Ended up not doing it. Took the car back in right before the warranty expired and got the dealer to do rear rotors, pads, and sensors. Fronts are at 7mm, and I don't plan to track the car, so they'll last a while. Beyond that, working for Vivid Racing, I can get all parts at wholesale and have my shop guys do the install.
I did pick up the extended warranty though. Don't want to mess with rod bearing issues, or DCT replacement.
