Some yes, some no. Mine, no.

This is usually where someone calls me an idiot (or some equivalent) because I have the original IMS bearing AND an unbalanced LWFW! Its a timebomb!



But it has 136,000 miles and 85 track days without a hitch. So far, so good.

I don't think this is an exercise in personal attacks, but a sharing of some hard learned information. You have had good luck, and that is a good thing. But others have not been so lucky, and some have experienced a disaster. Given the inconsistency in how these units seem to perform, I think it is a good idea that others be aware of it, particularly if they are paying someone to do the installation.

We do not do lightweight installations based upon our direct experience, that of other shops, and of course what Jake has seen. Porsche even released a dealer warning about the use of "single mass" flywheels, indicating that any damage would not be covered under warranty if the car still had one.
