thanks,
Yes the 35mm studs are designed for those looking to do a stud conversion without spacers and without stud poke. The 35mm studs put the bullet nose of the stud just inside the wheel which means you maintain the factory look but the ends of the studs are far enough out to still make installing/removing nuts nice and easy.

The photo shows a conical nut/stud, but Porsche OEM is a rounded "ball" nut or bolt. These don't appear to be specific to Porsche, and will not fit the OEM wheels. If you are running after-market "tuner" wheels these might work, but anything made for Porsche and OEM fitment will not work with these.

Titanium exhaust part(not the exhaust manifold for sure,as Inconel still exists for this application).
I just mean that it is a question of correct titanium alloy and it is possible to make even titanium engine head studs(close to MP35N properties),what is popular in F1.

Anyway, if you want a deal, they are still new in the box, and I can ship them out to you tomorrow for $140 shipped in US ($41 off what I paid shipped).
Interested but your links are dead. PM me?

Used MSI on my Cayman R and they were great. Never an issue.
Have a set installed on the GT4 (still not home but probably Saturday).

I converted to these race studs from the lugs...couldn't be any happier.

Just put Rennline studs on my new Spyder. Never have figured why they went to bolts from studs. SO much easier to change wheels!

Are those the 35mm or 45mm studs? Look great!

Bolts are cheaper for a car manufacturer. I've had studs on my 3 street/track Caymans over the last decade and never had an issue. I once cross threaded and ruined a thread in stud which I replaced easily at the track. Try that with a press fit stud.

When doing a stud conversion on a car originally equipped with wheel bolts you have to have the shoulder there to stop the stud from threading right through the hub and sticking out the backside of the hub.
