I got my "big brakes" yesterday from a junk yard. The rotors have about a .4mm lip on the back side only (weird?). I can turn them, but they will just barely be within the minimum thickness cast into the rotor (22.4mm - they are at about 23.4mm right now). Autozone (or was it Advance?) has replacement rotors for like $30 each. I can return the jyard ones I have, so which way should I go? Is there really even a need to turn the stock ones? I plan to use the pads that are in the calipers I got for now (they look fairly new), as I am short on funds, but not sure if I can do that if I go with new rotors.
Also - I noticed two "W" shaped wires pressed into the vents in one of the rotors. I removed one of them to look at it, and it looks as if it was designed to fit in there. What is that? Should I leave them if I use these rotors, or toss 'em?
Thanks.
