Quick question. I have an '00 RSTI. I just got a set of '04 STI Brembos along w/slotted '06 WRX rotors. I know the fronts will fit, w/no issues. But as far as the rear, will I only need the adapter brake shoes & rear conversion brackets? If so, will I also need rear '04 STI rotors or will my '06 WRX rotors be fine? Thanks!
