OK I got my Maddog mount and it looks like I am still having to do more than just weld it in!
What did you guys do with the Brake Proportioning Valve? Also, how high do I mount this? It looks like it will have to be high to clear the heater pulls? Attached thumbnail(s)

QUOTE I'm going with a bias adjuster somewhere in the cabin. This isn't about bias on a 914. It's about saftey. That valve has nothing to do with bias. A mid engine car has polar moment inertia (think spinning top). It's tough to get it to spin but, when it does... you're screwed. This valve prevents your rears from locking, causing spin in a panic stop. A "Bias Valve" can only "restrict" fluid movement to the rears (you can't really hook it up backward). (IMG:style_emoticons/default/blink.gif) Our rear brakes are small (matched perfectly to the fronts by those dumb guys at the Porsche factory). You want your rears working 100%... 99.9% of the time. The only time you don't want them working is in a panic stop. This is when your pressure regulator kicks in. Another way to look at it is: 70 + 30 = 100% Now... add a bias control valve and give it a turn: 70 + 20 = 90% Give it another turn: 70 + 10 = 80% I'd rather have 100% of my brakes being used when I come into a corner. Especially these brakes. Just say'n. (IMG:style_emoticons/default/biggrin.gif) |
