This will allow it to absorb less heat. So, you will not see any miracles from a set of cross drilled/slotted rotors. Catchy names, shiny parts, great marketing, but they are still "just rotors". Pads...the pads will make a difference (and for much less money). Rotors are still a wear item, and for the money they are asking, I'd hate to run aggressive pads that chew up rotors on slotted, drilled or Eradispeed rotors. However, those same upgraded pads will stop your car and very well. So, I'd buy $60 rotors and $100 pads, instead of $20 pads and $800 rotors. You'll be happier with the result.
Be safe!
