Psydotek 01-13-2005, 01:14 PM Do these come painted black? Do the calipers need rebuilds or dust seal replacements every so often? Are the Hawk HPS pads street pads and/or rotor friendly? Light/Heavy dust levels?
[i might seriously consider these when my tax return arrives...] :)
Paisan 01-13-2005, 01:22 PM Only come in Red unfortunately.
These are not the seals like found in several other calipers, they are double-sealed and don't melt under heat of racing, therefore no rebuilds are needed unless there is a problem.
The HPS pads are great street pads: Low noise, Low Dust, Easy on Rotors, and great stopping power from cold.
Hope this helps. I wanted black also but since RB is a small company they had to go with red to attract both the Tunerz Crowd and for those of us into racing/performance the color isn't a big deal, the real draw of these units is their performance. :)
-mike
Psydotek 01-13-2005, 01:41 PM Very nice. Thanks for the info. :D
Yeah, i wanted black since i don't want any theives to be attracted to the nice expensive calipers i have on my car... But i suppose a little caliper paint could fix that. :)
[oh yeah, you suck since now these have officially been added to my list of things to buy...] :p

bemani 01-13-2005, 02:50 PM How big is the 'bigger rotor'?
infantsam 01-13-2005, 03:38 PM something like 325 x 28 2-piecer is what I heard
omahasubaru 01-13-2005, 03:40 PM Can you show some more detailed pics of the quick release pins and how they fasten on and come out... that is assuming these do offer quick release pad installation like the FHI 4 pots do.
How do the seals handle salt sand for those of use in the snow belt region of North America?
infantsam 01-13-2005, 04:04 PM the pins are just the same as the subie 4 pot - cotter pins on the end
the seals are internal so the piston will be exposed when the pads are worn but the seal keeps the junk out of the piston bore - its similar to Alcon design and is pretty good because boots melt but unsealed pistons can get frozen
omahasubaru 01-13-2005, 04:08 PM same retainer clips as well?
It's hard to tell from the pics, no shots on the back side of the caliper.
infantsam 01-13-2005, 04:15 PM mike may have more pics - but I've changed pads in his car once already - its not the identical parts but they are just as easy to change pads.
Pull the cotter pins - tap the pad pins out and the pads are free to be changed. I did it in no time while watching the football game
Javier 01-13-2005, 04:57 PM something like 325 x 28 2-piecer is what I heard
325mm is a pretty big rotor (12.7"). I doubt that will fit under a stock wheel. The largest kit I've seen for stock wrx wheels is 310.

The larger rotors will not fit under OEM wheels, you will need larger wheels to fit the larger rotors, however you will not need new calipers, just a set of rotors and brackets and you are good to go.

They come in at roughly 5.5lbs each not sure if that's more or less than the willwoods, however we don't consider the willwoods a viable alternative since they don't have the double-boot and need rebuilding every 6-months in winter climates, and don't take standard pads, good luck finding pads in a pinch at Pepboys on the wilwoods after you toast your pads at the track on sunday afternoon in the middle of the mountains of western NY.

Paisan 01-14-2005, 10:40 AM yall also plan on making some 2pot rears? and offering them in gold :)
No plans for Gold as of now, if anything Black. As for rears... The rear does so little braking, compared to the fronts, there may or may not be plans for 2-pot rears. From racing experience the rears are meaningless with outstanding fronts, currently our Impreza will do endos with the RB fronts and OEM Drum rears.
-mike
Arnie 01-14-2005, 01:21 PM Can we assume these are properly balanced with the stock brake system, i.e. doesn't destroy the brake bias, and perhaps, actually improves on it?
Jon-RIWRX 01-14-2005, 01:52 PM These work with the 05 Legacy GT?
- Jon
infantsam 01-14-2005, 02:29 PM They wouldn't work as is - the legacy rotor is half inch bigger and I'm unsure of the offset, thickness and if the locating points on the knuckle are the same
It may be that a 1/4" spacer does the trick.
bemani 01-14-2005, 02:36 PM They come in at roughly 5.5lbs each
5.5lb is with the bracket & pads?
If not, what's the total weight?

-mike
I prefer to increase rear braking some... seems to help brake straighter & more controlled as well as reduce some nose dive and the brakes have more affect in mid corner for rotation. Thus I run a pad with more bite in the rear than the front (just a little) shifts some of the braking back, makes the ABS hold out longer before kicking in and really stops well.
I'd like to see these in black with a 2 pot rear option. Hopefully it won't be too much work to get these in black. Perhaps a GB could get the supplier to make them in black?
Psydotek 01-14-2005, 03:01 PM My plan is to get the Racing Brake 4 piston calipers with pads, keep my current front rotors, and then upgrade the rear rotors with the H6 modification and keep the stock rear calipers. Should be a nice upgrade for the front and rear for just around $1000. :)
infantsam 01-14-2005, 06:54 PM pads - bracket - caliper together is 7 lbs according to my super accurate bathroom scale - (plus/minus a ton)
Arnie 01-14-2005, 07:07 PM Still wondering about the brake balance. Are these properly brake biased a la StopTech? Or do they maintain the same brake bias as with a subaru 4pot 2 pot setup?
BTW, its great having another alternative 4-pot out there to fit under the stock WRX wheels. Esp. since they work with the stock rotor. Good job guys! Let's see if they hold up!

