Fitted New Cayenne Calipers on UrS6.

Also i have done a little weight test ....

Yes but how much of that weight loss was added back by the larger rotors? It might shock you to know.

Dear friends ,


I just installed this setup. It was really plug&play


A bottle of "palinca" to Popdemonic !

[UrS6 - IamS6]

Did bought HEL's Golf mk2 to Brembo braided hose kit. They seems to be 450mm in lenght with a nice 90 degree elbow on the caliper side. Hope they will be good...

Photos when you are ready.

Thanks.

Thomas,
i believe you could use stock brake hoses if the length
is enough when turning the wheel lock to lock.fortunately,
i have a pair of old SS goodridge from a nissan 350z.i had them on
urs6 and worked well.

This is the wheel bearing housing that Pop has on his UrS6 in Thailand.

Not disputing that. Just stating that the bolt centre for the 18Z caliper or Cayenne/Panamera is 146mm. He posted 130mm.

C4 UrS Wheel Bearing Housing and Front Brake info

I have HP2 struts and any Porsche big chassis with axial(side) mounts is bolt right up.

Issam/Wizard: In case you didn't know this, all the Canadian/US C4 UrS4/S6s got Girling G60 front brakes on "special" wheel bearing housings. In the rest-of-the-World (ROW), the UrS4s started out with "UFO" front brakes on unique wheel bearing housings. By some time in 1993 model year, there was a switch to the "HP2" calipers on yet again a third C4 UrS wheel bearing housing, not found in NAmerica (unless specially imported as a part). The HP2 brakes and their associated wheel bearing housings were then used on the 94 UrS4s and the 95-97 UrS6s in the ROW. This is the wheel bearing housing that Pop has on his UrS6 in Thailand.

Great write up!

This part is a little confusing. These are
Porsche Panamera / late Cayenne Turbo S calipers (4.8 V8 NOT 4.5 V8 which came with the 19Z's). They are larger than 18Z's so not exactly the same.

These are the part #'s
955-351-421-70
955-351-422-70


Not without adapters.Both 18Z & 19Z use a 146mm Centre to Centre on the axial mount
Same goes for B8 S4/S5/RS4/RS5 so if your C6 has a 146mm centre to centre then you can use them.

Yes the calipers were taken from 957 Cayenne 4,8 V8...

Thanks for the correction.maybe i'm confused between the number from Porsche PCD which has 5x130mm. I have HP2 struts and any Porsche big chassis with axial(side) mounts is bolt right up.

1.18ZR/ZL from 955 Cayenne S or Turbo.only differences between these caliper is finished color..

George,
you need to try to measure the caliper mouting distance on the strut if yours is 130mm IIRC.if yes,you probably can fit 18zr calipers.

Gents I wonder if you can confirm if the 18z calipers will fit straight onto my C6 A6 3.0tdi avant.
My current disc size is 347 x 30mm. Do I bolt them onto my existing carriers or straight onto the hub?
If not a "plug n play" unit, what mods are needed to make them fit?
Is it best to get the larger disc or can I stay with existing disc?

Sorry for all the questions for my first post, but I hope this will make the braking better.

Thanks
George

That just some picture I took from the internet, they will look kinda like that but bigger and more robust.

[dustovich]

Those look a lot more robust then the american versions , especially with that reservoir. Sorry to hijack.

HP2 euro style...

[dustovich]

What strut cartridges do you have?
