You could consider an RB rotor kit upgrade (semi-BBK). As well as StopTech, other expensive BBK alternatives are Alcon and AP Racing.

Also, talk to Pete@Advan about the Nashin BBK that Advan sells. Some more discussion here.

Don't forget to upgrade to stainless steel brake lines and perform a fluid flush (full bleed) using brake fluid with a high boiling point, e.g. Motul RBF600/660 or Castrol SRF.
I've heard that the RB quality is questionable and that there are some issues with their product. I'm not sure if they've addressed these issues yet but I wouldn't recommend it.

I went with Stoptech BBK and couldn't be more happy. They get a lot of attention too.

OE is probably the best option and you almost always get what you pay for. ECS look quite good but if you track your car hard I wouldn't recommend them, or any cross-drilled rotor for that matter. I've had some hairline cracks in my first set of Performance rotors from track abuse.
