After a couple days of searching im going with Stoptech replacement rotors. I had there stage 2 slotted kit on my IS300 worked great for my driving style somewhat aggressive or highly spirited they seem to be the only ones with a front and rear drilled package. that is an oem replacement and not a big brake kit.Raybestos has just fronts. If someone can get it approved I can post who has them in stock for a great price but i dont want to violate any posting issues here as I am not a vendor. Or i guess PM me if thats allowed.
