Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Suggestion
If you're planning to go with 19" wheels without PASM, test drive a car configured that way before pulling the trigger.

would allow a better selection of OEM rims IMO since previous test drives had convinced me on 18" w/o

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.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1Original post

In yet another question aimed at helping me decide on options.... Are there long-term reliability and/or maintenance considerations when opting for PASM ? 1. Longevity (replacement interval) of PASM vs. non- PASM shocks. 2. Cost of replacing PASM vs. non- PASM shocks (parts & labor). 3. Known problems w/ PASM system. Although I prefer the initial cost vs. benefit of a PASM-equipped Cayman, I plan on owning my Cayman for a long while so keeping long-term reliability and maintenance costs under control is important. TIA

POST 2Original post

No known issues with PASM that I know of, and the system has been in use in Porsche production sports cars since the 997 came out in '05. I don't think much data is available on the logevity aspect,....but since PASM struts are more complicated with electrical interfaces, etc, I would only guess that since there is more to go wrong it might. Yes, PASM struts are more expensive. I forgot the last time someone looked the individual part prices up, but if I remember correctly each PASM strut was over $100 more than a non- PASM version,.....and those aren't exactly cheap, standard Porsche parts pricing applies here. So if you have all 4 PASM struts replaced, you could be looking at a $400 - $500 greater bill over a non- PASM replacement bill. Someone correct me on the pricing if I'm off base here!

POST 3Original post

Wow, that's better than I was expecting. Is that right? Well worth it if it's a $500 difference, IMO My advice: If you're planning to get 19" wheels, go for PASM - the car drives very harshly on the larger rims without PASM. If you're planning to go with 19" wheels without PASM, test drive a car configured that way before pulling the trigger. A teeth jarring ride will detract from every mile of the driving experience and enjoyment you get out of your Cayman.

POST 4Original post

Going with PASM would allow a better selection of OEM rims IMO since previous test drives had convinced me on 18" w/o PASM and 19" w/ PASM . Therefore, I would prefer PASM unless long-term reliability and/or maintenance cost was a significant issue, as stated in my original post. Thanks for the input Atlas !
