Hello
I had the top Mounts replaced on My Porsche 996 c4s 2004.
I took the car to garage that had the correct machine to alter the tracking and the Camber.
Unfortunately the guy was unable to alter the Camber he spent an hour trying but was unable to correct it.
He has suggested that I may need to get the lower control arms replaced as well🔫. I was wondering if anyone else has had this issue or has any suggestions.
Thanks in advance

Is your car lowered? If it isn't, a good alignment shop should be able to get it back in spec assuming you don't have any other worn parts that would prevent the tech from getting/setting accurate alignment.

Did they at least give you a printout of the current alignment specs?

If your local PCA club has a site/forum, ask where the track guys go for their alignments. You should be able to find at least one Porsche indy with alignment chops...
The bonus is that you can ask them to set the car up for how you plan to drive, which can be fairly different from the factory specs. Some people want a more aggressive setup; others want to completely dial out negative camber because they drive like pansies and want their tires to last 60K miles...

It all depends on what the mechanic was trying to do and how much he knows about the model line.
One possibilities, outside of him being a dunce:
In a stock C4 suspension setup, it is very difficult to get any negative camber on the fronts. In order to do so, you may need to replace the LCA's with GT3 type, as they are adjustable to add negative camber. There are other Frankenstein ways to achieve it, but can require some custom machining.
If he was referring to material related to a C2, the front suspension architecture and adjustment points are different in a C4, which may have also caused an issue.

Any great alignment shop should have one of the latest Hunter alignment racks with laser alignment. If they don't and/if operator is not really knowledgeable about these cars as Macster eluded to, I'd find another more specialized alignment place. There's no reason why they can't get you back to specs, especially on stock suspension, assuming the car hasn't been in a previous accident. Did they at least give you a printout of the current alignment specs?

Hopefully that is the issue
