Title pretty much says it, I'm wondering if I need to buy new rotors for my new Porterfield RS4 race pads. I'm coming from a set of Hawk HP+ pads that I went through pretty quickly, so the rotors still look very good. They have no visible cracks, grooves, or surface imperfections. I checked out the rears first, and though ok, I'll just get the front rotors, but then looking at them, even they done look worn. The pads are actually still at about 50% towards the inside of the rotors, they're just almost to the backing plate on the outside.

So, opinions? Cheapest I can find is $70 total plus whatever shipping is from the site linked in M-tune's big brake kit thread. That's $70's I'd love to not have to spend right now, but if it compromises my $190 pads in terms of longevity or effectiveness, I'll go ahead and and purchase them.

if they look good then just shave them

mic them for thickness, then run em again. The pads probably won't last much longer with big brake kits, but they will run much cooler.

If they mic OK take a sander to them to give you a new surface, for the new pads to break in on, or take them somewhere to get turned. I've toasted mine a couple times on track days (the surface looks friggin melted) and have had them resurfaced each time. I'm on my 2nd resurface and I'm still well within spec.

I got my rotors for $45 for all four. Got them from R1 Concepts, they get their rotors from Centric.
