Um...Yeah, that EBR rotor is $400 from AF1 Racing. The EBC rotor is less than half that and EBC is still a good manufacturer. At least, I've heard good things about them. The EBR mounting hardware is something I'll certainly consider. But the rotor is definitely warped. I can feel it in the lever at slow speeds kicking back a little bit. At least, I'm really hoping it's just a warped rotor and not a bent wheel. Or is that an irrational fear?
