My JDM DISK BRAKE RS Rear Axle conversion
 

My JDM RS Rear Axle with Disk Brake just arrive about an hour ago.

They are practically BRAND NEW, coming from a 2012 RS model car that had been subjected
to flood and thus cannot be sold as complete car anymore.

but since they are basically just steel part and painted, there are no corrosion damage.
the seller said that this is from FRESH WATER Flood which mean not the Japan Tsunami
but the Thailand Flood that happened last year.
if this is electronic parts, I would NOT buy it, but since this is Mechanical Part,
I am ready to take the risk and turn out the reward is good for me :)

I just check the movement of the hub and it seemed that the bearing is OK,
but if worst came to worst, I can just replace the bearing and get it from US Dealer
because the part number for that bearing is available here.

The next few weeks will be FUN for me :)

Here are the pictures:

Sexy!!!!!!!!!!!

This is an AWESOME project thread that I look forward to updates on!!!

If rear axle members are available like this... should open up some awesome project ability to Noth America continent spec'd cars :D Who want's to research what a GD4 drive train will cost :p

^^^4WD.... now that would be a super epic build... http://www.crzforum.com/forum/images/smilies2/drool.gif

The rear arm looks beautiful Alpina! Congrats! :thumbups:
Looking forward to your future updates. :vtec:

Thank You Wafulz and Thank You TPColgett,

Wafulz, if you have free time, please come by to my place
so you can check it yourself :)

TPColgett,
is GD4 a 4wd version of GD fit ?
what is a GD4? Pardon my ignorance but I am really
not familiar with any Honda Fit model before I bought one 3 months ago :p

Thanks FitStir,

My update would be slow though hahaha
I am following your method of modification :)

I had ordered from Amazon a caliper paint.
I am going to paint this rear caliper yellow,
because in the future I plan to have front big brake kit
with yellow caliper, but that got to wait because
my cash flow rule from my wife again just kick in hahaha
(like a VTEC kick in in high rpm hahaha)...

I also need to dissamble the rotor so I can see the bearing,
just want to make sure.
I also need to buy Progress rear sway bar so when install this
rear axle it will be at the same time.

Also need to buy Spoon Rigid Collar for the rear axle bolt
just to make sure it will be more rigid at the axle joint

last need to buy Mugen JDM RS Brake line (for disk brake car),
and it have 6 BRAKE LINES !!! 4 for rear and 2 for front.

I check the CRZ brake line available in US and they only have 4 lines on their kit. but if you do a rear disk brake conversion on a HOnda Fit
you would need 4 brake line just for the rear axle alone...
so remember if you in the future decide to buy a rear disk brake upgrade kit for your car,
get the JDM brake line kit which had 6 lines total.
Don't buy US CRZ goodridge or Fit kit which only have 4 lines in total.

Shhhh... it's my secret... :D :D :D lol.. if people knew how long I've been sitting on some parts I'd get banned.:rotfl::rotfl::rotfl:

Great info!!!!
If I go the flange route it's just a CRZ brakeline swap, but if I get the JDM rear I need the Mugen RS (GE8)lines... I didn't know that... you've done quite a bit of research/modding in only 3 months. :thumbups:

Ill be there sunday after noon :)


Brake lines i just got the 4pc set Owell :) when the time comes ill will just buy the 6pc :)



As for rear sway bar ALPINA my friend gots a cusco one siting around text me if u want it :)

Hi FitStir,

no, if you go Flange Route,
you also need JDM Rear lines.

why because there are 2 lines that connect the steel tube brake line at
the joint of the rear axle on you current drum brake set up,
plus
then you need another brake line to connect (after using male to male adaptor) from the current line that enter your brake drum to your new
caliper.

so you need the JDM lines whther you are doing swap like me or
doing the bracket/flange route.
if you just buy 4 lines, then you are still having rubber line on your rear brake system.
and your pedal will still be a bit spongy because of this.

check on my picture #7 from top,
you will see another brake line near the bolt that connect the axle to the chassis.
that one is already on our drum brake fit now.

Hi Wafulz,

the cusco rear sway bar is only 16mm...
I think it is better to buy the thicker Progress sway bar for this rear axle.
especially since I heard this disk brake rear axle is heavier then the drum brake rear axle,
so I think it need more stiffness of swaybar to control it better.