That couldn't be answered that easily.
Brake bias for the vehicle is set according to OEM pads, tires, suspension and weight distribution. Also, the vehicle bias may be set somewhat to the front as that is 'safer' for the average driver. (Rear brakes locking in a turn will surely spin the car?)
However as compared to the FH1 4 pot front (on 294 rotor) the pistons are a bit smaller so that would shift bias rearward slightly assuming all else equal.
I'd expect that this caliper with the H6 rear upgrade would provide a very nice brake setup in terms of balance, heat capacity, cost and maintenance (pad choices)
Arnie 01-16-2005, 04:42 AM Cool, thanks. Just wondering if its something the engineers took into consideration when they put together this caliper. There are more than enough hacks out there with a CNC machine who think this sort of thing is easy to to do and then think a few months of testing are all it takes to make an effective and safe component. Brakes are one thing we don't want to take risks with.
w0rXer 01-16-2005, 12:32 PM It would good to know for sure that these do improve the overall braking balance. Can you get any hard numbers on piston area? A more even distribution of clamping forces is a good thing, but what is the effect on net clamping force?
And I agree, a GB on black calipers would get more people in the game for sure.
Psydotek 01-16-2005, 01:10 PM I'd be down for a GB in black if it ever happens. :)
infantsam 01-16-2005, 03:12 PM I measured the pistons - 38 mm which is about 3 mm less than the FH1
But the FH1's haven't given me even pad/rotor wear - the rotor definitely got tapered and worn more on one side. Anyone else notice this??
(we generally run HP+ on the race car)
Cheveyboy 01-19-2005, 05:29 PM Two questions, first one is what pads do these use exactly? These calipers will work with the same pads from the 4 pot subaru calipers? But cant use the same pins and clips? Question two is, will the upgrade chew threw stock rotors? Are stock rotors realy viable to use with this setup. Or am I defenitly going to need to go to sloted some day? Im primaraly a daily driver, and i could not stand sloted rotors on my last car. But was forced to go with sloted because i would over heat and warp rotors left and right. With no track useage. So its realy a question of how good of a quality are the OE Rotors.
Thanks :)
BTW they look great!
mikaust 01-19-2005, 06:33 PM Will they fit aftermarket 16's such as the ssr's?
I think that they look and sound great, especially the ability to use oem rims, since that's what I use for winter. I think that the calipers should come with a free stencil set, so people can pant the calipers a different color and keep the name.

Its the same pad as the subie 4 pot - They come w/ the pins and clips - The caliper bodies are prolly not the same width so they wouldn't be the right length
The pads used will determine whether or not your rotors get chewed - unless you use a pos rotor.
And as everyone is starting to learn - me too - usually (not always) the rotors just have uneven deposits from the pad. Stoplight to stoplight racing can do that - holding a hot pad against the rotor while not rolling
AdamRX 01-19-2005, 10:28 PM bingo^^
I have a pair of RB slotted street rotors, and for the longest time I thought I warped them only after a month of use. Well, after a couple of months of lots of vibrations, and reading the Stoptech page about the brake pad deposits, I took action. I used Garnett paper and sanded down the rotor/brake pad deposit, and the once "warped" rotors are now gravy.
Cheveyboy 01-20-2005, 10:15 AM Yea, i know you actualy dont warp rotors, its almost imposible to physicly untrue them. Its the depostists that cause cementosis or somthing like that. Friction material embeded i the metal.
I know the pins come with the calipers, but what if they needed to be replaced. Subaru sells replacement clips, pins, and ratle gaurds. What about for these RB Calipers, can you source that stuff. I dont want to by somthing and not be able to find parts for it.
Thanks!

Your rotors will only get chewed up if you us agressive pads such as Hawk HP+ or Blue. If you stick with HPS pads or similar you won't chew up your rotors. As for the pins and clips they are not the same as the OEM ones.

I am not sure if the pins and clips are the same as other calipers, however in the unlikelyhood that they were to break and RB wasn't around, then obtaining pins wouldn't be terribly hard for a machine shop to replicate. I haven't brokent them even in race conditions yet.

If yes, please make me an offer (PM) for the calibers incl shipping to 1230 Vienna Austria.

Farabomb 02-16-2005, 01:01 PM The stock size of the WRX rotor is 294mm so there is no issue using the RB calipers on that rotor.
I don't think a "H6" upgrade in is the future but there is a 2 pot rear caliper that will accept a vented rotor in development.

They have 38 mm pistons - a bit smaller than the JDM 4 pots (41.? i think)
This would move bias rearward a bit - likely desirable for any car w/ upgraded suspension

Farabomb - Are you implying a 2 pot rear caliper is under development from RacingBrake, or are you referring to some other manufacturer ?
I would certainly be interested in a rear 2 pot upgrade to match the RB fronts. Someone mentioned earlier that it doesn't make much difference, but if that's the case, why would Subaru ever have bothered producing their own rear kit for some of their higher spec models ? Seems like a lot of effort to go to just to keep the marketing boys happy.

They are under development by RB to match the fronts. My personal feeling is that the rears don't do nearly as much braking but folks like to have em matching, so we'll give the customers what they want.

If I had to hazzard a guess, I'd say "Yes" have we tested them on '97 GT rims, no we haven't tested em on them. I believe they are 16x6.5 same size as the OEM WRX rims in which case they would fit. I don't know anyone with the 97 legacy GT rims, or I'd offer to test fit em for you.

I run these fronts with my drum brakes on my '96 L racecar. Since the rears do a very small amount of braking, I would upgrade the fronts to these and then put a set of HPS pads on the rear.
