LS1 brake conv....New Rotors??

I'm doing the brake conversion and eventhough the rotors aren't bad on the set i have, I was wondering if I should purchase some powerslot rotors or something along those lines. Do you think it would help much or would it not be worth the money? Any suggestions are helpful so thanks.

Personally, I'd buy new rotors and pads. You can try reusing the rotors, but you definitely need to check the thickness and runout before doing so.
