#1 The ultimate setup IMHO is the ERP pro series which after selling off the RSS LCAs would cost about $2k and the most work to install end would endlessly confuse my alignment dude. He is OK with the RSS LCAs & bump steer toe links.

#2 The next option would be the Tarret tension/compression struts that would cost about $1.3K and be fairly easy to install after setting the lengths to match the stock pieces.

#3 The next option would be installing the stock arms that cost about $1.1K and again be fairly easy to install.

#3A The out of the box solution that I don't know how to implement would be to get spherical joints to fit in the stock arms since we both have hydraulic presses....has any one tried this ? http://cad.aurorabearing.com/viewite...led-ptfe-lined

In the front, I have 997 cup LCAs and thrust arms. In the rear, it's all stock except for the TPC toe arms. No changes are being made to the front. For the rear, I got the aluminum thrust arm bushings for the LCAs from TPC and I just ordered new OEM thrust arms.

I think that option #1 is the best. It's just a matter of cost. I don't think that there is much time to be shed on the track between your current setup and the ERP pro setup, but the ERP setup is definitely a more race car-like setup.

I am seriously considering these in the black version all around and possibly the front kit which allows for camber adjusting with the inner bushing.

That's a very good option as well. I would consider this for the stock LCA inner bushings.

Powerflex doesn't have bushings for thrust arms

Mihnea,
It looks like Powerflex doesn't have bushings for the thrust arms. They have bushings for everything else. I'll talk to them.

Rob

Ok. Please report back.

Contact with Powerflex, no joy: they don't have these bushings. My request was sent to the UK where their engineering is located.

Update: ECS doesn't sell just the bushings either

Check ebay, I think I saw the thrust arm bushings being sold by the UK branch. They ship to USA too.. I believe I also saw them on the Powerflex UK website as well.

OK I'll check that out

Intubator,
Thanks,I'll try looking there. The US Powerflex site didn't list them.

Rob

I have the OE arms I took off in case you want to experiment. 986, though...

No Joy on thrust arm bushes

No luck finding the bushings on UK Powerflex website or eBay.

http://www.powerflex.co.uk/black-ser...9+-2808/1.html I am looking for the other end of #2 in the website suspension diagram

I did find the TRW arms at Parts Geek for about $640 for two front and two rear arms. That is about $400 less than the Porsche arms that emanate from the same factory. Our cars may not be old enough to warrant development of these bushings?? Powerflex has every other kind of bushing imaginable but not for the Cayman thrust arms. If I get any word from Powerflex in the UK I will share it.

Sorry to lead you on a thrust bushing goose chase Rob VN...

Intubator,
No problem, searching is half the fun. I'm holding out for Powerflex to come through.
