I have a 99 328i (Dinan 3) and I want to upgrade the front brakes on my car. My dilema is slotted vs cross drilled. I have heard that slotted rotors are noisy and difficult to cut. I really don't plan on racing the car but I would like the added braking power. Any thoughts on this would be greatly appreciated

Niether will benefit brake torque. Both slotted and x-drilled are difficult to resurface (cut).

Slotting helps in fade and does give a bit better initial feel.

Cross-drilling is basically for looks.

If your not tracking the car then I would suggest upgrading the pads, the fluid and if you want the hoses.

My recommendations:

Pad - Axxis Ultimates
Fluid- Ate Super Blue

and you can add stainless steel braided brake lines. Though these only help feel and only under high pressure.

You can click the link in my sig and read the sections on Brake Performance to see what increases brake torque.

Neither slotted or cross-drilled will increase your "braking power". Save your money unless you just want to spend it to look cool.
