the direction that I am headed- poly bushings and forget it. I think the PRG links would be overkill for my purposes. With the Heim joints, they may introduce new noises to the mix, so poly it is!

 

I just installed mevotech supreme links from rockauto. We had some front end noise as well but I believe it was mostly from the failed lower control arm bushing. We used the aluminum mevotech supreme option on rockauto as well.

 

@957GT-YES @TomF How did go with the powerflex bushing upgrade? I am considering getting a set as I am about to swap the lower control arms. Anyone else upgraded with feedback?

 

@J'sWorld How do you like it? Looking at the pricing, the Powerflex bushings are about $128 shipped to me (plus I need someone with press to swap them out) vs the PRG units $162 shipped and just plug-n-play. Looks like equal deal pricewise to me.

 

They work great and you wold need a press at least to remove the old bushings. Honestly for the money and ease I would do the PRG with the added benefit that they may have more free range of motion.

 

Thank you, I am leaning towards that.
