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.

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 1Original post

There's enough room in the front of Porsches to add a multi link suspension. Is it because of weight? These are high end cars, surely it can't be cost. Why not wishbones?

POST 2Original post

According to my understanding, saving space and cost. Wishbones, or Short-Long Arm as it's sometimes called, requires more sheer width to get the geometry right. Also, getting SLAs to have competitive weight generally drives you to aluminum components, and that's costly. The 911 does use a multi-link design in the rear.

POST 3Original post

It's about packaging. While double-wishbones could be made to fit in the front, the upper ones would cause the front trunk to be narrower. While it's not technically the best for performance, I'm happy with the current set-up. These are street cars, and one of the nice things is that, with the large trunks, they're practical.
