so i pulled a fastbrakes 11" kit off a shell and went ahead and pulled the prop valve cause i wasnt quite sure about it. it says "25/30" on it just like the stock one but the bottom portion is actually stamped "40" rather than 30. anybody know what this is all about? the guy that built up the shell works at a shop and didi the brake setup himself including the da booster/master cylinder swap. just wondering if anyone knows why he would have swapped the bottom portion to a 40 in stead of a 30?

 

what did the guy who put it together say?

 

Just get a 40/40 off a dc integra will save you time and trouble.

 

cant get a hold of the guy that put it together. talked to him on the phone before i pulled the parts but i delt with a buddy of his in person. ya i am gonna be running a 40/40 cause ill be running rear disks, he was running the 11" set up front with drums in the back, which i assume is why he ran a "custom" prop valve.
