Ok... I'm "new" here but come from aerospace manufacturing and had my own rally car business for quite some time, raced a bit in SCCA tarmac and a little dirt, bla, bla, bla.
Cliff notes:
Turning rotors is usually bad/unnecessary regardless of shade tree myth and brake shops wanting your money.
Scuffing old pad material off and just replacing pads saves money/less WASTE!
Cmyrunner, in layman's terms, when you get your new rotors/pads don't let some jack ass in the future lie to you (or misinform you) that your rotors need to be "turned". In MOST cases all you are doing is removing the precious mass that the system uses to transfer/dissipate heat. People will tell you, and old shade tree myths you grew up with will support that they are "warped" because you can feel the pulsation of the pedal and the "grab/release" of the pads as you come to a stop. What it really is IN MOST CASES is uneven pad transfer. When you properly bed your brakes a thin layer of pad material is evenly transferred to the rotor. With crap pad material or pushing even good material passed it's thermal capabilities the transfer becomes uneven causing these high spots in the surface. Hence the "feel" you get.
For almost two decades now I've never allowed my rotors to be "turned" on both vehicles for business and personal. All that is required (if you do your own work) is genitally taking a wire wheel to knock the old compound off the rotors surfaces. Don't cut into the surface, but more so a light scuffing. I had a little terror of a rally car that went though countless sets of Ferodo DS2500/3000s (about $250 a front set) and Brembo pads on a single set of rotors. I always "scuffed" and mic'd (measured) them to knock the old compound off and make sure they didn't wear too thin to be safe. I've done the same on both my 07 FJ Cruisers one of which was traded for the Wife's new 2014 TE Premium. That vehicle will get the same service. OE or equivalent pads and a good scuffing for new pads IF I change compound or feel anything in the pedal.
Last, a good non OEM rotor is Centric Premium. Has to be their Premium line though as they caved on the eco series. I'll be happy to provide anyone who wants a contact someone who might give you a price break for dropping my name but don't want to break any rules. When the business went away I lost contact with him but still have his info.
...and I've given up on any forum discussing the folly of cross drilled or slotted rotors on less than a high end street/race car.
