I already had the dealer replace the front rotors when the car was under the original factory warranty, now they are starting to shimmy again at 57,000. What options are there for rotors that won't warp as easily? (I am trying to hold down my costs) Thanks in advance, Drew

Sometimes pad deposits make the car shudder as well. Check that first by doing a series of 60-10 MPH runs, then drive around a while to cool the rotors down before you park the car.

If that does nto work, try irotors.com or ecstuning.com for Zimmerman or Brembo rotors. larger venting area than OEM rotors, so less likely to warp.

Pad deposition can accumulate erradically and cause the "shudder" you are talking about. Braking at high speed effectively scrapes off the uneven layer while creating a new one.

FAQ #3: What do you mean I â€oeun-beddedâ€� the brakes?

If any brake pad is used below its adherent operating temperature, it will create friction through primarily abrasive mechanisms, slowly but surely removing the transfer layer on the rotor. For this reason, most street/performance pads like to be driven just a little bit aggressively every now and again to maintain a proper transfer layer of pad material on the rotor face.

If the brakes are used passively for an extended period of time, the transfer layer can be completely removed, effectively un-bedding the brakes. The brake system will still perform well under normal driving conditions, but before heading to the autocross or your favorite canyon back road you will want to perform a bed-in procedure. Failing to do so will only increase the risk of TV generation.<ul><li><a href="http://www.stoptech.com/whitepapers/warped_rotors_myth.htm">http://www.stoptech.com/whitepapers/warped_rotors_myth.htm</a></li></ul>

There are aftermarket rotors that are reasonably priced and seem to hold up better than the Audi rotors. The DBA rotors from AWE worked for me.

Thank you!

80 - 100 may not be necessary. StopTech recommends 8x 50 to 10mph
