Thank you for the help guys

I don't quite understand the prop valve. If my car doesn't have ABS and I install a prop valve, how do I increase the rear bias? The valve can't dial in any more than the factory bias.

Under heavy braking the factory valve cuts some of the pressure to the rear. With the adjustable you get rid of the prop valve, and have an adjustable valve going to the rear so with the valve full open you have full pressure going to the rear. Front will always have full pressure. You can dial back the rear pressure with the rear valve is full pressure is too much.

With 225 200TW tires and xp8s all around I've been running the valve open street, track, autox I never seem to get rear lock up. Now I'm running Cobalt XR3/XR4 and still running it full open. I could've just removed the proportioning valve and ran 2 unions the way I have it adjusted and saved myself $50 lol. But it's nice to have incase track conditions change and I start having the rears lock up.

I don't think PFC does that plate. Goodwin ground the tabs off a set of 7112's or something for the Goodwin brake kit we used at MRLS on our ND.

Tim I run the same pads but on OEM NB8B calipers and DBA T3 rotors and have not experienced what you are describing. Feedback by another driver were positive about them as well, however the brake setup could be improved by a manual bias valve as the rears were locking up too early (at Morgan Park).

Let me know if you want to drive mine.

Thanks for all your responses guys

I was hoping I had just missed something on the pad diagram, but I guess not :(

Obviously count this as an expression of interest for that pad shape

What's the minimum thickness for getting rotors turned again?

What kind of evil bastard puts those phillips head bolts in? The person who thought that was ever a good idea needs to be drug out into the street and shot.

First I would just like to say maybe my new brakes and pads felt quite horrible because the prop valve was set to all the way "less brake"... It was one of those days.

Just wondering if anyone who is more cleverer than I could perhaps suggest if 7895 | PFC Brakes - Performance Friction these pfc pads would fit the wilwood 7912. Im guessing since John has already said there is no pad for these calipers I'm going to be out of luck, but no point in dying wondering.

I saw nothing for pricing in my PFC price guide. I shot an email to PFC to see if it's an actual part number.

Wilwood's 7816 is the same as its 7812 only with thicker pad material. Both pads are used in their dynapro caliper line; the 7816's in the radial mounts (which are wider) and the 7812 in the lug mounts. Therefore you can run a 7812 in a radial mount dynapro 4, you would just have the same pad thickness as everyone else instead of the thicker 7912 pad.

The Wilwood schemas disagree.
