Thanks for all these informations, I have 1 question about my STI, its year 2000 JDM V7 Wagon, the caliper is 4-pots at front, 2 pots at the back, subaru OEM ones. I really love the big gold brembo calipers, I was wonder if I can fit V7, V8 or V9 brembo calipers into my STI? As I've been told the front should be no problem, but not sure the rear. Do I need to change all those stuff u've mention in the thread for 2pot Brembo upgrade? Thanks alot.
