i have rear disc brakes on a 97 cx EK hatchback.

i have tried to find out which proportioning valve to get.....


now i've been reading a lot of stories/myths about how 1999/2000 Civic SI proportioning valves are the same as the 1996-2000 Civic Hatch prop. valves....
is this true?


Is the 99-00 SI prop. valve actually better?
or is my stock 96-00 civic hatch prop. valve the same thing?
