I am thinking about changing the coffin and control arms on the 2002 targa, I dont have knocking but the ones on the car do seem to be original, the car tramlines quite badly, the geo was done when i got the car last year and I am about to put a full set of new boots on......

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.
15 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

Evening all, I have searched and many suggestions appear to be a few years old so thought it worth asking again.
I am thinking about changing the coffin and control arms on the 2002 targa, I dont have knocking but the ones on the car do seem to be original, the car tramlines quite badly, the geo was done when i got the car last year and I am about to put a full set of new boots on...... so it seems a good time to do this!
I have found, through searching online, several options, but am lost which ones are best to go for. Car is not tracked and i am not bothered about making it handle like a go kart!
What are your recommendations! (and suggested place to get from!)
Thanks
Chris
You would change the coffin arms for 3 reasons ..
1/ The bush in them is debonding , the diagonal arm attatches to this and if its excessive debonding .. 50 % i belive then its an mot fail .
2/ The ball joint has worn and there is play so again an mot fail or the boot has split .
3/ The locateing bolt is seized and you cant adjust the geo to get it in spec , you will need a bolt as well in this case .
Diagonal arms are changed because they knock .. there is no play but it is annoying and Not an mot fail .
If none of the above apply then there is no point in changeing them.
Tram line is down to geo and tyres , thrust angle imho ... ill also add tyre pressures .
Were to get them .. ECP would be a good start .. after that google .
Hartech do a good line in re-furbed arms, they're based on genuine arms so you don't get the potential geo issues that a certain batch of Meyle ones had, for example.
Good prices - a set has been running for two years on my car..
Thanks for the replies, there is a "small" amount of play in the front ball joints and signs the bushes have split slightly (but no play (garage words!) and, with them appearing original, I just didnt expect them to be in good condition! Do these things last more than 100k miles?
Have just bought a bunch of Meyle control arms, diagonals, drop links etc. They were recommended to me by a good source, look very good quality to me!
Good price and fast delivery here:

Same here, one of my car's rear coffin arms is delaminating, so I've ordered Spyder parts (tuning forks too), and Center Gravity will fit and do a new geo for me.
Dont forget to wax them! CG use Wurth underbody wax on them. It is ally corrosion tracking under the rubber that causes delamination of the bush. Only began appearing when Porsche stopped waxing them from new according to CG.

Agree grease/aluminium anti seize/ copper slip on the bolt shaft, but to clarify not on the thread as it leads to incorrect torquing. There are special products for that I think.
in my case, I coated the bolt shaft and then after I torqued the nuts, I covered them and everything in the wheel arch in liberal amounts of bilt hamber dynax.
This is a source reference. Confirm exact model applicability in the original material.
