OK.. i plan to upgrade my brakes soon. and was going to get slotted rotors... (not xdrilled, b/c they crack)

how deep is the slot. and is it possible to have them surfaced after a while?

 

i dont think they can resurface slotted rotors my buddy got ones on his z28 and tryed to do so and they told him no.

 

so it is hard to resurface slotted and drilled rotos? i have slotted and drilled rotors on my max and im going to get the front pads changed, they are pretty worn. the rotors have like circles around it with small grooves, i hope they can resurface it or im putting the pads on as it is till i can get new rotors.
