Fitted New Cayenne Calipers on UrS6.

[Wrath]

lol Thuppu can fabricate everything!! what is the C6 Disc size anyway?
Thanks,
pop

Looks so not Corvette discs but --> "347X30mm Rotors from A6 C6 4,2model"

[popdemonic]

as my write up i believe you can directly fit them on HP2 strut.it needs 16mm bushings and 17ZR pads.

[Wrath]

Sounds great, but I still haveing trouble finding calipers in right price range, don´t want to pay 600 euros for used ones... still looking...

@ Popdemonic. I am doing this Cayenne caliper brake upgrade on my UrS6 using the UFO brake style hub carrier sourced from an Audi V8.

The North American vehicles never did get the HP2 brakes but the bolt hole spacing for mounting the caliper is the same for both hub carriers. On the V8 hub carriers,the caliper mounting bolt holes are sized for a 12mm bolt but I can enlarge them safely to 14mm. I am using the A6 rotor sized at 347mm & the 18z pads contact the rotor right to the inner & outer edges of the rotor face. Can you provide a picture of the bushings that mount the Cayenne caliper to the HP2 strut? I am not able to mount the caliper flush to the ears of the UFO brake style hub carrier. Looks like I need about a 20mm spacer for this to work.
Thanks, Chris

Hi Pop,

Just re-reading this thread, can I ask in simple terms why you changed from the orange calipers to the silver calipers ?

Was it to with the disc / rim sizes ?

Orange / 360mm / 19" rims

Or

Silver / 350mm / 18" rims

???

Can you advise what car the big red banana shaped brake calipers are from ?

Thanks.

[popdemonic]

I rezized the disc by machining it down
From the 360mm to 354mm IIRC since
physically ,the silver calipers is smaller
And narrower on the neck(will be touching
The rotor edge when you fitted the caliper on
the rotor).i sold the orange calipers to my friend
And also want to try if the silver's is just also bolt
Right up on HP2's struts.personally i think the
Orange calipers is most straightfoward and easily
Set all the things up on our car.the silver calipers
was taken from 955 cayenne S 4.5L and
The orange banana shape cailper was taken from
2007-2010 957 cayenne 4.8L.i believe it's also identical
To latest 958 cayenne and Panamera.

the issue is you have the UFO struts.the differences between the HP2 Struts and UFO's the mounting distance from ear to ear.HP2 has 130mm on mounting distance
which's the same as Cayenne calipers.the Calipers can directly be mounting on the
HP2's.you just need the 16mm bushing (spacer)to hold the calipers set right up on the center alignment with the A8 discs(360mm).these rotors has the same overall
height as 314X30mm UrS6,323X30mm A8(D2) Discs.

If you're going to fit these calipers,i think you might need larger disc to provide the space for the customs bracket to be mounted between the strut ears and Calipers ears.like this...


let me know if you need any inputs.
Pop.

The UFO hub carriers have the same bolt spacing as the Cayenne calipers. I am using the A6 4.2 disc @ 350mm to do a mock up test fit but will probably use the larger 360mm disc & cut it down to 354-355mm. I will post pics when I can.

Pop,

Will the orange banana shaped caliper fit underneath an 18" rim, such as a Mk 1 S8 rim using spacers on a urS6 ? And if so, then one should use a 360mm disc, cut down on a lathe to say 355mm or 350mm ?



The above discussion is about an urS6, but can I ask the following re a B4 S2.

Does the orange banana caliper bolt straight onto a B4 ABY S2 strut or does one need a custom bracket ?

Thanks.

[popdemonic]

you need 360mm with banana style calipers and yes it fitted perfectly under 18's

[popdemonic]

if you use the banana calipers,you can remove the stock calipers bracket.it's radial mount style calipers.

[Thuppu]

I did read this thread ones again. Touareg/Cayenne Z18 6-pot calipers on a UFO strut. What disc is the easiest to use? A8 34x360mm? It must fit under 18" wheels. Is there any combo that fit under 17"? I didn't see any clear answer to these questions...

[popdemonic]

Thomas,
i have no idea on the ufo struts if you can find the solution to bolt
the 18zr calipers right up on the strut w/o any brackets.it should fit
under 18" though with the inner step 18" rims ie,BBS LM.
remember once you use this calipers the easiest way to make everything
simple based on HP2 struts is grind off the overall disc diameter down from
360 to 354mm and use the 17zr brake pads and you are good to go.
as i stated on the thread i need to fabricate the 16mm bolt spacers to make
the calipers sit on the center alignment of the disc.remember here's based on
hp2 struts not ufo's.

[popdemonic]

one thing,in order to running the calipers under 17" rims.you might need
17zr calipers Thomas as the 17zr has a shorter arm on the calipers(for a smaller discs)
let's say Cayenne V6 has 17zr with 330mm while 18zr has 350mm disc.the
problem is we could not mods the axial mount style caliper just like the
radial mount style caliper ie,f50,boxster calipers.the calipers arm will
identify the required the disc diameter and we just sort the correct disc size.by doing
this,i needed to resize the disc down from 360 to something like 352-354mm.
if you want to run a smaller disc(to fit under 17" rims) you probably need 17zr
from a V6 cayenne not 18zr.i believe 330mm disc is a way to go...
ps.17zr and 18zr is identical except the longer vs shorter mounting
arms on calipers.the brake pads is interchangeable.i'm running 17zr
brake pads on 18zr calipers due to the sliding face of the disc being
narrower by grinding off the outer edge to resize it down.

[Thuppu]

I have an extra pair of UFO struts that I will modify to coilovers and fit these brakes. Have to measure the space before I order discs, the 347x30 could also be a choice, and propably quite lighter. These calipers are from an VW Touareg and I did buy 4-pot rear calipers as well. Will propably try to fit them on my A8/Phaeton 310x22 discs.
