I know the factory rotors are garbage, but other than that I don't know much. Would just about any slotted and/or drilled rotor be better than factory or do I need to get expensive ones? Any help would be appreciated.

 

the slotted/drilled rottors help with heat disribution. also zinc plated looks nice too.
search ebay you can get all 4 rotors+rads for under $200

 

Is it worth upgrading the back brakes?

 

Also consider replacing your rubber brake hoses with stainless steel braided for improved performance, you will notice the improvement.

 

If you go to http://brakeperformance.com and you can get dimpled and slotted rotors, they are lifetime guaranteed against warping and they are less likely to crack, they are zinc also so they wont rust.you also get a free set of performance pads if you buy front and back rotors.