Haha and one that would be $$$$, maybe $$$$$ I'm SURE, especially since they made like only 80+ Whp to start, and if your going to go to all the trouble and $, your going to want to double if not tripple that output :vtec:

Wafulz:If you don't take up this offer I may try to convince the HellaFit crew to road trip out and do so!!!

BMW ALPINA: You are correct, the GD3 is the chassis code for the GD cars from 2007-2008 received here in the North American market (as well as several other markets overseas.) The GD4 is the chassis code of a Fit model sold in Japan and I THINK Russia, ONLY that has a 4wd drive train :vtec::vtec::vtec:

:rotfl::rotfl::rotfl::rotfl: I COMPLETELY know this situation.

ANY car project, you either have the time but not the $, or the $ and not the time OR Significant other approval to carry it through to completeion :p

Oh really now... :iough: :p


You can say that again!!! I am always SUPER excited to see new members take the plunge and take on exciting projects, especially when they seem to have BMW ALPINA's budget AND enthusiasm :bowdown: :popc:

ahh i c otay no wonder he has not sold i guess its good for a base model

if you just buy 4 lines, then you are still having rubber line on your rear brake system.
and your pedal will still be a bit spongy because of this.

check on my picture #7 from top,
you will see another brake line near the bolt that connect the axle to the chassis.
that one is already on our drum brake fit now.


i just seen that extra line i was like wtf that lol : /

u got link for 6 pcs kit ?

This is awesome, in for results :popc:

Hello,
this is the link for 6 piece kit made by Goodrige for Japan JDM model,
Goodridge (

but I think the seller is from Hong Kong although he/she advertise on Yahoo Japan... so I am not too sure about buying from this vendor.

There is also another one (Goodridge) on eBay UK:
but it is EXPENSIVE:
Goodridge Honda Jazz (Japan Spec Rear Disc) Braided Brake Kit Lines Hoses | eBay

but on this UK vendor you can choose THE COLOR of the outer jacket !!! :)


Still, I think I will buy the Mugen one because
the Mugen one should had the exact factory style mounting
and on the rear axle there are several unique mounting that might not
be utilized if you used Goodridge (this is just my guess).
Here are the link for the Mugen one:
Amazon.co.jp: ‚±‚¿‚ç‚à‚Ç‚¤‚¼: –³ŒÀ ƒ}ƒCƒNƒ�ƒ�ƒbƒVƒ…ƒuƒŒ�[ƒLƒ‰ƒCƒ“�yƒŠƒAƒfƒBƒXƒNƒuƒŒ�[ƒLŽÔ�z 46400-XLF-K1S0 ƒzƒ“ƒ_ GE6/GE7/GE8/GE9

Thanks Wanderer,
but it will take a long time before I can complete this :)

Thanks TPColgett,
but the truth is I am just an old person who used to like driving fast,
and only wish I could still be driving fast
(but realistically I cannot and should not do that anymore),

but
now just a POSER who only do this rear brake modification for LOOKS :p

what I have now is called, Mid Life Crisis hahaha

alltrac, said he used the Goodridge CR-Z SS lines when he used his flange/brackets to do his rear disc setup... there might be 6 lines in that kit? :confused:

No hehehe :)

because as soon as I read that post from Alltrac,
I immediately try to find out about the CR-Z kit available here in US,
and I found out that
all of them stated only have 4 lines !!!

I guess the maker of the kits do not looks at the rubber hose
near the axle bolt mounting :)

and they thought the only hose at the rear are the one that connect
to the rear disk brake on CR-Z.

that is why those brake kit for CR-Z (US vendor one) are cheaper
compare to the Fit with 6 line.

if you check, Mugen also offer 4 line kit (cheaper) for Honda Fit with Drum brake the 2 for front and 2 for the one that near the axle bolt.

For Your Information,
you can always buy directly from Goodridge UK !
I use to buy direct from them when I have my motorcycle racing team.
Problem is you had to know what kind of hose, type of fitting, banjo bolt type and diameter etc etc... also length of each hose.

or you send them your stock factory brake hose sample and they will COPY it using Goodridge material for you.

the color of the outer jacket is also amazing, there is the carbon color, but what I used to like is the red color
in combination with the Kevlar Jacket (not stainless steel braided but KEVLAR).

