Default JDM 95 Sti RA. Brakes? Rotors? Pads?

Hello all,

it looks like my rotors and brake pads are done for.... getting this weird rubbing noise coming to a stop from the rear. The fronts have a lil bit of pad left, but not much and the rotors are pretty much done.

Before I begin, I'm not familiar with brake systems... So I have tons of questions and I'm not 100% sure what mine is... let me know what brake setup is called (I am guessing it's the 4/2 pot?):

Front:


Back:



So I did tons of research trying to find pads and went with EBC brake pads for the 91-95 Legacy 2.2 Turbo.. I think it's the same *correct me if I am wrong* I used this chart: http://www.buybrakes.com/ebc/pad-apps-Subaru.html

I also ordered the goodridge SS lines: http://www.buybrakes.com/goodridge/apps-Subaru.html (1992-2001 model)

Now, I'm looking at rotors... I am not sure which one I need to buy... I don't want to go OEM and was looking at the EBC ones to match the EBC Redstuff pads. According to the 93-96 Impreza manual, which includes the turbo model, the rotors discs are 10.91" dia (front) and 10.47" dia (rear). Following these specs, should I order these?

Front: http://www.buybrakes.com/store/EBC-GD729
Rear: http://www.buybrakes.com/store/EBC-GD728

Help this noob out!

Someone please correct me if i'm wrong but this car should have came with 2 piston front and 1 piston rear. It looks like your fronts were upgraded to the later 4 pots and the rears left as the stock 1's.

Other than that i'm no help. GL

You have the 4 pot / 1 pot (sliding) configuration, which was the normal setup on early STIs (except the TypeR ones which had the 4/2 pot configuration).

That means you should also have vented front and rear discs (294 mm front and 266mm rear).

The front discs should be the same as 2002-2004 WRX and the rear ones should be the same as 1992-1993 Legacy Turbo...

Take a look at this thread:

Order your front pads and rotors for 07 wrx and your rear pads and rotors for 93 turbo legacy. Those are the USDM equivalent.

05+ rotors are different... aren't they? At least according to EBC.

I ordered the front pads for 93 turbo legacy... I guess I'll have to change that order to 04 WRX.

I went with 04 WRX rotors (front) and 93 turbo legacy rotors (rear)

From what I understood, only version 3's and up got the 4 pots in the front and only the RA's got the rear 2 pots.

Alright, I got the pads changed before it got shipped.

So 04 WRX rotor coming in with WRX pads for the front (4pot)
92 Legacy turbo rotor coming in with legacy turbo pads for the rear (1pot)

Of course, they are all EBC parts.

You're going to need 06-07 wrx front pads. 04 wrx front calipers were only 2pot and the pads for those will absolutely not fit.

Does anybody know if when upgrading from 1 pot (sliding) calipers on the rear, to a 2 pot setup, you need to necesarilly replace the rotor?

I know the 1 pot setup uses a 266mm rotor, while the 2 pot setup uses 290mm, but I was wondering if you can you install the 2 pot caliper on the existing 1 pot rotor, and just buy the mounting bracket?

now that I think about it, I should have probably upgraded to the 2pot rear too while I'm at it... oh well haha.

Let me know if you find out the answer to your question.

Weird. Their system is screwed up in that case then.
02-05, 08+ WRX all have 2 pot calipers up front.

Ok got it... now, is there a real improvement in moving from a 1 pot rear caliper into a 2 pot rear caliper?

I'm asking since the braking bias of Imprezas are 70% front / 30% rear, so just wondering if there's a REAL improvement (from a functional standpoint, as clearly from a "exterior look" standpoint it does).

Probably better off getting better pads/rotors?

I see... I'll have to talk to them

EDIT: I think I understand their error. Unfortunately the part was shipped so I would have to return it (which I assume I have to pay for shipping)

for the 2pot calipers (02-05, 08+ WRX): Part #DP31661C
for the 4pot calipers (JDM STi, 06-07 WRX): Part #DP31200C

Gahhh

EDIT #2: I was able to smooth talk to them and waive the restocking fee (20%). Unfortunately I'm off to training for a month so my car will be in the garage for a while and even more after I get back. Oh well, I guess I can work on other things.

So Version 2 STI (both RA and non RA types) comes with 4 pot fronts and 1 pot rears?

I am going to be going through the same thing this week and want to ensure I purchase the correct parts for my 95 V2 STi.

So what do I get for front rotors, front brake pads, rear rotors, rear brake pads?

Well, if it comes with 4 pots front and 1 pot rear, you will need:

2004 WRX front discs
1993 Legacy Turbo rear discs
2006 WRX front pads
1993 Legacy Turbo rear pads

Version 2's do not come with 4 or 2 pots. They just get the 2/1 setup.
There are quite a few threads about brakes on WSC and jdmvip if you're on there. I can't remember off the top of my head the ones you'll need. Best bet is to bring them in and start comparing them to a 91-96 legacy.

not really as the V3 type R got 4/1 and then the V4 got 4/2 and having driven both cannot find any difference in braking ability (standard pads/discs).

I'm surprised that Buybrakes doesn't stock the Bluestuff NDX which have been getting plenty of good reviews in the UK

I own a 1995 STi and recently did my brakes.

You have turbo legacy (1991 to 1994) brakes all around (the 1995 STi and STi Type RA ARE THE SAME). You MUST make sure you get the ventilated rear discs, the solids are incorrect.

To reiterate, you need turbo legacy front pads, turbo legacy front rotors, turbo legacy rear pads, and turbo legacy rear rotors. Some of the info you've been given in this thread is beyond terrible
