phaeton disks

[Gavinda]

Have read about the phaeton disks being a cheaper option for the rs6. ive seen the rears for £42 a pair compared to 400 for the rs6 ones with drill holes,
are these a direct fit?
also quite like the floating front disks .

[Gavinda]

Seems there is a few millimetres difference between phaeton and Rs6 disk offset . Caliper needs spacing out
Is this the only issue?

Pretty sure there's no practical way to get Phaeton front disks to fit, but I'm willing to be proven wrong if you can post some dimensions.

Dunno about the rears. At that price you can get a pair and offer them up. I am pretty sure that they won't fit either though.

Don't the Phaeton discs have a steel centre instead of alumnium? The proper ones are too heavy as it is IMO, but that's quite a price saving if they do fit.

I think the Phaeton disks are like the B7 disks, ie on a removable bell. The RS6 ones are all steel.

Ah ok, although you might wanna have a closer look at the RS6 discs. I'm holding a genuine rear disc and it's non magnetic and unlikely to be stainless

Sorry, I'm talking about the fronts. Haven't seen the rear disks for a long time, although they are crying out for attention on my car. I knew I forgot to do something last week.

Slightly off topic, what are the brakes on your M3 like? I've always thought they look a bit small, but I guess the car is quite light?

[Shoppinit]

From what I read online, I thought they were going to be sh!t. So much so that I almost ordered a big brake kit even before getting the car. But I thought I'd try them out standard first.

I have now done a number of track days with standard set-up and DS2500 pads and I can tell you that they stand up to some serious abuse. In all honesty I don't think they could have taken more of a bashing and they weren't phased at all. My tyres turn to goo before the brakes work up a sweat.

Last track day was a couple of weeks ago and it was the same story. We also had a E92 M3 with the standard single pot (ghey!) calipers and DS3000 pads and it was the same story although he's not so heavy on the brakes. Not heavy enough 'cos the DS3000 are pigs when they're not being worked very hard indeed.

Just goes to show, don't believe everything you read online until you've tried it for yourself.

Impressive! I guess with decent pads and fluid the temp of the disc is slightly less critical. Actually following on from that, the hotter it gets the faster it can dissipate heat. The M-sport boffins have obviously got it right!

Just goes to show, don't believe everything you read online until you've tried it for yourself.

That's a good point

[Shoppinit]

I still think a single pot caliper on a sports car is embarrassing though.

Also, I wonder if I would find the limits of the brakes more easily with track orientated tyres rather than road tyres.

I'm sure I've read elsewhere the phaeton disks fit the rear, the calliper just needs a washer to pad it out?

Offset is identical (x-axis), but it is impossible to bring the caliper out 2-3mm along the y-axis without drilling something..

The rs6 discs aren't 1 piece, they're floating on an aluminium hat.

This is what I read on bere

Hi all,

Just a quick knowledge share on how to avoid the Audi main dealer prices for replacement RS6 rear discs.

My rear brakes badly needed replacing as my pad had corroded and left metal on metal under braking, so I started to investigate what my options were.
Having driven BMW's in the past, I was quite shocked to see how little alternatives there were to RS6 brake parts. My Z3M Coupe's parts were nearly all from the E46 BMW M3 and surprisingly reasonable on the wallet.

As the rear brakes were the first work I had to carry out on the car, I was shocked to see that discs were starting at £300 each from main dealer. Maybe this was less elsewhere from garages that I didn't manage to find, however I was sure there must be alternatives.

I saw on this forum and others that people had managed to fit the Volkswagen Phaeton 6.0 W12 rear discs onto their RS6 and I was intrigued to see if I could do the same and save many £££'s.

So I went out and bought the following,

VW Phaeton 6.0 W12 Rear Discs
EBC Standard Brake Disc
Vented - 5 Bolt Hole - Diameter 335mm - Height 42mm - Thickness 22mm
Model No - D1418

RS6 Yellowstuff Rear Pads
Model No - DP41470R

I saw on a forum that someone mentioned that I need to put washers on to make the disc fit, but for the life of me could not work out where.

So the disc went on and immediately I noticed that there was a problem.
The drum on the disc is shallower than the Audi part and therefore does not sit so deep into the car. I then worked out this is where my washer comes into play.
I took the caliper carrier bolts out with an allen key and put 2x spring washers (2mmx15mm) on the inside of the car and then put the bolt back in. This sufficiently brought the caliper out away from the car to center around the disc again.
My only worry after this was whether the caliper would now touch the wheel, however upon fitment this was not a problem as there lots of clearance.

And that was that. What went from being an £800 job turned into a sub £200 cost.
The cars bite feels strong and true under breaking and for everyday driving they seem very satisfactory. Most happy!

I have linked some pictures below for reference. Please excuse the oily mess, a leaky DRC is being replaced next week. I have the PSS9's in my hand. Oh they are beautiful and I'm itching to fit them.
