Just wondering what's the story with the stock tie rod design, the one with the rubber donut for an inner tie rod end. Porsche kept it in production for about 25 years (through '89), and then the 964 used the same approach, except reversed it with the yoke on the rack and the rubber donut on the tie rod. I've read a lot of testimonials for the turbo tie rod, but if it was that much better, why didn't Porsche convert over across the board? It couldn't have been cost- every econo-box I've ever looked at has ball type joints at both ends.

Maybe it was to add a bit of dampening? They used to sell steering dampeners for cars with light front ends (Corvair, VW, 356).

Maybe a bit of shock absorption to protect the rack from hard hits, like pot holes?

And while we're on the subject, I saw in PET that the 930 that first had the turbo tie rods had a different rack. Anyone know the difference?
