Manual swap pedal box writeup.

PROTOTYPE

If you’re asking why would you spend a bunch on this vs modifying a wrx or other subaru pedal box? Well here’s a few reasons you may or may not know:

-Wrx/other subie pedals put them all closer to the gas pedal crowding that
-Wrx/other subie pedals are closer to the floor
-Wrx/other subie pedals require modifying the gas pedal to clear the crossover arm from the clutch.
-Wrx/other subie pedals require some sort of extension to meet the upper 2 mount points of the pedal  box or omission of the mount point.
-Wrx/other subie pedals require a pass through the firewall for the studs to mount the clutch master cylinder and rod.


The main advantages to this setup:
-adjustable pedal ratio between ~4.5 and ~6.5
-pedal and parts are bolt on (with the exception of the cutting down the stock brake pedal)
-master cylinder size selection






Parts list required:
-Wilwood master cylinder, standard Subaru is 0.7x so a 0.75” one would be a good baseline
280-12384 0.625”,
280-12385 0.75”,
280-12386 0.8125”,
280-12387 0.875”,
280-12390 0.9375”,
280-12388 1”

I made a bracket to mount 6 summit racing coils to my Svx, one under the air filter, the other where the washer fluid reservoir used to be.

It’s not for everyone but it works and msd coils can be subbed in too so you can get parts on the road wherever you might go.

Takes a set of build your own plug wires from summit and 6 summit coils and the pigtails off the back of the stock coils so it plugs in.

This bolt is installed with the caliper and bracket off.
Then the bracket is slid over the rotor with the caliper and bolted to the knuckle.

This shows the one set of bolts (ignore my nut spacers lol)

You'll need:

——————CALIPERS—————
02-10 VW Toureg
03-10 Porsche Cayenne
05-15 Audi Q7

(I have found car-part.com is the cheapest place to search, its an annoying website but yields the cheapest prices outside of local junkyards)

The calipers should say 17ZL and 17ZR (it’s come to my attention most parts stores show the rotor size, 330mm instead of 17z)
PNs 20.8432.06 and 20.8432.05 (see pictures)
(use these numbers to confirm, there are many calipers that look similar but wont work)


—————-HARDWARE—————-

4x M12-1.75x25 (shave down to 24mm)
(McmasterCarr.com PN 90128A296 - Socket cap style bolt or equivalent)

4x M16-1.5x50
(McmasterCarr.com PN 96144A334 - Socket cap style bolt or equivalent)

Spacers included but if you needed the specs:
14.4mm thk spacer, 16.15mm ~0.75” Id, 25mm od


———————-ROTORS—————-
2008-2014 Lexus Isf rotors (360x30)

Stock brake lines can be used although I would recommend getting stainless braided lines as it improves feel vastly.


NOTE:
If you purchased calipers bare the hardware to mount the pads can be had here:
