I replied to a post with this question, but got no answers...

Is there a consensus on where to get replacement brake rotors (solid, no cross drill or slotting) for the least amount of money that will have at least equivalent performance to the stock rotors?

Mine are showing little surface cracks (non-structural) and they're blue in the outer half, where they get the hottest on the track. I figure I need a set of back-ups, if I don't just go ahead and swap them before this year's first event (Mid-Ohio Apr 8-9).

Thanks!
