pad material is a great study an makes major improvements in certain conditions.. period.. it does.. and fluids boil so better cool it an run what works more then any thing
read stuff off the search about pads an you'll see studies..
cooling kit might be the single best improvment to that system.. it just friggin works..

I don't like drilled or slotted rotors, more surface area= better braking. Want cooler brakes? Vent 'em.
Hawk HPS pads, motul and stainless lines. Blues or better for track days.

The purpose of slotting and drilling is to vent the gasses that form at the pad rotor interface during heavy braking. Flat pads on a flat rotor surface is essentialy like an air hockey puck.....vent that gas and the brakes will bite more. Cooling is a whole other animal.

gotta like that... so, it doesn't eat more pad material.. or it does and it releases the trapped gas...

It's an ongoing debate about drilled or slotted rotors, most race guys don't like 'em. They consider the rotors a wear item that needs replacement fairly regularly, and cutting or drilling the rotor weakens it and costs extra money and time. Generally not considered worth the effort on our cars.
But there is a strong case for the trapped gases argument. But I believe you will see a more dramatic improvement with a simple pad replacement. If your brakes ever fade, make sure to replace the fluid. Use Motul if you depend on your brakes in spirited or track driving.

Trapped gases aren't as much of a problem anymore but the slotting does keep the pads cleaner allowing dust to escape.
Drilled will eventually start to pressure crack around the holes, even cryo-treated, just takes 200-300% longer.

From what you said STock pads and rotors are puuurfect. If the rotors have enough meat left then turn them.
I don't track my car but I like to beat her up once in a while
OEM pads
Gruppe-S ss/braided teflon coated lines
SP-slotted rotors
ATE brake fluid
and its feels great!

I just install a complete set of DBA4000 rotors , stock pads and stainless lines that has made a world of difference. The DBA rotors are slotted allowing cooler operation so not to over heat the stock pad as easy. You can't beat the pedal feel with stock pads.
