As already said, its a law in australia. brake bias cannot be adjustable while the car is in motion. Hence it being placed in the engine bay where nobody is going to defect/ticket me for it.
If you have to keep ABS, you'll probably need to put the valve before the ABS pump. Pretty sure both tilton and wilwood say they aren't compatible with ABS systems. Something about the pressure modulation from the pump can cause damage to the proportioning valve.

Part of me still wants the ABS, Part of me doesn't care. Right now, the pump is disconnected, and relays are all removed, so the ABS isn't working, and I honstly don't see a difference. When I do a bunch of work this winter, with the motor out of the car, I may just delete it altogether and re plumb it.Leave a comment:

I'd say after? Not sure. Why not remove it?

I want to put a proportioning valve on mine also, but I'm still running ABS, and I am not sure if I should put it before or after the pump.....Leave a comment:

Why does it have to be in the bay if it is street driven? I was hoping to put mine on the trans tunnel too

I put my proportioning valve in the engine bay because the car is still street driven, so you can't have it adjustable from within the car when running. Im going to relocate it inside now im putting the cage and stuff into the car. Probably going to mount it on the trans tunnel so it's in easy reach.

This is all great info I appreciate it, so balance bar adjust and manual prop valve? Do any of you have pictures of your brake line set up? I'm very interested.

True - oops yes I do have balance bar set a bit to front after road testLeave a comment:

inline valves are basically just pressure regulators. So you use the balance bar on the pedal box to set your bias, front to rear, then fine tune with a proportioning valve. Wilwood make a M10x1.0 one to fit bmw brake lines that will go right in.Leave a comment:

I installed both Wilwood proportioning valve and cable adjuster.
Clearanced the garagistic bracket as shown in other post. Set balance bar 'neutral'.
My brake set up is E36 frnt , E 30M3 rear. I replaced the factory proportioning valve to rear brakes with the Wilwood adj. Installed the proportioning valve to dial in the f/r bias and use the cable to tune. I'm planning to install larger 330 frnt brakes so resetting bias is easier

With the remote adjuster you will need to modify the garagistic bracket slightly: http://www.r3vlimited.com/board/showthread.php?t=394077Leave a comment:

Remote balance bar adjuster?? Never new that existed. Is it like linkage or something??

It already comes with a balance bar, so if you're concerned about access, get a remote balance bar adjuster and mount it in a more convenient area.
As a part of installing the setup into your car, it's likely you will have to adjust the master cylinder input rods after you plumb the system in, and dial in the balance bar adjustment.Leave a comment:
