I'm looking to keep the brembo calipers and just upgrade the rotors. How big can I go? Will I need to purchase brackets for the stock Brembo calipers to fit. If so where can I buy them? Looking for some cross drilled slotted rotors...Which ones do you guys recommend I look into? Thanx for the help.

 

DBA makes a good replacement rotor for front and back.
Check out 350EVO, they sell them.
