Kbrate listed the dimensions of the disk. These are for the Legacy BE/BH with vented rear disks. The caliper is almost identical to ours but wider to accomidate the thicker disk. Ditto for the caliper bracket.

As for the number for the disk changing to AE031... its possible. Subaru does this all the time.

cardin - you are the man. Now how about some prices on these components, you can post them in yen, we can convert. We need the calipers, caliper brackets, pads and rotors(oem rotors are optional-DBA makes an excellent version I highly recommend.) Theoretically, our stock backing plate should work once the dust shield is removed or bent. However, to be safe, see if you can get the backing plate part number and prices as well.

kbrate - I see you have been following my work . That backing plate is a non-OEM white elephant of unknown origins. The guy who posts them says he used to make them himself by drilling extra holes in a stock plate(I don't believe this for a NY sec-the material to drill wouldn't be there if it had not been stamped that way when it was made.) Further, he says they are no longer available. In theory, it would be an excellent item(no doubt the reason it was devised,) because it would leave you the option of installing either the single pot or 2pot rear calipers on the same backing plate. I think he bogarted the pic from someone else at some point in the past, got drunk, forgot where he got it, and then came up with a fantastical story to explain all these events. Oh wait that was me .

The stock H-6 rear rotors are already 290 mm in diameter so I think it will not be required to change the backing plate.

The prices I have are:

322.95$cdn for each caliper (new)
185.59$cdn for the pad kit
73.38$cdn for each caliper bracket
193.72$cdn for each disk

Its not cheap but it is rather easy since you just unbolt the old and slap on the new.

I should be able to get everthing listed above with a lead time of about 2-3 weeks. Shipping has not been factored into those prices.

I case anyone is wondering, I got these prices from Subaru Canada.

Default hmmmm

The rotors are gonna be ~$257 plus shipping. I definitely would want to go with the DBA slotted version. Nino qouted me $85 each for the DBA slotted rear rotors.

cardin in reference to the pad kit, that is one kit for both rears right?

322.95$ cdn for each caliper (new) x2 = 645.90$ cdn
185.59$cdn for the pad kit x1 = 185.95$ cdn
73.38$cdn for each caliper bracket X2 = 146.76$ cdn
193.72$cdn for each disk n/a

Total = 978.61$ cdn = $628.32 + shipping

BTW guys this is the alternative I had been working on, I wasn't gonna say anything until I was sure it would work and what parts were necessary and I was gonna post it here first. I am glad that the Legacy forum has tracked down what would be an excellent rear option for any of the Subies. These part numbers cut right to the chase. One of the annoying lingering questions had been, will the current US rear caliper fit the vented rotor. Ciper brought this up earlier. I feel cardin has helped clear all this up. The absolute verification would be to find a seperate JDM part number for the caliper being used with the non-vented rear rotor.

This option comes in significantly less than the 2pot rear kit and utilizes the same rotor. If any of you have read my posts elsewhere, I think you know I believe the rotor is the most important integral part of the braking system, by a long shot. IMO, in a hierarchy, this is how I would rate the four mass produced Subaru rear rotors:

266x10mm

266x18mm the vented aspect does not outweigh the larger swept area and mechanical advantage of the next choice

290x10mm least expensive 2nd best choice

290x18mm the Grail as far as stock rear rotors go, the only one better is the 316x20mm Brembo STi rear rotor($$$$$$)

The reason I have spent so much time trying to find this alternative was to get this rear rotor. I even went so far as writing and calling Perrin Subaru trying to get them to develop their rear kit using this rotor. I believe even a stock single pot caliper using this rotor is gonna outperform the Perrin 2pot rear kit using the solid rotor.

The only loose cannon on the horizon with reference to the rear brake options for a Subaru is the Baer rear kit. They developed an excellent rear kit for the Focus.

Subysouth: Well, here is what you wanted.

There is a separate JDM part number for calipers and brackets for non vented rear rotors. The vented ones are only on the B4 RSK and the GT-B. All non turbo Legacys get solid rear disks. Hope this helps all of you.

And yes, the pad kit is for both rears (lh and rh).

Default Well

It's official, a have a set of BH GT-B rear takeoffs secured now(in the hands of an overseas friend-not here yet.) It includes calipers, caliper brackets, backing plates and pads. The owner upgraded to the 2pot rears, so he kept the rotors. I will be sourcing my rotors from DBA. The correct DBA number for the 290x18mm(170mm parking brake) rotor is 653. I'm getting the slotted version, so its 653sl and 653sr.

I dont know how long its gonna take to get them here, as they are coming from overseas. I also don't know how much the total cost is going to be. I unfortunately was ordered not to reveal the source of this rear setup at this time (this was done essentially as a favor.) I imagine I annoyed at least a couple of people trying to track it down.

I have been after this setup for a while, I only originally guessed it existed. Thread:http://forums.nasioc.com/forums/show...+turbo+caliper

That idea didnt pan out

Crazy Ken, I don't have an idea of the repeatability of what I have done, however cardin's supplied part numbers will yield the same result. The pads may well be the same as those used on the WRX and Legacy solid rears, I can verify this once my set arrives. I do think cardin is correct about not needing the backing plates for the install. I got them because the owner had to swap them anyway(these plates don't work with the 2pots.) So, in theory, you may only need to source the calipers and caliper brackets from the overseas dealer.

