I have a 95 Civic EJ1 coupe with a DC2 Type R 5 lug with Spoon calipers up front and ITR OEM rear calipers. My rotors are Powerslots front and rear. My pads are Hawk HPS front and rear.

My brake booster and master cylinder is from a 2000-2001 GSR.

Is there any difference in function and feel between what I have and an ITR booster/master cylinder?

 

try it and let us know

 

If i recall, the only real difference is that a JDM ITR MC will actually allow your hard lines to bolt up directly to the MC whereas your GSR one probably needed the line closest to the firewall to have the line flared and a 12mm flarenut to attach it to the GSR.

both of them are already 1" MC's. in terms of USDM, any Integra that has ABS has a 1" MC.
