does anyone notice any drastic improvement in 4 pot brakes. also does anyone have the rear 2 pot brakes. any info would be great.

Of course.

Expect a 7-12' improvement in braking from 60-0.

To run rear 2-pots, you need STi hubs, backing plates and axles, to run which you need a R180 rear end.

- Alex

cool thanks

I have the front 4pots and 2pot rears on my RS. I think the setup is great. But just a warning about the rears that it is pretty expensive to get those on. Quite a bit of dismantling of the rear is required. But definitely the front 4pots are worth it. The 2 pots are not needed as much.

good info. thanks

If you go to buy a set get then look on yahoo japan right now cause somebody is selling a set of Brembo 4 piston fronts and 2 piston rears for about $500. The usual 4 pistons run about $300 there as well.

Its a worth while upgrade.

Just be prepared for the insane amounts of brake dust you WILL get from the pads that come with the 4pots. If your anal like me you will have to wash your front wheels frequently. But the feel and shorter stopping distances are worth it, trust me.

Hey I hate to disagree with the teacher on the first day of class but.......

The 2pots rear calipers are bolted to a backing plate which uses 4.5" bolt spacing vs 5.75" bolt spacing with the single pot calipers. So you need to replace the backing plate. Alex is sorta right that up until very recently this setup was only available on an OEM application with the R180 rear assembly. However Subaru does now make an OEM application with the R160 rear assembly. The JDM model is called the NB-R Impreza WRX, it is also the UK and Euro WRX. So sourcing the parts(backing plates specifically) will let you install the 2pots on your USDM Subaru without messing with the rear assembly. Also for several years MRT has been making a backing plate to use the 2pots on the R160 rear assembly, it is quite a bit more expensive than the OEM unit.

Since this is my first post, Alex, congrats bro, I'm glad you didnt stay down.

Yeah, I know because I have them on my car :D

I was thinking about the same thing.
4pots or not?

I decided to upgrade my rotors and pads instead.
I think it's more effective than running 4 pots with stock rotors and pads.
Pretty happy with how it ended up. (RG slitted rotors + AP Lockheed ZC pads)
If I had more funding, of course I'd love to do 4 pots (or GDB brembo) with performance rotors/pads.

The latest "cross-eyed" JDM WRX are all 2pots rears too.
I don't really care about the backing plate though.

I'm not super concerned with all out braking. At least not enough to justify the 2 piston rears. I'll stick with the stock rear calipers, SS brake lines, slotted rotors.

can you PM me the link :)

The 4-pots are a great upgrade for GC8 because you get a larger front rotor. In addition, the pad is larger, so heat is spread over a larger area. These calipers are not light, but are virtually indestructable. They will help with brake fade problems and fluid boiling problems on the track. They're fairly cheap, use common TT 300ZX pads and can be bought at a Suby dealer with the subie mastercard bucks (how I got mine). In clubs that allow upgrade WITHIN a manufacturer's parts bin for street stock class (like COM in new england), it's a nice upgrade with the big subie moniker on it to prevent others from protesting the car.

Well if you want the 2pots you gotta have the backing plate, cause thats what the 2pots bolt to. The front 4pots bolt directly to the front knuckles.

The Brembos are only up to about $250 total for the front 4 pistons and the 2 piston rears. The last one is just a link in case somebody only wanted the STI fronts.

hmm. how hard are they to install. i am sure i can do it, but i dont want to have to sit for 2 hours trying to bleed the entire system myself.

Bleeding is NOT a one person job without special tools (pressure bleeder)

However, anyone will do. I used my girlfriend's 12 year old little brother (she's 30 yet has a 12 year old brother...surprise!) He was more than happy to press and release the brake pedal for me.

As far as swapping the calipers...EASY. After removing the wheel, it's 4 bolts and the brake line. And install is only 2 of those bolts (and the brake line) ... that's it.

Hey N/A thanks for the links but I seriously doubt these are gonna sell for anywhere near 28k yen. The seller has them for sale in his shop for 218k yen. The lowest I've seen these sell for is over 100k yen. We'll have to keep watching them, its an auction and they dont close for 4 days. And of course this does no include rotors or rear backing plates, parking brake internals, etc.

k.

I'm a bit different on this one...I am not a big fan of the upgrade. The main reason is that bang for the buck its not all that terrific......a good set of pads (Hawk HPS), some braided lines (Goodridge), and the car totally changes charater.

Now, if you find the 4 pots used for a good price, all the better, but given their asking price of around $600 per set, not at all worth it IMHO.....

What kit would you reccomnend? The Stoptech's are how much?

The Brembos won't stay that cheap. Obviously but they also usually don't make it to the $1000 mark either. Hell the red 22B STI calipers usually only get up to 35,000Yen for the fronts. The thing with yahoo is that it will go through a month or so where there isn't crap posted for sale and then there will be times when there are 400 things posted. If somebody has some patience they will find what they are looking for.

You man yahoo auctions? :confused:

i like 'em :D
plus i have braided lines , porterfield pads and dba rotors :)

plus i can run 15" and 16" rims with them on :)

Another thing to throw into the mix - 4pots for Subaru is the same as 4pots for 300ZX, except the Nissan ones are aluminum, vs cast iron for Subaru... and I read before someone was trying to get the aluminum setup to work on our cars?

I have STi 4 piston brakes, and I love them. I noticed way less fade on enduring drives. (AKA Mountain roads/track)

I also have FHI 4 pot front brakes and they make a remarkable difference, but i also upgraded rotors and brake pads as well. The net effect is the car is literally thrown forward with the braking power of this setup compared to my old RS setup. The previous statement about the weight of the cast iron 4 pot calipers is almost irrelevant because the stock 2 pot sliding calipers weigh almost as much. They were much heavier than i expected, so in reality when you swap them out, you're not changing the upsprung weight in the front wheels by very much.