I have borne this headache because I am an admitted rotor fiend. You now have several options to choose from. IMO, at this time (Baer rear kit availablity - unknown - but probably $1000 for the rears when done,) I would only consider the "H6" upgrade, this upgrade, or the vaunted Subaru 2pot rears ($1300.) These are my cost vs rotor quality recommendations.

Subysouth: Keep us posted as to how that install goes and what your final cost was to get the parts and so we can see if it is cheaper for me to get them or to just import them from Japan.

Do you have a guinea pig yet? I am anxious to see how it goes.

I was reading through your post and noticed the info about different calipers on different years and models. Just wanted to clarify the Forester position.

I have a MY98 Forester S manufactured 05/97. My calipers are the newer style and did not need to be changed when I did the "H6" upgrade.

Here is my post with pic, parts and prices:
http://forums.nasioc.com/forums/show...hreadid=237363

Is those prices you listed for the parts after tax?

I just thought the prices looked high, but I guess that's cause I bought mine before SOC increased the parts prices.

Are you clear on what we are talking about here? You have the JDM B4/GT-B brakes with the vented rear rotor on your forester?
The threads you linked in the Brakes forum were all about the H6 upgrade. If you do have the JDM set up you get props in my thread. If not the the Legacy forum keeps the props

Unfortunately, we do have clarification due to one of the threads Tselway linked. Brian(North Ursalia) verified the "older" calipers are not compatible with the "newer" calipers and brackets. So to get to the "H6" upgrade, all of us with pre-2000 Legacys would have to replace the caliper, caliper brackets, rotors and pads to get the "H6" rotor on the rears.

This makes this JDM path even more attractive, cause why not pay a little more to ultimately get a lot better rotor.

Yes and No

Yes, all 2000+ Legacys with rear discs have the 290x10mm rotor.

and

No, Austin does not have the upgrade that is the thrust of this thread, he has the "H6" upgrade. And even tho this thread is titled that way, if you READ it you will see we have resolved another upgrade which uses the 290x18mm vented rotor found in Subaru 2pot rear kits and in this case, on the rear of JDM 2000+ B4s and GT-Bs.

See above on this page Crazy Ken. I listed all the part numbers and the prices that I would get them for. I am not sure where else to look to get them cheap. Most vendors concentrate on the Impreza and do not cater too much to the Legacy.

ok so i reread this thread...allow me to summerize

266x10 standard on most every thing since 1990 w/5 lugs
266x18 legacy turbo vented
290x10 2000+ legacy
290x10 2 pot vented

98-99+ (depends on model) rear calipers will bolt in to brackets for the 290x10 rear disks

so here is where my confusion starts you have 290x18 rotors and calipers compatable with them (2 pots) but it is my understanding that you needed the hubs that are compatilbe with the r180 diff to get the 2 pot rears to fit .. the whole bolt spacing issues

edit: wondering if B4s and GTBs have r180 rear difs...

Default nope

The 190mm rear parking brakes/rotors only came on 2001+ WRX-STis.

It came in the form of a 290x18mm(190) on the 2001 STi and 316x20mm(190) on the 2001-2 STis equipped with Brembo brakes. There are some other models but generally speaking they are rare.

AFAIK, the 190mm parking brake has never been installed on any Subaru other than the WRX-STi. They wanted the larger handbrake for rallying purposes. The only reason I mentioned it was for thoroughness.

All Legacys, Foresters, std Imprezas, and OBs since 1990 that have rear discs have come equipped with 170mm parking/hand brake.


Quote:
290x10 2 pot vented
I assuming this is a typo, It is the 290x18mm(170) DBA#653, that I am buying which will work with my existing hand brake internals and backing plate(other than the dust shield part.) The 2pots did come equipped on the 2001STi as a 290x18mm(190) DBA#656.

BTW, the small handbrake is 170mm(or some places list it as 160-I don't know why but they are the same size,) and the larger STi hand brake is 190mm(and is also listed as 180, again I dont know why but they are the same)

To try and clear one more thing up:

Quote:

I think I cleared up the R180(190mm hand brake issue) but with reference to the bolt spacing on the backing plates.

AFAIK, all the single pot rear caliper since 1990 have used a 5.75 inch mounting bolt spacing. This is the reason I can bolt the single pots off the 2001 GT-B directly to the backing plate on my 1997 car. Of course, I have to either bend or remove the dust shield at the perimeter to accomodate the larger rotor.

For both the Subaru STi and the Brembo rear 2pot kits the bolt spacing is 4.5 inches.

So it seems with single pots, all versions are pretty much bolt up. If you want to go with a 2pot caliper kit then you have to change the backing plate. For my purposes I am trying to get the rotor used with the 2pots but squeeze it with a single pot caliper. Cheaper and probably 98% as effective. The rotor is the key.

Jaxx, if I may add some thing to Subysouth's very thorough comments, the rear brake calipers on the RSK and GT-B are single piston only. Legacys do not come with 2 pot rear caliper.

So there is no 290 x 10 2 pot vented. It would be a 290 x 18
1 pot vented or 290 x 10 1 pot solid. Hope that we helped clear this up for you.

BTW- From the info that I have, the GT-B and RSK have the R160 differential.
