Been researching a stage 2 brake upgrades for a CRX for light track, Auto X, and daily driver use. Found out about the Legend/Cooper upgrade for the Integra front brakes, and the RSX/Si upgrade for the 92-95 Civic rear brakes. From what I have read this should work on a CRX. This is a list of parts I think I will need. If you know the year(s) of the car and model(s), part numbers, have any suggestions on brands please help me out.

Any help?

 

Check this link out. Also the 90-91 EX 15/16 master is a direct bolt on, no line bending.

Why the Integra Master Cylinder though? That is a 1" bore and fairly large. I went with a 15/16" from a 90-91 Civic EX four door which is direct bolt on.

For the rears I went with DA rear arms, which is more than enough for my application. How much larger are the Civic Si Rotors vs the DA rotors?

 

91 civic ex 15/16" bore $ 36.44 It's direct bolt on to the 91 booster
The rotors are from a 07 Mini Cooper non s
But u got to make sure u have the 262mm knuckles that's the part I'm at right now I have 242mm need to figure out what cars will be direct bolt-on to upgrade to 262mm some ppl have swapped and had a camber problem because some are a hair longer creating a problem
