Not sure if this was mentioned ( I didn't see it but I may have missed it )For anyone thta's swapping rear Sti hubs & rotors & planning on keeping they're 2 pots IT WON'T WORK, The rotors are to large & the calipers won't reach the backing plates.
Just thought I'd share some of my experience
Sorry if this has already been addressed

using brembo rotors with subaru 2-pots? I think that not working is pretty obvious.

You can use 2-pots with the sti rear uprights, backing plates, and parking brake, though. Just need a different rotor.

can you run an 04sti hub on a 2 pot setup to retain the original 170mm parking brake and rotors. Older version sti's came with r180's and 2 pots so how did they run this setup. I'm assuming is like an 06-07 2 pot setup with the 04 sti hub?? there has got to be some kind of oem interchangability hence the guys car posted below. we always get old jdm hand me downs here in the states

It should be 2 pots, right?

I have read it a few times. How bout I just say this. What setup do v7 sti wagons have in the rear? Is that clear enough?? I want to run 2 pots in the rear with an r180 so i want to know how to get the axles to work? Do I have to get sti hubs/knucles to use the r180 axles or what. No one can give me an exact answer!!

Here, old thread nobody answer really...

yes, you need sti uprights to use sti hubs, and you need sti hubs to use the sti axles and diff.

The brakes aren't the issue. Since 2-pot rears and brembos use the same backing plate, so either caliper bolts on. and there are rotors to work with either an r180 and 2-pots or an r160 and brembos.

So what exactly do older sti's with 2 pots have, 170mm parking brake or 190mm? See my attached link above and read my qoutes

I understand what brakes mount to what. I want to know what hubs mount to what knuckes or what can be changed between everything that is OEM when using r180 axles. Obviously there are options cuz they have r180 2potsetup and r180 brembo setup. What parking brake does the 2pot r180 setup have from the factory? Haven't found this answer yet. Just trying to find out cuz I want a broader choice in rotors instead of just one custom option of using sti 190mm parking brake knuckles.

I think it would have to be the r180 and 190mm parking brake.

as for your other thread the answer is yes.

There it is again. No solid answer to the question, just a guess. And yes to what?

I have an 04 sti parts car so naturally the brembo's are going to find their way onto my 03 wrx wagon. I know the fronts bolt up, but as I read on I for some reason got confused. From what I've gathered the rear brembo's will bolt up, but I will lose my parking brake. Outside that there aren't any problems that will occur. Please let me know if I'm wrong here.

Also, since i have the 170mm rear parking brake being a wrx, can I swap over just the shoes for the 190mm parking brake on the brembo rotors, or would I need to swap over the entire parking brake assembly? If needed I'll just swap out the whole damn rear knuckle haha

Wow, swear this was all covered (too death) already.
First off, Tribeca is 5x114. Second, STi hub spline count differs from WRX.
Third, DBA & Brembo both make 02-07 rear Brembo retrofit rotors, which utilize STi rotor surface area / 170mm parking brake. Just check fastwrx.com for the dba4000.. That is what I am using on one of GC8 swaps w/ an 08' R160.

What do mean by 2pot R180 & Brembo R180..? They are both 2pot rear calipers. Are you referring to Subaru Cast iron Vs. Brembo? If so, all aspects of the STi w/ Brembo setups are R180 w/ 190mm parkers. As for the iron 2pots (jdm/uk) all have 170mm parkers.

not sure where the tribeca came into this...


I missed that the spline count was different between the two, but being that I have the whole car I may just switch the front and rear knuckles as well as the axles then (hoping the length between sedan/wagon isn't going to cause a problem). I'm trying to do this swap without having to buy anything because I have a full parts car readily available to pull stuff from.

I am doing the front H6 brake upgrade and I have the caliper brackets but I don't know which model/year rotor to get? What year did they start putting the 6 cylinder engines into subaru's besides the svx? Can anyone help, can't get a straight answer from anyone. Thanks, Dan

Likely what you will be looking for a 01-04 Legacy. That was when the EZ30D was in Outbacks. 05-09 had the EZ30R but the brakes were simply the same as the LGT I believe.


As for the SVX.... Yeah nothing dirrect fit works. 4pots bolt but the pads don't make full contact. There is however a Willwood option for SVX's now. You have to know people to get them though.

Default stoptech big brake kit on a 02 wrx

OK!! Here a question,I picked up a 02 WRX wagon which has lots of mods on it.One being Stoptech big brake kit with 2 piece rotors,I believe 328x28 rotors.It should have 5x100 bolt pattern rotors correct? Is there a solid rotor that I could use instead of going to Stoptech and paying $500.for 2 friction plates only no hubs?? The PO had them cut and I think they cut them wrong, lots of pulsating in the peddle,to the point of it being scary!!! Now they are to screwed up to fix.I really don't see the need for 2 piece floating rotors on the street,or want to pay $500 for them.Would a 04 STI rotors work? Maybe brembo has something with the right hub,offset? any Ideas? I thought I read here that STI rotors are 326x30 that's close?What do you think???? Any Ideas What would fit??? Thanks for any help!! MIKE

+1 for this, haven't seen anything definitive. The OP said it might work, but has anyone actually done it? Any clearance issues with the stock 17x7 wheels?

There are a couple of problems here so far that I know.

First - I think 08 STi rears would bolt up - but it's not confirmed. The only issue there is that you must redrill the rotors to 5 x 100 if they do.

Mounting a GD sti rear is going to be tough. The caliper bolts up -but the backing plate is such that the caliper is way far out. And a bracket will be tough as it wants to have 2 bolts in the same spot.

The other issue - Do I make a bracket to fit 04-07 rears on an 08 - or 08 rears on a 04-07?

As far as FHI 2 pots - I can't even go there yet.

I don't think a GD rear sti caliper will bolt to a GR upright. There isn't a backing plate.

It does bolt on - I am pretty sure I have pics - but the caliper is out farther so the pad is half off the rotor.

No backing plate - you are right. I just meant what it bolts to.

couldn't you just use a larger diameter rotor??

Of course you could.

Do you happen to know where to get one that fits?

http://lmgtfy.com/?q=2008+WRX+STi+rear+rotor+dimensions

The 08 sti rears are very likely to bolt right on your car.

They cost a bit more than goldies but at the moment I see no solution even close to being doable at anywhere near the cost difference between the GD and GR rear STi calipers.