Ed

Even the Nissan 4 piston brakes are heavy. I just shipped somebody the calipers alone cost me just under $20 in shipping. It would be nice if they came in aluminum but since they don't why bother going over it.

i think i will have to go with z1's ideas. i am into saving money on that part of my car so i dont need to waste it right now.

Does anyone have Brembos thats not an STI? I only saw them on the those cars. I like the gold though... ;)

These dont close for 15 hours, they're scatched, the current bid is 105k yen and the minmum acceptable price has not been met. Just as an example.

Do you have a link to a set of 22b 4pots that have SOLD for 35k yen. The lowest I have seen the red 4pots go for was ~48k. Just been my experience.

Certainly I am sure unusual things have happened but your post seems to make it seem like that there is a ton of parts available on Yahoo dirt cheap and in reality thats a bit of a stretch. You usually can buy brake parts cheaper here after you factor in the shipping. Obviously if its a JDM only part you got to go there for them, but if the parts are available here its usually a wash due to shipping.

If you mean "same" as in uses the same pads that is true but the casting is entirely different. The mounting ears on the Nissan caliper are closer together. The Nissan calipers came in both cast iron and aluminum too.

Ed is almost correct, the 4pots are actually slightly LIGHTER than the stock WRX 2pots. So when you upgrade your unsprung weight goes on a slight diet.

Actually I have recently been lead to believe(from good sources) the oem 22b 4pot front calipers were made of aluminum(not the red-painted cast iron "22b" calipers readily available now.) I am working on verifying this. I have a current quote of ~$1200 USD for this alleged aluminum 4pot kit including rotors. Waiting for pics to verify. To further mix things up they supposedly use a thicker rotor than the 24mm on the regular cast iron 4pots.

Go figure

Kobayashi, I'd post a link to what has already sold but I would need the exact auction ID#'s as well as in order to see the final result you would all have to get an account in order to log in to see it.

Things aren't constantly popping up on there but there are cheap parts to be found. Hell I bought a fully built 1993 GTI-R on there for $2K US.

I am sure there are some great deals to be had. I could go through each one of the above and explain why they are that low. Its either timeliness or condition. For instance brand new naked 4pots can be bought for $475 USD loaded for $580. You are in Japan so shipping will not be that bad for you, but for us shipping (domestic and then international) makes it all but a wash on US market available parts. Used parts have no intrinsic value they could be 90% of original or 10% depending on condition. So I guess what I'm saying is show me a set of NEW black STi 4pots closing such that I can get them to my door for $300 and I will be impressed.

Are you offering a service of shipping these parts to the US?

k.

N/A, would you be willing to help me on getting some of these deals on Yahoo japan?

I'm starting to think these subaru 4-pots would be the way to go.

ok I can't read any of that.
what do I need to do so I can read it?

ok found a translator but all of the brake parts i saw say no overseas shipping

Subaru 4-pots (F) with SS lines (F & R) make an excellent bolt-on, cost effective upgrade. No need to change rotors, and they come with pads and parts. (Although I had to purchase the spring clips separately: my local Nissan store had them in stock.)

Happy Motoring

My question was has anyone replaced their stock brakes (front & rear) with Brembos, on a stock WRX not an STI since they are already on there!

I know some people have put on the gold Brembo calipers. The only problem that I have been told about putting on those specific calipers is that only a few wheels will clear them since they are soo huge. I believe that Alex will be putting on the 2piston rear Brembo calipers on his WRX in the future sometime.

A guy here is using the 2 pot rears (not the gold ones) with everything stock minus the dust shield (removed)! The only diference is using the correct rear rotor which he did. Now he has 2 pot rears with parking brake. I'll see if I can get the part number!

Also, look for the post from Areg which he and Mike Shields (The Guru) have done a modification to the rear rotors of the gold ones to fit in stock place!

Running to get a set of those rotors!

Hey Prodrive Boy, you're annoying me. I would like to know the guy who has been able to bolt up a set of Subaru 2pot calipers(which have 4.5" bolt spacing) to a stock USDM backing plate(which has 5.75" bolt spacing.) Won't, can't, didn't happen. You are correct in a way tho, that up until recently the 2pots were only offered with a rotor with a 190mm internal parking brake incompatible with USDM cars. However that has recently be changed.

The rotor you are talking about is a 290x18(170)mm rotor. Subaru PN: 26700AE030. Found on BE/H GT-Bs and B-4s, and GDA Impreza NB-R, et al. You also need the backing plates(on a side note, these backing plates are incompatible with the ABS pickups on the rear of BE/H Legacys) from the NB-R to make this setup work on GC, GDA, BC/F, BD/G, etc. as well.

k.

Fine, I'm annoying!

But I tell it as it is and soon will have part numbers to proove it so SUCK IT!

Thanks forr all the rest of the info though!

Hey PD Boy I thought youd be pleased you annoyed me I was jus pulling your chain. He cant use the stock backing plate with the 2pots tho. Not unless he has manufactured some sort of amazing adapter as yet unseen. Definitely nothing oem.

Merry Xmas to all....

k.

edit: and if you need PNs just ask.

I bought the Subaru rear 2pot kit for my RS and everything bolted right up. The kit included the backing plates for the calipers, rotors, pads, and pins, etc. But I know that Mike has been selling the gold brembos and have done custom modifications for those that have it so that it will work on the USDM cars.

Now just for clarity. When you say "bolted right up" you mean after you had the hub pressed out of the knuckle, the new backingplate bolted to the knuckle and the hub pressed back in correct? Meaning when I say, "bolts right up," I usually do not include in that a trip to the machine shop. Just a rhetorical question for those who may not know what is involved in this install.
