Re-read what Marc just posted because he's right on. If this is your first DE, you won't be held back by the limitations of the car. Cross drilled rotors are an upgrade in almost every respect. They lower unsprung and rotational mass, and the holes actually dissipate heat faster because of the airflow and additional surface area of the metal (the heat does not have to travel as far to escape the rotor). The holes also allow the gases created by the friction and extreme heat between the pad and rotor to escape easier, making braking more effective. There is the risk of cracks developing between the holes, and they are generally more expensive to replace. It's a trade off, but for now, I would say that the stock brakes in good working order will be more than enough.
And, of course, everything I just said is always heavily debated, haha
