It make any sense to just upgrade rotors?

Im a noob as well but arent the slotted/drilled rotors for cooling the brakes? it increases the heat release on the brakes.

rotors with slotted/drilled while braking at high speeds imagine this on a regular stock rotor that dose not release heat that equals

Slotted provides no extra cooling, while drilled only provides a little bit of extra cooling. The picture above shows glowing carbon/carbon brakes -- which are totally different to cast iron.

The benefits to cross-drilling and/or slotting are related to initial 'pad bite' at higher speeds. If staying with the OE calipers, the best solution for better bite today is the J-Hook face pattern. These provide the bite of cross-drilling without the concern of premature cracking if used on the track.

The other things to do at the same time are better pads, stainless steel brake lines and fluid.