They have several kind of hose size and material. I used to buy their smallest diameter hose with Kevlar jacket which provide the Stiffest pedal feel/pressure while also very lightweight.
I also use the stainless steel fitting because they look better then the zinc plated one...
but that was like 10 years ago... and I used to buy in large quantity so
I got IMPORTER PRICE discount !!!
and now I am too lazy to spec out my brake line directly with Goodridge UK...
I am just going to buy standard mugen one... hahaha

Maybe they bypassed them... who knows.. they never really detailed it..

Anyway... don't want to take away from this epic thread. Congrats on the rear axle, and post up pics of the install.

oh no,
it cannot be bypassed because otherwise you will need
a meter long brake hose from the connection before the rear axle bolt
up to the rear disk brake.

right now, from the front master brake cylinder they use small metal pipe
up to before rear axle bolt.
since the axle move up and down they need rubber hose that is flexible.
after that rubber hose they again use solid pipe to connect to
rear drum brake.
so if you buy the kit with the mounting bracket you will need a male to male adaptor which you then connect to another short brake line (maybe 30cm long) and this connect to rear brake caliper.

yes, if you want you can order a long brake hose to connect from
before rear axle up to rear caliper directly but it is going to be more expensive because it should be about at least 1 meter long each side, so 2 meter both side.

and you will waste the steel pipe hose fitting that is already there that used to connect to the drum brake.

Today, I make my first mistake...

I decided to take out the caliper (in preparation to paint it as soon as my paint bought from Amazon arrive),
and the rubber hose (so I can install a ss brake line later),
and then wash my rear axle.
so later I can see if there any scratch on the rear axle and I will paint it to make sure
it will not rust later.

problem is when I try to take out the rubber brake hose, I don't have the correct flared wrench, and I don't know that you had to use this kind of wrench.
so I just used regular open wrench and I end up stripping all the nut...
some of them are so bad, I just cut the steel brake pipe to take it out...
I will post pictures later...
now, I got to order the replacement steel brake pipe from Japan .... oh well...

In the past, I had change several stainless steel brake line on European Car, and I don't recall that
I need to use special flared wrenches... (but this was like almost 20 years ago hahaha)...

and when I change ss brake lines on motorcycles, I never need this flared wrench because with motorcycles is all banjo bolt and we can use socket wrenches...

oh well, another lesson learned today...

I am lucky that the steel pipe that I broke were only the 2 short one on the rear axle
and not the long one from the front of the master cylinder to the rear axle...

Bring your JDM lines to the car parts store, they can match the connectors adn you can buy a cheap pipe bender for brake lines and a few feet of brake line ALL this for less then $40

screw ordering expensive pre-bent parts. DIY!!

I see how your rotor is after viewing this thread. I will see what I can come up with, as I am going to the junkyard in the morning (its nearly 1:30 am)

If we dont find the motor and tranny we are looking for, perhaps I will grab a few rotors as I am eventually going rear disc, but I think I am going to match front and back from an older integra or civic for teh sake of huge aftermarket fitment and kits available

actually the price for the 2 brake pipe from Honda in Japan is only around $18 USD !!!
yes they are very cheap,
and maybe with shipping they will cost me around $40...
so I am lucky that they are cheap... :)

My Impact Screwdriver arrive so...
 

My Impact Screwdriver bought from Amazon just arrive so I immediately use it to take off my rotors:
Attachment 19900


but the quality of the impact bits are BAD, and I manage to broke one shorter "+" bits already... luckily it came with another one (longer) "+" bits.
Those screw were TIGHT !

as soon as I have time to buy some Wire Brush, I will clean the rust and paint it :)

Mystery Parts ???
 

Here are one Mystery Parts that I took off from the rear axle because our USDM car don't have this parts...

It's look like some kind of Vehicle Height sensor ???

hmmm, perhaps the JDM car had self leveling headlights???

anybody knew what this part for?




Attachment 19899

Could be a sensor for the VSA system.

VSA system?

I don't think so,
Why VSA system need to know the height of the car?
because on this sensor, one leg (the silver ball joint) is attached to the rear axle,
and I am pretty sure the other leg/bracket (the black plate one) will attached to the chassis.
so it should measure the movement of the rear axle (up down) relative to the chassis...

If I am not mistaken,
VSA means Vehicle Stability A, Right?
(I don't know what the A means hahaha)...
is A for assist ?

