One further query, if I replace the 'coffin' arm, do I need to get four wheel alignment done?

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.

POST 1 / ORIGINAL POSTEROriginal post

Hi all I've got a 2003 996 C2 convertible, I need to replace the front track control arms and understand that there are both adjustable and non-adjustable. How do I know which I've got? It was in for an MOT at Porsche on Friday (who failed it on the n/s track control arm) and they said it was adjustable, but I'm not convinced; why would it have adjustable on a standard C2? How can I identify which it is? Many thanks Chris

POST 2Original post

The adjustable coffin arms fitted to a GT3 come in 2 Half's with shims between to give the adjustment in camber. The usual arms fitted to other cars are a single casting piece.

POST 3 / ORIGINAL POSTEROriginal post

OK, thanks for your reply, so you'd be able to tell visually from looking underneath? I'm fairly confident that it's a single casting. It confirms that I should never believe what main dealers (generally of any brand) tell me. The guy who called me was adamant that they were adjustable. I'm assuming these wouldn't have been fitted as standard on a C2? One further query, if I replace the 'coffin' arm, do I need to get four wheel alignment done? Thanks Chris

POST 4Original post

Stock look GT3 style Camber is adjustable on the stock arms via an offset bolt at the fixing point to the chassis, so technically, they are 'adjustable".

POST 5 / ORIGINAL POSTEROriginal post

Brilliant, many thanks. :thumbs:

POST 6Original post

I think by 'track control arms" your Porsche man means track rod end. This is the end of the steering arm. These are adjustable on all cars for toe in / toe out. If so he's not lying to you!

POST 7Original post

There is a second type of OE adjustable arm. Porsche did an arm with an adjustable castor bush in it (the centre bush for tuning fork). These were widely available at one time, but have since become very rare. It is otherwise a standard fixed length arm, but has the adjustable castor bush fitted. It maybe that you have this type of arm fitted.

This is a source reference. Confirm exact model applicability in the original material.
