So what is your plan?

I'm in for a group buy of the adapters and spacers. Need to pace myself on the rotors and calipers.

And thanks for paying attention to my red-headed stepchild.

And these......

Can anyone post the front brake line length and hard-line fitting size?

It's the last piece to the puzzle... (part #1)

Wonder if one of the companies doing the braided stainless could make up the hoses easily ????

I made up my own inexpensive hoses plenty of times. I used M10 x 1.0 "bubble flare" (Porsche) to -3AN.....then -3AN to 1/8-27 NPT fitting (Wilwood)

Just use proper length DOT SS Braided -3AN lines....big improvement over the factory rubber lines.

i estimate the hose length at 13.5"-14" running a flexible tape along the existing hose. this does not include amount of thread engaged at each end.

Where's the fitting on the caliper and what type is that? Later S brakes take a banjo fitting there and I like the way that works.

Coming in here late, great work XSChop!

I will be down for a set of these when they are ready, much better then doing a full suspension swap or swapping spindles.

100% Bolt-ON and just got this pic (Cup-17's). I'm becoming more and more optimistic about the 16" Phonies..... What is the Front ET of the 928S wheels?

with the S4 going to big brakes, as many know, i was able to just use spacers to use the GTS 322mm rotors. almost the same as the 330mm rotors, but it would be real nice to be able to adapt even my S4 to the 350mm rotors! 14" is what all the racers are going to and for good reason. is there a way to get an adapter made to do axial to axial position change wile also changing the offset a little??

The Cup-17's are 55et so that's more good news. Thanks for that link.

As for S4 brakes, I thought those were 130mm RADIAL mount Spindles/Calps?
The trick to going bigger on radial mounts is using the exact offset rotor with larger diameter and the Cayenne 350 rotors are the same offset as the 330 rotors and the hub interface is machined the same so the centering rings can swap over.

That looks really nice. One could paint those calipers red or black and use one of Nicole's stencils for a factory look. Is there a Wilwood caliper that would work on the rear as well?

There will be. I think the S4 rears are the exact same 300mm rotors as the 951's and the mounts are 94mm C2C too.

Looks very good!
The problem is German TÜV don´t like technical changes on the brake system!
