Has anyone confirmed that the 991 GT3 version is the one for the GT4? I'd hate to order and then find that Centerlocks vs. wheel studs creates an offset issue (I can't see it, but better safe than sorry).
Also, any Tarret discount codes floating around? Or maybe group buy?
=====================================
EDIT: The group buy is a go and we've had over 30 people express interest. Head on over to the group buy page and place your orders (pricing information is there). Once they have 20 confirmed orders, they'll start shipping. It should run for 3 weeks. Thanks to all for making this possible.
2nd EDIT: Studs have been installed on a GT4 and are confirmed the correct size (62 mm front/85 mm rear)
3rd EDIT: Install guide (with lots of pictures) now available

I was talking to the GT tech at my dealership about these studs and he mentioned that there is also a hard line to the calipers that you have to deal with when changing pads. Wasn't somebody offering a braided SS line to deal with this?

Yes and no. I talked to orthojoe on here and he confirmed that the attached pic is a rough approximation of his GT3. And as we know the GT4 brakes are based on it. The short hard line (item 8) goes to a bracket (item 6) and from there it is flex line (item 5). The bracket needs to be removed from its mounting point in order to move the caliper.
In regards to the SS brake lines Clark at ApexPerformance, a sponsor on here, sells some or you can contact your dealer for a solution.

Who is your dealer?
Do we know for sure that the SS lines obviate the need for the bracket to simplify caliper removal? This stud and nut kit would still be worth it on its own to avoid one-time bolts and upright thread wear, but SS lines further simplifying caliper removal would be great, seeing as Porsche inexplicably removed the bridge to allow quick pad swaps on the front calipers.

If you look at the dashed lines you will see different connections at each end of the hard and flex lines. All the SS lines I've seen replace the flex lines only. And both front and rear calipers use the same tech.
Studs will help a ton. It's really easy to cross thread the bolts, especially when you are changing when whole assembly is really hot.
Agree - I upgraded to studs on my Evo (6 piston Brembo kit) and it's a big improvement. But someone needs to offer a solution to remove that bracket issue!

Used them on my 981CS only way to go if your going to be switching pads for track. It's amazing how much more difficult they made a simple job. It used to take longer to R&R the wheels than to switch pads.now it's a 1.5 hr job! Carl