Great build going on BMW I will follow it for sure.I had my midlife crisis a while back with my 2011 Mustang 5.0

I went nuts and while it was a blast I sold it last year and got my Fit.
Did you win the Powerball lol or are you one of those Hedge fund guys loaded with moola:)

Good luck with the swap and thanks for sharing the progress with us.

Thanks Zilla8,
I wish I win the Powerball so I can complete all this upgrade faster :p
I plan to keep my (this) Honda Fit FOREVER, because this car has sentimental value for me and my family :)
that is why I try to do my best in modifying this car. :)

wire brush as much as you can and then use this.

Hi,
We have same thing in our mind :)
I am currently waiting for VHT Yellow Color paint for my caliper,
and I am also going to paint my rotor with Black VHT but
I need to order it later, cause I forgot to order it when I order my yellow VHT.

Thanks :)

Do you have an oven where you can cure your parts?
Its been awhile since ive done it but I remember that this stuff is excellent on brake parts once you cure it.

If someone here interested in getting the JDM Disk Brake Rear Axle,

I can help,
There is one more complete JDM Rear Axle with disk brake in Japan.
Also victim of Fresh Water Flood
(I guess this must be the Thailand flood because the Tsunami is Salt Water Flood)...

just like mine, it is also in Brand New condition because taken from brand new car that had been victim of flood.

Ready to install, all you need is take out and install 4 bolts, install parking brake,
bleed the brake and you already get Rear Disk Brake.

Later, you can always sell your stock Drum Brake axle to recoup some cost.

The only think that you don't get is the Wheel Sensor, but
you can use your stock rear sensor since the one with this axle had been cut (wire) when they remove it from the car.

All parts are original Honda factory parts and original Honda factory design,
so this is real factory quality. What you get is New (Rear Axle, Rear Rotor, Rear Caliper, Brake Pads, All Brake hose and piping on the axle, Parking brake cabling)

No need to wait for a long time (1 week for shipment from Japan MAX),
no need for any fabrication,
no need to get rebuild/used parts for caliper/rotor,
brake bias is the same since this is factory design.

I can get this one for $1,500 including air freight (piggy backing on my friend air cargo) to my house
and all you need to do is just pick it up at my place, ...
(I paid much higher for mine due to me insisting on getting RS only axle, this one is NOT RS axle,
but other Fit model that have disk brake too, later I realized they are both the same thing,
but have different part number simply because different in rear spring rate!)

I can help you ship it to your location but I would prefer you to pick it up at my place,
or you can have Fedex/UPS pick it up at my place in Anaheim if you have your own Fedex/UPS account.

Ive seen used autolevelling computers on yahoo auctions japan. Not sure if thats vsa or not

Hi,
Yes, I have an oven, but it is cooking oven,
and my wife NEVER used it for cooking but I once used it for painting
bracket for my Honda Accord Exhaust Tips mod with high temp paint :)




I just done some reading about VSA and from many literature and Honda Press Release/article, it seemed that the VSA run solely from input of
each wheel sensor but none mention about VSA connected with self leveling sensor...

I also think it is more accurate to measure the level of friction on rear wheel from wheel sensor than relying on the height position of the rear axle of the car, because sensor on wheel measure real time and dependent on road grip/surface type,...

or I do read/see something about active Aero,...
is this had something to do with that?
anybody know about active aero? is the bumper had aero/spoiler that
can be move with some kind of servo or motor?

I am just guessing though,... I still have no clue on what this sensor do...
but I just check again from the pictures of our car and our USDM car definitely do not have this sensor eventhough we have VSA...

what I am happy with VSA is now we don't need to have brake proportioning valve anymore on our car,
so if we change from rear drum to disk,
the car will automatically adjust the pressure going to EACH rear wheel based on the each wheel sensor input !

of course there is limit of what VSA can do,
if we put crazy big brake in the rear, it still will be bad for the car brake bias and will affect the handling...
hmmm
talking about correct brake bias,
I already had complete idea on what kind of custom rear big brake kit
that can balance the front big brake kit that I had in my mind :)
but that is going to wait a bit :)

as far as i know, the active aero refers to the front spoiler bumpers side LED lights.

Thanks for posting that ECU picture here

Hmmmm,,,...
Koito usually produced lighting/lamp related equipment...
so most likely this is for self leveling headlights... or that LED light...

but I think, given it's price,
that there is no way a Honda Fit,
even RS model had a fancy self leveling active suspension hahaha
