First, could someone be kind enough to verify these part #'s:


'99 Integra RS proportioning valve - 46210-S04-951

'99 Civic SI proportioning valve - 46210-S04-902

Ok, if these are supposedly both 40/40 valves, then what the heck does the 40 stand for? Are they the same bias? I can't see the same valve being typical among so many different models between several generations of civics and integras as I would expect the bias to be extremely critical and dependant upon different variables such as suspension setup, spring rate, weight distribution, ect.
