Default Tie Rod "Ball Joint" Taper?

Does anyone know what the taper is on the ball joint studs used for the front and rear toe links in a 996/997 cup?

Yep - or buy them very cheaply :-)

I am in process of having some direct factory replacement rod pins manufactured, so stay tuned on that front. I am also designing up the rear toe links from the cup S/ RSR / 997.2 to be able to provide great pricing on those as well. (the

Thanks

Perhaps an option that allows for Hirschmann beaings would work?

If you can find a retailer for them I am all in. Only way is through Porsche or to be a big player (like Porsche) that I can see.

I purchased rod ends straight from Hirschmann USA? Prices were better that PMNA at the time, NHBB has some nice rod ends as well.
