Sup guys, heres the update. I went ahead and dropped the rear trailing arms and installed the gsr rear arms. Also went ahead and had all the rotors cut (front and rear) and i installed the front control arms. All brake pads are new and everything is in and all lines bled. I have been adjusting to the feel of the gsr front and rear brakes and they feel great with the ex master cylinder. BTW i have a 2000 civic with a b16. I still think that I am going to have to change the 3030 prop valve considering i can tell that the front brakes are taking most the power until i finally apply full pedal pressure. I am also looking to find a master cylinder other than the gsr. The GSR set i got are all from a 97 integra. hit me up with some knowledge
