When setting up with an adjustable proportioning valve how many do I need?
I will not be using a stock distribution block right?
Ive never set one up before and Im just trying to figure it out.

Also Who makes the best line locks, I've got one recomendation for Biondo but does anyone else have any opinions?

All you need is one proportioming valve for the rear brakes. You adjust it to stop the rear wheels from locking up prior to the front. If the rear locks first the back end of the car will try to pass the front end. I have a hurst line lock no problems with it. The line lock is only used to help hold you in the box on a burnout.
