Which are better, or are they the same?

I know the GDs got upgraded to the Brembos, which is fade resistant and more stopping power, but I'm wondering did the USDM 06+ WRX inherited the same STI FHI 4/2s or are there improvements?

If it was a waste of Kaiba's time, he probably wouldn't have answered. There are a few threads with this information but you have to read through them because the information isn't all in one spot. It is nice every now and then to have someone actually answer instead of answering with an answer. :) Try that on nazicock and it will definately take less time to search. :lol:

Measurement and weight. The cylinder size on both jdm and 06-07 wrx are the same size.

Pre-ver.6 4pot 1.304mm



06-07 WRX 4pot 1.256



06-07 WRX 2pot and pre-ver.6 should be the 100% same beside the color.

And so they are direct bolt on with no modding to the brackets might I add. For those seeking alternative to JDM GC calipers, look no further! :lol: Good info!! Now this is very helpful lol Even though the facts were already proven somewhere already..
