Default Anyone here use the Phaeton two piece rotors?

I have been researching this on rs6.com and on here, found part numbers, but no luck locating them...

Anyone have a source for these? Part number is 3D0 615 301 N.

***(after doing some calling oempl.us has them for $400.00 each)**

Looks very promising, as they should reduce the unprung weight by ~5lbs a corner.

Thoughts on this setup?

Part is shown halfway down page.<ul><li><a href="http://www.rs6.com/forum/showthread.php?t=16747&amp;highlight=phaeton">http ://www.rs6.com/forum/showthread.php?t=16747&amp;highlight=phaeton</a</li></ul>

Don't think they will be lighter as our is really two piece just not a replaceable ring.

Default Ours are all steel, and not a tru floating design, you think 5lbs is unreasonable?

Most after market 2 piece setups save ~10lbs per corner.

RS6 disc hubs are aluminum not steel.

Default They are also an excellent full floating design

This is the same design BMW uses for its factory floating rotors (radial pins). The only shortcoming is the pin type of floating disk causes an obstruction of cooling flow to disk vanes.

To this day, however, I cannot get over how much those things weigh! BTW, 5 lbs is very significant.

Yes, the hubs are aluminum and definitely a floating design.

Do you happen to know the weight then? I'll see if I can get the phaeton rotor weight.

Default I have some new fronts at home, I'll get the weight tonight. I think there was a RS6.com....

thread a while back about the Phaeton rotors, they were a little heavier but quite a bit cheaper.

If the Phaeton rotors are heavier then I lost all interest in this, I thought they would weigh less
