Thanks Haz -

I was prepared to do the upgrade with any S i bought but have been surprised how many shops are advising against it.

All have said to do it if you are doing the clutch and want to for peace of mind then have it done. But when techs and shop owners who stand to make $$ on every one they replace are saying no need to do it...

One reputable Porsche shop Master tech in Washington State said " we do not believe in stressing an engine with a IMS bearing replacement for fear of what might happen.
only week one with the car and lots to contemplate.

Thanks again to all ...

I don't know much about the 986 yet or engine internals in general, but I don't understand this statement at all. Hopefully someone with more experience will address this comment

After a week of ownership, I ordered then hours later canceled the IMS Guardian. Instead I I decided to spend the extra money to have the bearing replaced. Peace of mind is worth a lot to me at this point in life.

That statement goes against every but of information and experience I have on the IMSB to this day. All I can imagine is that they might not have gotten many jobs in with the issue, but that does not change the fact that IMS failures are happening on a daily basis now.

Might it be that they don't actually don't perform this job? Not every Porsche Center do this and the IMS bearing is not something Porsche offers as a "loose part" for you to buy, as it is a smaller part of something bigger.
That is why LN Engeneering created it as a loose product.

I strongly recommend the upgrade. At least get a quote for the upgrade. Please.
