I purchased all 4 lightweight ones for my allroad project which has all 4 new RS6 calipers, hubs, bearings, uprights, etc. etc. Bed-in procedure was done properly following the recommended famous Stasis article referred to many times (even by JHM themselves).
Within about 15 miles after bed-in, I noticed I've got major pulsation with awesome wobbly steering wheel. They are warped. I've tested the rears only use p-brake and they are also warped but only slightly. I've been in touch with JHM and it's not going well. I've done many brake jobs prior and never experienced anything like this. JHM is saying the bed-in procedure was done wrong and I have pad deposits on the rotors causing the pulsation. I have several emails from JHM dealing with this but quote is my favorite: "There are no such thing as “warped rotors” it is just a misconception."
Before I blast JHM publicly for not standing behind their product and at least trying to work with me (they are denying anything is wrong with their product), is anyone running these and what has your experience been? I know there have been reports of these rotors getting warped after track use or beating on them with daily driving.
To prove a point, I have installed full set of OEM RS6 rotors, followed the bed-in procedure exactly as I did before... no issues at all on the OEM set. I was hoping to put the OEM set on my RS6 and leave the JHM ones on the allroad. argh!
Input from the brain trust appreciated.
