2005 Impreza RS


Hey guys I am new to Nasoic, and trying to figure out what to do with my brakes. I have a 2005 RS with stock at the moment. I've spent a lot of time researching on the forums but haven't been able to find a definite answer.

I would like to do the H6 rears while keeping the stock 277mm front. I have dedicated winter tires on 15" so I can't do a front upgrade.

I know there will be a 10% shift to the back in brake bias, but will this be to great and make the car unstable with keeping the RS front brakes, or will the car feel much nicer?

I know Subaru made a legacy L with 277mm fronts and 290mm rears, but I'm assuming it has different weight bias. (Grabbed that from a 2002 Legacy service manual)

That also clarifies from anyone wondering if the H6 rear will clear 15" rims. If the inside of your 15" has the same clearance as OEM one's they will clear the H6 rears.

i know this thread is ancient but i really need some help.

swapped out drum brakes for 2pot front/1pot rears.
was told they were from 08 2.5i.

bought ebc greens.
fronts fit, rears don't fit.

the rears have a marking on them: AK FA230 EE

anyone know what they mean, what car these came from, what size i should be looking for? thanks!

Default 16 X 6.5" rims with 55 offset clear 4 pots

Not sure if anyone discovered this yet but from a recent drive train swap I discovered that 16 inch by 6.5 inch deep rims will clear 4 pot calipers if they have a 55mm offset or greater. I have a set of winter tires on 06 to 07 impreza 2.5i rims with this offset that just barely clear where my 04 WRX rims with a 53mm offset do not clear.

This is why you can do 4 pots on imprezza but not the WRX because the 6.5 inch rims have 55mm offsets while the 53mm offset rims are 7 inches deep. the WRX rims are 53mm but 6.5 inch which is a no no.

posted some pics so you can see.

Get some 06-07 stock wheels. If you ever go to the snow and want to run a smaller wheel, you want to be careful about the snow buildup turning to ice and filling up that little space between wheel and caliper. Same with the tire and wheel well. Nearly had one wheel on the car froze solid driving in whiteout conditions for hours from the snow build up on the wheel well pushing against my tire.

Tribeca rear caliper is D1124. Currently investigating if you can use the rear caliper + STI rotor do to a R180 swap for cheap.

Good to know that its the same D size as the BRZ so it should have plenty of track pad options

2006 OBXT

Default subaru/FHI 4-pot/2-pot brakes

this thread is extremely helpful but i'm suffering from hardcore information overload..i've only found a hand full of threads that cover the FHI 4-pot/2-pot brakes AND obxts...and somewhere between backing plates and rotor sizes and parking brakes and the kartboy adapters i've gotten real lost..

trying to determine if the kartboy rear brake adapters will work for my 2006 obxt. i understand the fronts will bolt on.. according to this thread, i have the 274x10mm rear rotors (same as the 05-09 legacy, which IS compatible with the kartboy adapters according to the rallysport direct website (www.rallysportdirect.com/Kartboy-KB-016-Big-Brake-Adapters-FHI-2-Pot-Rear-Subaru)) but i'm thinking same rotors ≠ adapter compatibility..

been looking at this legacy intl thread as well:

my summer wheels are enkei 18x8's but i switch to the stock 17x7's in the winter. just got the car a few months ago, lots planned, but needs work on the front brakes very soon so i am in need. i like these brakes for an upgrade and really like the look as well! (and the price..)

anyway, greetings from a new user...not looking for an easy answer and am happy to dig if it means eventually i can write up later for others in my same position! looking for some direction more than anything. many thanks.

Question Break conversion from drums to calipers

Hi Guys,

I'm from the Netherlands and driving a Subaru Forester from the year 2006 for over a halve year now. And i love the car, i always driven a Vauxhall but this is a different dimension.

After this afternoon i almost discovered a new dimension. The break drums didn't stopped me that much to give me a comfortable feeling during an emergency breaking action....

So i'm here to get myself some rotors and calipers and get rid of the drums.

So i searched the internet and found myself a WRX drive train. This is fitted with all the parts i need. To fit it on my Forester, i guess.

But will it fit? To get the WRX breaking pieces directly on my Forester.

It's a complete set with cabling and all stuff

00-04 Legacy/Outback non-brighton
SVX (5x114.3, 190mm parking brake)
Ver5 STI type-RA (5x100, 190mm parking brake)

290x18mm (190mm parking brake)

The Ver3+ type RAs had the r180 rear end which had the 190mm parking brake as stated, but the top link is a 170mm one. The correct one for the Ver3+ type RAs is the bottom link. Minor mistake
