For the front use Integra Type R calipers with Mini Cooper rotors. For the rear use RSX Type S rear calipers and EP3 rotors.

I ordered my "kits" from ProParts on both previous occasions:
ProParts USA Integra Brake Kit Upgrade - ProParts USA - Low Price Performance Aftermarket Car Accessories - Brakes | Shocks | Springs | Intakes and More!
I already had a custom made 12in Diameter
Rear Rotor with slotted pattern "copying" Brembo type 3 so it will match the front rotor
(someday when I finally have the budget to do the front Brembo conversion)

Here are some of the pictures (notice the size of the rotor):

The next step will be the 5 lug conversion.
I know Kuo's garage make a conversion kit,
but their bearing is NOT OEM bearing,
I worry if someday I need new bearing, it would be hard to find replacement
if it is not OEM...

so I am going to go OEM route using
Honda CR-Z Rear Hub/Bearing and Front Hub/Bearing.

I will also need much bigger wheel to fit the "planned" 380mm front rotor,
my current 18in wheel would not fit, I need 19in
and I need to finish all this conversion asap,
at least in about 5,000 miles from now
since my Michelin Pilot Super Sports tire are worn out and
probably only have 5,000 miles in life...

I already bought 1 wheel for Fitment purpose (custom rotor hat, and caliper bracket),
it is the Honda Accord HFP 19in wheel.
I choose these wheel because I really like the OEM Honda Look:

gotcha, the EP3 rear rotor is 260 mm so roughly 10.25 in -- custom pieces are always nice but more expensive than something OEM that can be taken off the shelf lol, much respect for the mods you're doing

Alpina, dont get me wrong, a bigass rotor with an even bigger caliper is a thing of beauty, but I come from function>form

I understand it is important to have a one-off car, but just keep in mind, the Fit does not in any way require the brakes of a car twice its weight and have 4 times the power lol

That said, it is your car and I respect your decision to do whatever you want as it is indeed YOUR car and not mine.

PS if you get a 6 piston caliper on the Fit, you best take some damn pictures, that crap would look beautiful!

My JDM Honda Civic FD2 Type R Brake Master Cylinder arrived today,

UNFORTUNATELY...
they use a 13/16in Master Cylinder,
although they are a bit improvement against our standard 3/4in master cylinder
but they are NOT a 1in Master Cylinder as I had expected it to be...
so...
this is NOT good...
Most likely I need to buy J's Racing Master Cylinder...

Man that sucks. The Integra/RSX master cylinder was 15/16. I know the Accord Crosstour/TL/RL master cylinder is 1 inch bore. OEM Honda and something you can get stateside easily, even re-manufactured.

Yes, I had done some research long time ago,
and those Master Cylinder from other Honda,
either have different mounting
bolt pattern to the brake booster,
or different stroke length
or different outlet diameter.

Even the Pre VSA Honda Fit GE and the VSA Honda Fit GE had different outlet diameter.

Since the J's Racing Master Cylinder and the Honda Civic Type R FD2 look similar, I thought they are both the same thing.

but Thanks for the info, I will try to look into the car you mention above,
maybe I am lucky and can get it from the car you mention above.
Thanks again

Ok,

I found the solution,
it will be Honda CR-V year 2005-2006 with VSA Brake Master Cylinder !
It have 1in brake master cylinder with 12mm x 1mm BBL Outlet and dual reservoir input,
plus the flange bolt pattern is correct too.
the only thing different is the Push Rod Depth on the CR-Z is 2.42" and
the Fit is 2.25" which mean 0.17in or 4.3mm different,...
I think I can compensate this on the brake pedal push rood setting...
hopefully...

of course I had to modify the brake line arrangement too, but this is not a problem,
I am prepared for doing this on the JDM Civic FD2 type R anyway,
even the J's racing master cylinder (JDM Fit) are different in brake line arrangement...

The Part Number for the CR-V Brake Master Cylinder are 46100-S9A-A62 !!!


Here are the Centric Equivalent Part# 130.40061 for the CR-V





and here are the Centric Equivalent Part# 130.40077 for USDM Honda Fit GE:

Moving forward with this project (very slowly hahaha)...

I took out the rear hub/bearing assembly to change the wheel stud
with ARP longer wheel stud.

Here is the pictures of the hub assy with standard wheel stud:

I put the hub on vise (correctly position so no surface touch the bearing),
then I hammer out the old stud from the hub.

To install longer ARP wheel stud, I need to use the bolt as spacer,
before the wheel stud installer tool:
by the way, notice the hub assy below are much cleaner then the pictures above,
cause I use steel wire to clean the rust...

Then put the stud installer tool on top of the spacer bolt:

and last, put an open ended nut to drive the stud in:

Oh, don't forget to use Anti Seize on the area where the stud touch the
hub.

and last, drive the nut using Impact Tools:

I am planning to buy the JDM Integra DC5 Type R "RED" Caliper asap so I can finish this rear axle conversion...
hopefully within the next few months

Hi Racer986jec,
Thanks for your offer,
but I plan to buy a new rear caliper simply because it came painted RED from Honda, so I don't have to repaint it again...
if I buy used one most likely it had scratch... or I need to rebuild the seal...
and that require me to buy special tools to rebuild the seal so it will end up costing more

Yesterday, I was about to install back the rear hub onto the rear axle,
take notice the rear hub now have the longer and stronger ARP stud,
but then I see that I need to install the MODIFIED Rear Splash Guard first
because I need it (at least the center bowl part) to protect the rear speed sensor:










on this pictures you will see the speed sensor protrude on the top of the
bearing...
and it is UNPROTECTED unless I install the bowl part of the splash guard:



so I need to drill the tack weld to separate the 2 piece splash guard:





then I found out that it had rust on the back side of the bowl,
so I decide to paint it. first sanded it, then primer paint then top coat:










the pictures above is after painting, it look black, the above pictures
looks like it still have rust but it is just reflection since the paint is not
dry yet and very shiny.
later I will paint the inside area of the bowl too...

Hello Kenny,
I got those rear axle from Japan, my friend who used to do business there
imported it for me. but I don't think he is doing that business in Japan anymore.
You can always buy the CR-Z rear axle here but you have to change to 5 bolt wheel pattern...

or you can buy this parts from JapanParts.com as brand new OEM Honda Parts but it will be quite expensive including shipping
