I am looking at the JHM replacement discs using the OEM hats for my 07 RS4. Has anyone actually had experience with them?

I have them installed and no problems. I went with the larger 380mm. No regrets, had them on for about a year now.

Thanks! What kind of parts did you have to have to use the RS calipers or did you replace them as well?

And what pads did you use? I will be doing maybe 3-4 track days a year, so really need HP street pads, I think.

There have actually been reports of the JHM rotors warping. Especially with any kind of track use.

Were they the 365s or the BBK rotors?" I do 98% street with maybe 2-3 track days/year.

Yes - JHM have admitted a small number have had issues. Customer service on those issues have been lacking - for such a great company. Suggest one visit some of the other Audi forums out there for more inputs.

I ordered a set of the JHMs for my B7 RS4, but unbeknownst to me, my wife had also ordered a set for me as an anniversary gift. Mine bolted up with no problems and have given me ZERO grief since they were installed 6 months ago. I can't tell the difference between stock and JHM, though they claim that they cool more efficiently because of the slotting. They came with a pretty clear instruction sheet on how to properly seat the pads, and they claim that any issues with warping are due to improperly seated pads. I'm not trying to start a debate on whether this is true or not, simply letting you know what I was told. At any rate, I now have a spare pair of rotors (thanks to my wife) that I'm selling. They're new-in-box, never used, never installed. If you're interested, hit me up. I'm located in Seattle and local pickup is welcomed.

Steven, are they the 365's or the 380's? I am interested if still available.

Reggie, did you sell your Ibis RS4 privately or trade it on your RS5?
I have a friend looking for one and if it is at a dealer, I would go look at it for him.
