I'm looking to add adjustability to my 997.2GTS setup and also eliminate much of the play/rubber bushings. Already done front Tarrett cup car LCAs. Looking to add F camber plates, F/R adjustable sways, F/R drop links, R toe links, R thrust arm bushing(solid).
I see availability from Tarrett, Elephant, TPC and some OEM parts.
Any considerations between vendors I should be aware of or are parts=parts at this level?
When choosing a suspension parts vendor, consider availability of setup support, and preferably the setup info is from first hand race winning experience of the particular model vehicle. That's how I choose vendors for my motorbikes.

My entire car is ERP or PMNA cup, with Tarett drop links. Many, many track days and have had absolutely no issues with these components. Monoball durability has been outstanding.
The longest version of the pin, referred to as a "trunnion pin" by Porsche Motorsport is made out of Vascomax C300 which is a high strength vacuum remelt steel alloy. Pretty trick stuff and undoubtedly used for it's superior strength and durably in a highly loaded suspension component. I highly doubt any of the imitation arms use anything more than regular steel pins. There is a lot more to these things than meets they eye and you generally get what you pay for.

Just got lazy...
As another point: Virtually all vendors will use something like Aurora or equiv for rod ends, Porsche usually uses Hirschmann which typically run ~$100 per, as opposed to $25-$50 per.
Some larger Porsche Dealers, there are a number of folks on this board who can get parts - you need to know what you want, I always provide the part numbers.
Just like Ray said, one of the big differences with the aftermarket parts are the junk FK or Aurora monoballs. They develop slop within a season or two, been there done that. I swapped all my suspension components to the factory RSR stuff about 4 years ago and it's as tight today as the day it went in. Well worth the money. Know your part numbers when ordering as there are absolutely no returns in the MS stuff! Lots of it is sold ala carte so you have to buy all the various pieces and assemble it your self, like toe arms for example.

This sounds all too tasty! How does one find a source for looking at some of these MS bits? Or do you need credentials
