If you are going to upgrade then don't spend any kind of money replacing stuff. Just get some new pads. You can probably get by without getting a new rotor. If it ends up you need to replace the rotor and pads then email me... I have some stock rotors and pads with lots of material left on them that I will sell you for cheap.

Oh and I have heard the AEM upgrades are nice, they had some problems with the rotors cracking but I haven't heard anything about that in quite a while.
