wats better suited for street use? i heard many different things from many people but no clear answer.

 

Anything is acceptable for street use. A lamborghini will take you to the grocery store on the street just as easily as a geo metro. Unless you are going to use the rotors for their full potential, it doesn't matter.

 

For street, just stick with blanks, or at MOST slotted.

Cross drilled is mostly just for looks, you'll almost never get your brakes hot enough to make them effective unless you are running LeMans or something. Cross drilled rotors weaken the rotor and are more prone to cracking, they also take away a lot of surface area. The less surface area you have, the longer it takes you to stop. So if you have a 13" rotor with a bunch of holes in it, you might as well use a 10" blank rotor.

The purpose for both is to keep the brakes cool, and also to expell hot gases that are cause from the friction between the brake pad and the rotor. These hot gases form between the pad and rotor, thus reducing your stopping power, or giving you "brake fade." These gases can come as soon as 1 quick stop. If you slam on the brakes really hard, just once, it can get hot enough to cause this. However a slotted rotor loses very little surface area, does not weaken the rotor, and will give you enough to expell these gases quickly. However slotted rotors will eat at your pads a little faster.

So with all that said, blanks are probably all you really need. But if you really feel the need to put something diffrent, then get slotted only.
