how much was the entire brake setup? is it worth it?

It was about $2300 installed. Note, though, that a large portion of that cost was changing the calipers, which was a purely cosmetic change. I haven't been to the track yet, but I have been very happy with the performance while canyon carving. When I bedded them in I really got on it hard and they held up well. I think it was worth it for sure.
