Looking good. I'd say go with red calipers. I did my bbk and sort of regret doing black, mainly because red bbks look awesome when the car is moving.
I am assuming those are the 18z 350mm calipers? If so I would highly recommend the EBC Red Stuff brake pads, ceramic, perfect for street and light tracking. No noise if bedded in proper, and super clean, I mean almost zero brake dust clean.
