New brakes - Silver Zinc Plated Cross-Drilled And Slotted Rotors w/Z16 Ceramic Scorch
now at 90,000 miles, I am needing new brakes and came across these at Rockauto. anybody have any inputs on these?

For rotors: Go with OEM which actually offers one of the best braking performance. If you want more initial bite, go with slotted rotors. Drilled ones are prone to crack, even high end ISF OEM drilled rotor crack in just 1 track session. Drilled rotors are just for show, no more no less.
For pads, go with OEM or Hawk performance.

If you aren't tracking your car you will have no issues with drilled rotors other than a decrease in pad life. If you plan on tracking your car then for sure stay away from drilled rotors. Like everyone else here has stated a good set of blanks (OEM or Centric Premium) can't be beat. If you want the sporty look and don't mind changing your pads out about 30% faster go with drilled or slotted but they will not improved your braking performance on the street.

I agree with these guys. Blanks for performance, drilled if you like the looks. I recently got an M3 for track duty, and it came with cross drilled rotors. The rears are fine, but the fronts are cracking on almost all the holes. Fine for a little street, but they need to be replaced before it sees the track.

Yes.
Drilled and/or Slotted Rotors are great for track use but for daily driving, what I am assuming most of your driving will be, they can wear pads faster and require more maintenance. It's not that they are "not as safe," they just require a little more maintenance. Most use them for show only. If you want to increase your stopping power, the best you can do is purchase high quality tyres.

To confirm, you cannot resurface Drilled and Slotted Rotors.

Drilled and slotted rotors are good for dissipating heat as it prolongs brake fade or the reduction of stopping power (http://ebcbrakes.com/articles/what-is-brake-fade/) during hard and or sustained braking, which rotors can experience during tracking. That's why they are good for the track but yet are more prone to cracking (due to adding stress concentrations by drilling holes or milling slots into the rotors with repeated heating and cooling of the rotors). Selecting drilled/slotted rotors is more of a compromise for mitigating the chance of brake fade during tracking over a stronger rotor which can be more susceptible to brake fade during tracking. This is of course dependent on how one drives when they track.

There is a big difference between drilled and slotted rotors. Drilled is more prone to cracking but slotted is NOT. Also, stopping distance is not reduced regardless what is being used. Slotted rotors offer more initial bite than blank which might make some feel the stopping distance is shorter but it is not. Even big brake kit is not going to help you reduce that stopping distance much. The main benefit is avoid brake fade during hard and sustained braking on track.
Also, one thing i want to add is that the noise level associated with both drilled and slotted rotors are loud on some car!

Way back when (decades ago) the materials used in brake pads produced gas when they got really hot, in some cases cars on a track would lose brake power because the pads produced enough gas at a high enough pressure that they would prevent the pads from touching the disk. The solution (again, decades ago) was to drill holes in the rotors to give the gas someplace to escape. This came at the cost of reducing the life of the rotors because they would crack. Not a problem in the racing world, especially since it kept the brakes working. Decades later most people still think drilled rotors means "racing" brakes. The next step in this evolution was slotted rotors, they gave the gas a place to escape and they weren't near as prone to cracking as drilled rotors. It has been a long time since brake pad manufacturers fixed the off-gassing problem. There is no performance benefit to drilled rotors, other than the looks. If anyone likes the looks of drilled rotors, look for dimpled rotors. Same look, much less prone to cracks.
