Cheap discs?
 

I am planning on getting Wearever YH145657 for the front discs and Wearever YH248479 for the rear from Advance Auto. It's all about $118 shipped. I've read mostly positive comments, and they're cheap as dirt. Any thoughts for or against? I'll be using them with PFC 08 pads.

Are your stock rotors broken? Are you getting these because they are bigger?

I want an extra set for the track in case I warp them or ruin them somehow. Stock rotors are fine, at least for now. I also don't know how quickly they'll wear with race pads.

Are these really much bigger? They're listed as the replacement on the BRZ.

Stock rotors are fine. Just put on the proper pads and flush in the proper fluids. Warping is pretty rare, but obviously you can warp anything if you don't put any sort of consideration for how you warm up and cool down the brakes.

Centric rotors are also good and cheap alternative.
