17z calipers.

[Davdraco1]

I've been looking into doing this BBK and in my searches I've found calipers from partsgeek: http://www.partsgeek.com/gbproducts/...FQQSHwodaAwASg

I guess technically they are A1 Cardone. What's the difference?

[pbcrazy]

A1 Cardone is just the company that reman'd them

[boomtime]

A1 cardone is a remanufacturing company they replace the seals and slides and hot tank the parts.

[Davdraco1]

But they are real 17z calipers then? I just don't see why more people aren't doing these then. 103$ bucks a side....

[Seerlah]

People do, piece together full kits and resell them for around the $700 mark. They do the same thing. 6 pot calipers is a 6 pot caliper. What makes the huge impact of brakes being better than others is hardware, piston size, rotors, lines and pads.

[k0mpresd]

+$50 core charge per caliper. so $153/each in the end.
i pieced together the kit on my mk6. about $500 total.

[Davdraco1]

Still on hell of an upgrade. Any other BBK from stop tech or alike is well over 1k. To do the swap you just need S4 uprights and a mounting kit with 2 mm washers right? Also, what rotors are needed? I've read C230 sports work but you have to make the holes bigger?

[Seerlah]

Not even. They have bracket kits out there with hardware for our uprights. Pricey, but it is what it is.

Is there any advantage to S4 uprights over those bracket's for the a4 uprights? Definitely something I'm considering

The bigger advantage is if you can find the aluminum uprights. There is a huge difference in weight between these and the cast versions. These are available on some S4 and many C5 A6 models.

[ray4624]

if you have an 01 the way to do it is with s4 uprights.
All other years it is cheaper and easier to just get the brackets.

[Davdraco1]

I think the 01 can keep the same axles right?

[ray4624]

indeed

[MetalMan]

Yes. '01 1.8T got the 82mm bearing upgrade, whereas '96-'00 1.8T came with 75mm bearing. S4 uses 82mm bearing, as do the V6 models.

That's definitely good to know. C5 A6's shared uprights with B5 S4's?

Many, but not all. Easiest way to tell is the caliper bolt spacing. The HP2 caliper bolts are very far apart compared to the single piston caliper brackets. The A6 came with HP2 calipers, it's the same as the S4. The one small difference is the A6 that came with the 4.2L V8. Same uprights, but the wheel hubs are 5mm wider. Uses the same HP2 caliper, but a different rotor to accommodate the hub.

Not if you have a 2.8L. The wheel bearings are the same size as the S4 for all years.

[coolgraymemo]

Just buy my BBK.

but who would waste their money trying to get a 2.8 to stop faster

[Mad Cow]

You can also use any B6 upright (probably B7 too). The caveat is the hub sits 5mm higher which means the car sits 5mm lower, but worst case Ontario you get some rake so not a bad deal I guess.

[Davdraco1]

That might be interesting to see. All the control arms bolt right up with the b6 spindle? Anyone have pics of that set up?

[xdewaynex]

Do the 17z and 18z calipers have the same mounting points? Apikol brackets say 17z, but can you run 18z calipers on them as well?

[bhusted]

The mounting ears for the 17z and 18z are the same. The distance from the hub is different to accommodate the larger rotor on the 18z.

Edit: Also wanted to add that many of the reman 17z and 18z calipers sold by A1-Cardone and others do not include the cross-over pipes. So in addition to pads, lines, and rotors, you'll also need to buy the cross-over pipe for the caliper for ~$50 each.

[redline380]

I can confirm the a1 cardone's do not come with crossover pipes. They are $26/piece on ECS, but wont ship till June 11th. Porsche PN 95535196100 for 17z's.

I bought my a1 cardone 17z's from rockauto for $300 shipped.

[Davdraco1]

Can I make crossover pipes?

[redline380]

Can I make crossover pipes?

sure, but it aint worth it. It would take a while to get it right. and if keep in mind you would have parts cost, and probably tools if you don't have a flaring kit

[Seerlah]

Small lines are easy to kink with such a tight radius. Better to have a mechanical assembly line do it and save yourself the headache. Sure you can do it, but it wouldn't look half as pretty.

[Davdraco1]

52 bucks for two lines though? I redid some hard likes when I put my ss lines in and the parts are so cheap. I would still buy them pre made but it's honestly less then 15$ in parts for the two lines.

[Seerlah]

Source them on ebay. Ebay has everything. You just need to know how to search it.

[redline380]

Try to do it yourself. I'm willing to bet you'd easily have $50 and a few hours into making your own lines before you give up and just buy the pre-made ones

Thanks for posting this info, it will help a lot of people.

I redid every brake line front and back on a chevy pickup one time. Took a whole weekend but was actually pretty fun. Of course at my friends shop he had lengths and fittings and all the tools plus the lift. So I am kind of spoiled now wrenching on cars.
