So for the BBK upgrade, it would be wise to buy a set of 2008 STI calipers and just get 2004 front rotors and dual drilled 2008 rear rotors from KNS?
Check with KNS brakes. And, from the original thread, my understanding is that the STI Brakes are a direct fit for the front...rotors included.
You need a kit to make the rears fit.
However, you can go the 2008+ WRX route and they will all fit (replacement/upgrade parts for worn out parts)
Going the TI/Brembo route would cost me around $2000 in parts alone. Before I do that, when I'm getting replacement parts, I will get steel braided lines, slotted rotors, and better pads. (I know the slotted rotors will make the pads wear faster...I just want the "bite")
