Obviously an old post, but did you end up getting the rotors and pads? im thinking of doingthe same
I ended up going on ebay, found a full set of used painted calipers, slotted/cross drilled rotors, and pads, all for $300. They were off a VF SS so the rotors are about an inch bigger than my old v6 ones (just gotta make sure you get the bigger caliper brackets to fit over bigger rotors). Brakes are heaps better now! Way better bite and a lot more consistent when braking for longer than usual (for eg: riding brakes down a big hill or something).
If you can find something similar I'd 100% recommend. Half the price of brand new rotors and a way better upgrade.
