I am planning to purchase J-Power brake rotors and was wondering how in the world I can upgrade my calipers. Would J-Power Rotors be compatible with a Caliper from another company i.e. StopTech, FastBrakes, Endless, Brembo, Baer, or would I be stuck with just using the stock calipers? Is there a caliper upgrade for the EG Civic Si? ---edit--- I used the search button and found that Brembo Blanks work ok too. I'm planning for street/auto-X on weekends. Which would you think would be my best bet? J-Power or Brembo Blanks?
