JonB will likely be available tomorrow, they were supposed to be back this afternoon taking care of emergency orders 1st. I'm weighing which rotors to buy to for my '02 ACR, JonB has slotted with dimples for $639 for the set and $499 for curved vane slotted rotors (set).
If the dimpled ones have curved vanes, I'll buy them, but if they are just dimpled and not the curved vanes (for better airflow) I'll opt for the cheaper set.
As mentioned by Ken, Roe has some nice options...you can search for the Tom's 40mm brake option as well and there's also Zeckhausen Racing as well.
Those are the options I've been checking out, brake pads were a lot tougher for me to choose than rotors, but I wish you all the best in your search!
