vw rallye/syncro 280mm big rear brake conversion

[bam20v]

hi all

after seeing lots of big front brake conversions
and doing a 325mm one myself
the rear brakes always looked silly
i remembered seeing i think on here a set of rear calipers adapters

so after much headache lol as i couln't find post

have ended up with this
280mm vented rear disc 4 x 100 or 5 x 100 (5 x 100) shown
audi calipers and carriers



had hubs machined so they are 4 x 100 and 5 x 100
cnc'ed brake adapter
also had a set discs changed
so have one set of 4 x 100 discs and one set of 5 x 100 discs
not sure what wheels im going to run
just waiting for 10.9 grade bolts to tighten it all up

This will be my next year upgrade !!!

How much for the brackets?

[yellowslc]

Thanks for keeping this option available. My machinist and I are simply too busy to keep these available.

I have two badass sets of R32 rear calipers if anyone is in need.

Ceramic coated bodies (red)
Teflon coated bores
Ceramic coated pistons
Urethane coated e brake brackets.

hi had few people ask on shipping price

i have a limited amount

124.00 USD shipped by DHL
99.42 EUROS shipped by FEDEX

i am not trade just made a few set to cover cost of R&D and Materials


these are a direct fit on to the passat syncro trailing arms
they seem to have a more machine flat edge
will post a pic tomorrow

the golf syncro (which came with drums)
most trailing arms i have taken apart to use need a small amount of work to fit as
most of the area these fit to is rusty with age no a big job at all
will post a pic tomorrow
the pictures above are golf syncro arms which had drums so they do fit

[bam20v]

hi what size are they ?

and are they front ?

[GOLF1398]

280mm,these are front disks...fitted back.

[SlantSix]

I got Vr6 syncro, original 239x9mm brakes. Did buy Audi TT quattro 256x20 rearbrakes(calibers, carriers,pads and dics´s).
If i want to upgrade to 280mm, i need those adapters, 280mm Vr6 front disc´s?

hi yes you do audi tt quattro rear carriers and calipers ,pads and early vr6 front disks 280mm x 20mm

5 x100

i have couple of pairs left

thanks

hi all here a few pics to see the golf mk2/rallye vs the mk3 golf/passat arms

the mk2 golf arms all that i have seem to be the 68.4mm rear wheel bearings
as below and need small amount of work to get the adapters to fit nice

edge needs small amount of grinding depending on how rusty the edge is
some i have had fit without work

and with adapter fitted


the arms with the cutouts all seem to be 68.4mm
----------------------------------------------------------------------------------------------------------------

the passat g60/vr6 syncro and mk3 golf vr6/tdi syncro

all have soild bearing carriers (no cutouts) and use the more common 72mm wheel bearing
also have a lot nicer edge to accept the brake adapter


and adapter fitted

[jonjay]

Hi,

Am I correct in assuming this adapter will fit all VAG mk4 chassis? i.e. Seat Leon Tdi or Golf Tdi? Are the adapters still available?

Thanks!

[weejunGL]

well, not to f|_|ck up this thread, but, if i want to go with 256x20mm rear brakes on my scynro, all i need is calipers and carriers (and ofcourse pads and discs) along with a new back brakehose?

currently having the stock 239x10mm rear on my Golf

[jonjay]

weejunGL - I think you are correct.

Tried contacting bam20v but doesnt seem to be on much. Would really like to get this 280mm conversion.

[bam20v]

hi all been real busy im building a 7mtr by 7mtr workshop at back of my house as i have out grown old one

i have sorted this thread so if people post now i will emailed and be able to reply asap

to answer questions etc

these brackets are to use on the syncro family of trailing arms

eg: mk2 golf syncro
mk2 golf rallye
mk3 passat syncro
mk3 golf syncro

as to upgrading a syncro to 256mm discs (rear) i have not looked at this as i just went from drums to 239mm to 280mm rear discs

but i doubt the 256mm carriers would fit ?

i have changed a syncro from drums to 239mm x 10mm rear discs using the std vw rear rallye OEM parts

this lead me to fitting the 280mm discs as 239mm just looked stupid in my wheels compared to the front discs im running .


as to question about will adapter will fit all VAG mk4 chassis? i.e. Seat Leon Tdi or Golf Tdi

i dont understand question do you want to fit 280mm rear discs on say a mk4 golf ?


cheers speak soon

[mafosta]

pardon my ignorance but what difference would it make at the end if because the brake pad only covers part of the surface of the disk

you will have less momentum that needs to be stopped when using larger disc

so it will be noticable

[TBT-Syncro]

you have MORE momentum with a larger disc, but you have more mechanical leverage.

rear brake upgrades are generally a waste of money/time, once you go beyond vented rotors and lightweight calipers. i'm installing a manual bias adjuster on my car, as stock mk4 calipers are giving too much rear bias, and i need to dial it down (rear end coming loose when breaking from 200 km/h is not fun)

hah, there you go i had it the other way around

[mafosta]

This is what I thought. More stopping power at the back will be like pulling the handbrake at 120miles per hour

[rollercoasterracer]

Has anyone found a 4x100 rotor that would work with this setup? My calipers are shot, and I need new pads/rotors anyways, figured I'd upgrade somehow.. but like some other guys said, I'm not looking for major braking in the rear, mainly looking for stuff that will be easier to get parts for later on (I'm in Alaska, and shipping is a lot of $$).

[rollercoasterracer]

And if people are doing this for the rear... what front upgrades are you running, since the rear's will be about the same size and all..

[copdodger]

I have a 280mm x 22 mm vented brake setup on my corrado but now I cant find replacement rotors.
I've been running this setup for years using mkIV calipers, new hub etc. But cant seem to find anyone running a simmilar setup or replacement parts.

[BSABREN]

HI,
I just got 19inch wheels on my 2001 Audi 225hp TT Quattro and the 256x20mm rear rotors look minuscule.
Will these adapters allow me to bolt up 280mm rotors from early VR6's fronts just for looks?
What exact car year and models are the 280mm fronts from?
What backing plates will work?
Are these still available?
Thanks

[rollercoasterracer]

Finally got them on


Used ECS's SS coated brake lines. Wheels were hitting though (16x7 et20)



luckily, was able to get ahold of some 5lug adapters right away, so improvised to get it rolling... waiting for the real spacers currently (had to go out .5" and it was still barely scraping the barrel).

[ws4eva]

I dont like the idea of redrilling discs. Why didnt you use the G60 280mm front 4 stud discs?

[turbowahnstefan]

Hey, the reason not to use G60 discs is that they have another offset-therefore you need another or highly modified adaptor.I'm desperately waiting for updates on your rallye...

[ws4eva]

Oh right. Are you using a 280mm or a 288mm? I did all my mock up with a 280mm 4 stud disc. Then found a pair of 280mm 5 stud.

[turbowahnstefan]

I use 280mm ones-old vr6 and 280mm G60 on two different cars and have made adaptors for both. 288mm 5stud would need quite another adaptor-we tried that, too but didn't find an acceptable solution, yet. We are on it...;-)

[ws4eva]

Oh are you making these aswell?

They defo look like 288mm discs in the pic above or different calipers to mine. My pad is less than 10mm from the inner edge of the disc.



Should have an update on my rallye after the weekend.

[turbowahnstefan]

I bought a set and thought it could be done better and then I thought about 4 lugs and chamber adjustments. Firstly only for my cars, but my cnc men say: one is none-lets make ten-and thats what we did:http://wp.me/pPqN9-1z


I took such a big pic because then you can see the quality of the work...;-)
