Cross-drilled/slotted rotors question

I am interested in getting either some cross-drilled or slotted rotors but do they last long??

Would the brake pads wear out faster?? I would presume the slotted rotors would wear out the pads a lot quicker since there are grooves in the rotor.

Do they perform well??

TIA

For performance, slotted rotors work better and aren't as vulnerable to cracking like the cross-drilled rotors are. As far as pad wear, it depends on the number of slots/holes in the rotor; the more slots/holes, the faster the pad wear.

w/ slotted so it will not wear your pad out as fast.

do not go w/ cross drilled, if look is not important to you.

I recently installed the Bav Auto Ultimate Rotors, which combines slotted/cross-drilled patterns. So far, I can't really see any differences in performance, compared to the original OEM rotors.

Cross drilled and/or slotted rotors will NOT allow you to stop any quicker on the street. Why would anyone think they would?

Cross drilled for look, slotted for track. And slotted tend to last longer.
