Tackling things little by little. Worked on the RH side.
Completely disassemble to bare axle and spindle.
Install axle adapter
Notice provision for wheel speed sensor, one of the absolute requirements I set for myself was making sure everything was ABS friendly for those meticulous about their builds and wanted to keep the system. This requires near perfect match of total piston area between front and rear, and correct brake bias for the system as a whole.
Still waiting on my brake lines, and have to design a mount for the hose.
In the next week I'll also have to go back in and add some shims to line up rotor to caliper(pretty standard in prototype stages. IE rear adapter needs roughly a 0.5mm shim). Design will be updated once I confirm more precision fitment.
Also moving onto wiring everything up with the control unit. One of the more costly additions to the kit is actually the EPB retrofit kit which consists of 2x caliper, pads, wiring, control module, and switch.
As for the modular EPB mount, the modularity really only applies to 0.05% of 80 owners with heavily modified rear ends, or willing to fabricate. For the rest of us, the parking brake caliper gets mounted 180 degrees from main caliper. This is due to clearance with the track mount on the right hand side. Because of this a 1.75"-2.25" bump stop spacer is required, need to confirm after cycling. Most of us are running lifts and bigger tires so likely already running a 2"+ spacer.

Once I finish everything off and put in some miles happy to take everyone out for a test ride.

I think I read min 2400lb clamping force. Definitely not designed to be activated while vehicle is in motion

SILVER Star
Maybe, but so does a bread bag clip.
Is there going to be an interference problem on the rear without 2” lift? Will I be able to utilize full travel? I was not aware of this and I have already ordered. I am keeping stock suspension height.

I'll confirm this week after cycling the suspension without the springs on. 1.75" is me playing it quite safe. If its a concern for some, I could add another 15 degrees of rotation so caliper sits further away at 195 degrees from main caliper.
Important for me. I do not want a lift or limited suspension. Thanks

It's unfortunate the track bar frame-side mount get's in the way on the right hand side of the axle. Will be adding another 15-30 degrees rotation of the EPB to suit stock height 80's to avoid needing a bump stop extension. Honestly didn't think people with stock height 80's would be interested in this, but happy to take care of everyone.
Extra 2 radial provisions should allow for roughly -30 and -45 degree locations from rear(7:30 and 8:30 if viewing right hand side of axle) for the EPB. Previous limit was about -15.
For those who are running bigger tires and suspension lift a billet bump stop extension will be provided, because why not. 55mm

That’s great. Thanks. We all need good brakes even if only a commuter car.

Been out with the flu for the past week, and first day back on this.
One issue with the rear lines was how close the 90 degree bend was to the shocks. Because Wilwood uses 1/8 npt on their calipers I've always disliked using 90 degree fittings and much prefer a 1/8 npt to AN adapter and use a swivel fitting on the line itself.
Unfortunately this causes a lot of stack height.
For a few days I went back and forth discussing with Hel Performance on solutions. In the end we agreed resorting to 90 degree 1/8 NPT to AN adapter was simplest solution. Sorry for camera missing focus...
I've gone back and forth and disassembled and reassembled the front and rear hubs more times than I care to count. But only thing left is to flush the brake fluid and wire the EPB. Ideally most should install the control module under passenger seat, but I've got one of my 3 amps and DSP controller under there and my AC unit for non-working center console fridge under my driver seat. Will likely just mount to where parking brake lever currently sits. Hopefully get to bedding in the pads this weekend.

As I seem to be bad at what updates are shared where here's the brake line mount I came up with since this exists on the factory brake adapter/backing plate. Opted to go stainless.
Bonus:
This project wasn't without it's trials and tribulations.

The updates please. Can’t wait.
Just a friendly suggestion, go with a more standard font. This one is damn near impossible to read. I wouldn't use it for anything, including your logo.
Been lurking in this thread. Very interested in this project, although the cost may be prohibitive for me.
As long as we're all piling on... yep. Reading that font is pure hell.
It might be fine with perfect vision. My astigmatism turns all the letters into a collection of indistinguishable boxes.

Dang, tough crowd. More comments about a font than the product itself this last page. Anyways, already been noted and planned to update.
(1/2) Now back to topic, my OCD took me on a side quest... This bracket replaces the factory parking brake lever. Houses the Wilwood EPB controller module, switch, and my Switch Pros SP9100 control panel. Made from stainless 304.
In my caption I did realize I should have flush mounted the Switch Pros panel, so already sent off a revision to Send Cut Send, and also included laser cut markings for the EPB switch as the Wilwood one comes with a cheap metal sticker.
