As I believe to the best of my knowledge...the GSR will bolt up. BUT, you need to reflare the lines b/c the GSR uses ABS.

The only time you need to bend the lines is when you are using an ITR MC/Booster.

This is to the best of my knowledge. Im not 100% sure though.

Where did you get the proportioning valve and how readily availible is it? Im looking for the 90-93 Integra or 92-95 proportioning valve for my setup.
