i've never actually bought and installed brake rotors before. even before my hypermiling days, i've never been hard on brakes. i've got some fantastic pads picked out(NAPA Adaptive One), but i'm uncertain about which rotors to buy...
napa has a "premium" rotors for $15.99usd each and "ultra premium" for $32.99 each. not being hard on brakes like most of us are, are the reg premiums acceptable? for half the price, life of rotor makes no diff. warranty is the same, with the major diff being a "no turn" guarantee and "quiet" tech.
edit: i'm assuming paying $15.99 is better than paying to have the old ones turned(if possible--pretty well worn)
I never turn rotors or drums. If you keep everything in good working order they don't get scored, and there's no problems. Also, at $15.99 for new, why bother paying (and waiting) to turn the old ones? I'd buy the $15.99 ones and not worry.
I vote for the cheap ones too. I've almost always done well with cheap rotors.
Does the "no turn guarantee" mean that you'll never need to get them turned, or that you won't need to get them turned before the first time you install them? Sounds silly but once I bought cheap rotors like that and found out I had to get them turned before installing...
I'd imagine the 'best' may say 'no turn guarantee' sounds like they are guaranteeing you no need of turning the rotors, as it's hard for me to imagine Napa brand rotors asking to be turned after you buy them...but HC's experience leaves the door wide open.
You would think, though, that the no-turn deal if in the positive, would be in regards to the more expensive part.
I bought some cheepies (around $17 each) from a local chain auto store. The first set had one that was so bad I drove the car around the block and drove back to the auto store. They put it on a lathe and said, oh, these are awful! I made them put two more sets on the lathe before I would buy them. (finally found a set that were okay)
If you can get them to show you on a lathe that they are fine, buy em'.
