A big brake is overkill for a non tracked car. The big benifit is being able to soak up more heat to avoid fade. Not something you have to worry about too much on the street. It won't reduce your stopping distance as your stock brakes can likely overpower the traction your tires can provide. If you were running aggressive rubber, then it may help to go to a brake with a larger friction surface. A big brake kit would also add to unsprung mass, and mess around with your brake bias.

Also no point in cross drilled rotors. They can be more prone to cracking.

Good pads, quality oem spec rotors, good fluid and enjoy.
