Brakes

Okay guys so have a question dealer says I need new front brakes and rotors... Just hit 30000 miles I find it hard to believe the rotors need replaced but the brakes I can see.. They quoted me 3000 just to do the front. Which is outrageous. I was thinking of doing my self and going with powerstop z23 warriors. Any experience with those? Also the sales representative told me that kit only lasts about 6-8 months which I find crazy as well???.. I'm going to get a second opinion or look myself to see where it stands if I even need them. So any information on the kit I'm looking into or any suggestions on different brands would be appreciated.
I have a 2016 dodge challenger srt hellcat.
