TCE and Baer make big brake kits. If your looking for just slotted or drilled OEM size rotors, I'm not familiar with anyone, but I think I remember reading that they do exist somewhere.
The Steeda catalog says they have slotted and "dimpled" rotors... Don't know what the prices are though (said to call). Baer has a 13" kit $799-$899 w/ slotted, crossdrilled zinc washed.
If you are going to buy brake upgrades do not buy drilled rotors because they will crack. Sloted rotors or keep the stock rotors plus high performance pads are the way to go. Also buy stainless steel brake lines. This will give you a great brake system.
