I'm about to swap the rear discs from a crx si over into my 90 sedan lx and i'm wondering about the prop. valve. I have the option of just taking the one off the crx and using that, but wonder how that might affect fluid flow to my front brakes. The fronts are from a 93 gsr and I think are a good bit larger than those on the front of a crx si (not totally sure though, can anyone verify?). I guess my question is, would the crx prop. valve be sufficient with this setup or should I get the 93 integra unit?
