Ok, I know this has probably been discussed in many threads before. But, what is the reasoning for replacement of the Prop. valve with the "T" fitting for the rear brakes. Does the prop. valve cause more line pressure to the fronts or the rears when it is operating properly? I want to understand the engineering aspects of this modification.
I will be running "M" calipers with mythical billet hubs in the front and stock 914-4s in the rear. thanks (IMG:http://www.914world.com/bbs2/html/emoticons/unsure.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif) |

Yipes, I've been rolling this way for 14 years... (IMG:http://www.914world.com/bbs2/html/emoticons/ohmy.gif) I've never run into a problem but was never blown away by the brake upgrade. Now I know why -- I'm probably hardly using the rears! I've locked up the fronts maybe twice in that time, I think. Never had a fade problem, though -- which I did with the stock rotors. I drove a 993 with motorsport Brembos a while back. It had a lot more rear-brake bias and that thing was ~amazing~ under braking on the way into turns. Somehow, I don't think my setup will approach that (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) -- but a little better is always, well, great! pete |
