4 Piston DynaPro caliper upgrade for almost ALL Big Brake Kits
<p>I wonder what Jaguar's electrically actuated parking brake weighs.</p>

And if you are some other company that sells a Wilwood rear caliper set-up and add a parking brake it increases the cost by about about 41% (still want, though).
What I am psyched about is this is being worked up to keep a good F/R bias balance.

No further details on products for the rear for the time being. Naturally, lots of track testing before anything gets a green light, I don't want to make any hard promises on a configuration that may change during development.
Upgrade to DynaPro 4-piston fronts!

<p>So I stuck some BP-10 7112 in my dynapros last night, and the hole where you put the cotter pin is way bigger than on the dynalite, do we need a bigger cotter pin?</p><p>This picture might explain it:</p><p>
</p><p>See how the cotter pin like fell all the way through?</p>

Doesn't have to be that big. Looks like a 6-32 or 8-32 would fit. Drywall anchor screw size, long enough and usually pan head.
I'm going to do something like that. I don't want a bagillion cotter pins.

For 7112 in the Dynapro you need 2 cotter pins per caliper, in the two outside holes, no use for the center hole as on the Dynapro that hole is for an optional bridge bolt, not a cotter pin. The Dynapro doesn't have pad keepers on the bottom, so the height of the pad in the caliper is regulated by the pins alone, thus the need for two of them.

Could I drill out 7112 center hole for a bridge bolt?
<br />Only asking because G is giving me a set of 7112 bp-10s and they don't have the 3 hole.

The bridge bolt is not intended as a slider pin, so while you might be able to drill out the backing plate for a bridge bolt to fit through, that doesn't satisfy the need for locating pins for the pads to slide on.
The ability to run some 7112 pads in the Dynapro is a big deal for expensive/top-tier compounds that aren't available on 7812-specific backing plates (Dynapro uses 7812). A BP-10 is like, $35-$45, and available in both 7112 and 7812. Really no reason to try to mickey-mouse the 7112 version into working in that case.

Except these pads were free, and free is cheaper than $35.
I can't argue with that
What's the bridge bolt for
"Bridges" the gap between the two halves of the caliper. Adds rigidity. It's a bit of an afterthought on the DynaPro and not very necessary IMO. It's already significantly more rigid than say, the Dynalite.

<p>Question for someone who had DTC-60 7112's in their hands.</p><p>Looking at hawk pictures for the DTC-60 in 7112 I don't see the 3 holes. Is this an error, or is the DTC-60 one of the pads that doesn't have the 3 hole backing.</p><p><img src="http://cimg3.ibsrv.net/gimg/www.miataturbo.net-vbulletin/792x792/80-hb540_d90676d618d1826fcc9da9e61c5ae50646459ee2.jpg " title="" /><br /><br /> </p>

PFC01 in the rear. Get the standard 1.8 rear pads and with a little backing plate shaving they can fit the sport calipers. I don't have pics of the process since none of us run the sport rear caliper here, but lots of guys have done it.

B) But, if you're a big fan of the Quick-E-Clip like me, a little notching of the backing plate will make everything clear the E-Clip's pins in the center and you're good to go.
Here's a pic with the standard 7112 PFC pad on top, and the same pad modified below it. I got a little fancy with the carbide grinder on these, but three simple straight cuts will do the job, since you don't need any of that center portion:

it's not uncommon to have teams File the backing plates. it happens a lot with making bridge bolt calipers work with non bridge bolt pads. Do use a file to do this, and not a grinder. the vibrations from the grinder could damage the brittle nature of any race pad. if you where staying on a budget that would be the one i would choose. after that i would recommend just swapping out to a v8 roadsters front kit, and 1.8l rear caliper + sport rotor kit.

Johnny (OGRacing) is our distributor for PFC pads and the one I consulted when originally looking for a PFC option for the Dynapro. Grinding the backing plate to clear was his suggestion and also got the OK from a PFC engineer.
