I have had the same brakes and rotors since 2010 and I have 54,000 miles on my car now. I bought my car back in October of 2010
Brakes are doing great. I have a manual tranny so I downshift a lot instead of trying to slam on the brakes. My tranny is also doing great.
The brakes don't need to be upgraded unless you are doing auto-x type of competition.
If you did anything you could do a swap to GT rotors/brakes in the Front that wouldn't be too bad of an upgrade. I believe that's what some people are doing.
