I am going to replace the rear rotors in my 07 expy. Autozone and advance sell them for about 70 bucks a piece. Rockauto.com has some for about 30 bucks. Have any of you guys used them? They are pronto brand if that helps any

 

I just put a set of Centric Power Slots on my Naviigator p/n 126.65120SL and 126.65120SR for the rears. I have used power slot rotors for years on different vehicles and had good luck with them, they Make a good quality rotor.

 

I used Autozone gold last year
no complaints.
They are about $100 each, and coated with a black coating to prevent corrosion. You do not clean it off before using. The pads will clean the wear surface only.
They always have deals, I was able to order two fronts, and get the 25% off and a $10 gift card. Then did the same on two rears.

 

I used Raybestos professional grade. Work great.

 

I've warped them all, but had the longest lasting and best results with Raybestos. Currently using the Advanced Technology series.
