I have a few a questions regarding BBK's. For the people just casually viewing the thread, a BBK is a big brake kit. Now before I get flamed by some of the community, I know mostly all there is to know and understand about the difference between BBKs and just upgrading the stock braking system. I understand that i MAY not improve my braking distances if done improperly or incorrectly. I currently use goodridge lines, ebc greenstuff pads, and ebc dimpled and slotted rotors. I love this setup but in all honesty I just want to set my car apart from the rest. Now i realize in stating that, i leave myself open to bunch flaming but its completely true. I realize that the setup i currently have is ideal for street use and the occasional track use (purely in the spring/summer) I see. But can anyone deny how perfect a BBK accents the wheels and the overall appearance?! Now my question to you guys are, for the people that own BBKs what is an ideal rotor size that wont affect my brake biasing and will give me as close if not better than my current setup?
