brake rotors

[autojoe]

I bought this trailblazer in 2012 feb....installed autozone brake rotors front june 2012.I do not know if they were the originals.2 years 2 months later rotors rusted out.my question is local dealer dont have the rotors that came with my truck originally they have advantage plus or something like that lesser quality rotors but online I found the oe ones that came with my truck and I can get them for 25 dollars more for each one for a total of 50 dollars more than az rotors with 2 year warranty.I think the oe ones have a 1 year warranty......does anyone know if the oe ones online will last longer than 2 years?I live in Pennsylvania the rust belt.I do not want to pay 50 dollars more for 2 rotors and still have to replace them every couple years.I do not mind paying more and replace less.Any input would be appreciated.

You can pick up an OE set here for about the same price, and for $8 you get a 3 year warranty on them. IMHO, that's worth it.

That is 61.00 plus shipping.I bought autozone duralast gold rotors with 3 year warranty that includes rust which most warranties dont warranty rust.....they are made with high carbon steel and have a zinc coating on non friction areas and on edges for 61.23 each.I am going to see how long they last.the oe ones that came with tb lasted 4 years.....local dealer dont have they have a cheaper version of ac delco rotors that came with my truck called advantage.gm parts direct have the exact oe rotors that came with my tb for 150.00 for 2 that includes shipping.if these dont last 4 years that will be my next option.thanks for reply.I also got free shipping and 20% off on autozone website and with tax paid 105 dollars for 2 rotors duralast gold with 3 year warranty includes warranty on rust.
