So, first thing, your selection of rotors (crossed drilled and slotted) is not the best for the driving condition you type of. The crossed drilled holes will crack due to the extreme heat/braking cycle. I dont recomment them for normal street use for the same reason, they are pretty much only good for show and paperweight. However, if you have the $10k set designed for super sports cars as that is the only exception. Get yourself some heavy duty rotors desiged for excessive heat handling capabilities with matching pads and you should be good to go.
Second. Flush your brake lines of that crappy factory fluid and replace with castrol racing brake fluid. This will prevent boiling and loss of pedal.
Third.. replace your brake lines with braided stainless. Do this prior to adding the castrol racing brake fluid.
Finally, the factory two piston front calipers are sufficient in heat transfer and stopping power. The right brake pad with right brake fluid will make a huge differance alone.
Side note, you may want to replace your brake proportioning vavle with something more adjustable so that maybe your rear brakes are engaging quicker or 50/50 front/rear to keep the brake temps down.
