Direct bolt-on calipers
 
I've searched thru a bunch of these brake threads, and just so I haven't missed anything, there are NO upgraded calipers that will directly bolt onto the SVX, yes? I read one that said WRX calipers have the same bolt holes, but the SVX rotors are too thin and you'd have to get thicker rotors.

So again, there are currently NO calipers that are a direct, bolt-on replacement for the stock SVX calipers that won't require changes to anything else?

correct there needs an adapter to bolt up any other caliper

There is a project over on SVXNATION And HISE-TECH to bring over the 4-pot calipers, designed for the JDM SVXs.

4pot front/ 2pot rear, plus larger rotors, designed for the OEM 16" wheels.

As far as I know the JDM SVX didn't use any other calipers, if so we could just put those on the usdm svx they didn't change any brake mount locations on any of the svx, it wouldn't make financial sense to do so. for such a limited number of cars, However that being said there is a plan underway for "cheap" 4 pot/2 pot to be made to fit

Check with Jamie Price over on SVXNATION. This is the whole idea. The JDM 4 pots do fit. He can explain all the technical details to you. Send him a message.

The first sets of calipers are en-route from Japan. For those of you inquiring about the brake upgrade kits Unfortunately they are being shipped PAL which can take up to 14 weeks to get to Philly.

Re: Direct bolt-on calipers
 
That sounds all well and good, but right off the bat I wouldn't be interested in that, because the JDM calipers would have to come from Japan, and I'm sure they won't be cheap. What I'd be interested in is being able to take calipers off a WRX or something similar, and with minimal effort, bolt them right up to a stock SVX brake system. No bigger rotors, no changing hubs, etc. That, combined with s/s brake lines, should be a "Stage 1" brake upgrade. Simple, not very expensive, and something that won't require special tools or a lot of time.

Ryan Clark, not sure if he is on the forum here, is working on an adapter that will bolt up with cheap 4 pots that can be found here.

I don't know if your famaliar with some of the wrx community happenings, but caddilac has a very cheap brembo that bolts up to wrx's with a simple adapter that is now easy to get, I believe with a adapter those cheap brembos should work with the svx

Well now... :p
Ryan Clark is an active svxnation moderator fellow eastern pa resident and personal friend of mine who is helping us with the 4 pot upgrades. Nothing usdm bolts up period... The JDM Legacy and forester Subaru 4 pots do match up and will fit under the stock wheel as well as the JDM GD 4Pot brembos. But- the brembos require 18" wheels. We can get JDM Legacy 4 Pots shipped to us for half the price of used Brembo calipers. Either caliper can be used with the stock rotors but will have pad overhang. The rear calipers require the correct backing plate swap in order to to bolt up. Let me know if you have any further questions in a format that is at least younger than my kids :p (ie Instagram twitter Facebook tumblr google plus pintrest etc etc you name it svxnation is on it) https://m.facebook.com/groups/1668220880085258

It would be nice if there were some kind adapters available that would allow other calipers to be a direct bolt on, but as far as I know, there's nothing. I had a 2005 HD Sportster 1200R, and replaced the stock 2-pot front calipers with Wilwood 4-pots, and they were a direct bolt-on. I know I'm comparing apples and oranges here, but for the sake of a simple aluminum adapter, is what's preventing us SVX owners from upgrading our calipers.

One of the Australian members Darin, I think E on this forum has had an adapter for the 6 pot brembos for years, The problem is costs, Machine shop cost and the liability that they have to take on if it fails.

yes, with those 6 pot brembos, you need 18's the 4 pots may be able to fit stock 16's.

I personally think 18s' are the best size though lol

I'd be happy with 4-pots, since I just got some 17s, lol...

But on this car, 6-pots are probably overkill in stock trim. I have a 2004 Saturn VUE with the Honda 3.5 24V V6 with a 5-speed auto, and that vehicle is MUCH more responsive to drive than my SVX. I think the Honda 3.5 is rated at 250hp, so it has more hp than the SVX, but the VUE just gets up and goes without too much effort. On the SVX, it has a much more leisurely acceleration pace, unless you mash the gas pedal. That's fine by me, it's not really a sports car, more of a sports tourer, and for that it does a great job!

I used to have a Harley Sportster 1200R, and upgraded from the stock 2-pot calipers to Wilwood 4-pots, and that was plenty of brake for that bike. I would imagine going with a 4-pot / 2-pot setup would achieve pretty much the same results on my SVX, all with fitting under my current 17" wheels.

Try driving a manual transmission SVX; completely different animal. With the 4EAT engine revs are soaked up by the torque converter first, but with the 6-speed the SVX is more jumpy than my Legacy in Sport Sharp drive mode.

Yeah, given a choice in this car, I'd much rather have a manual than the automatic. But since they didn't come with manuals in the States, it is what it is. I'm okay with that, I have the VUE, two Triumph motorcycles, numerous firearms, one daughter doing grad school in Ireland, and another one ready to graduate from the University of Hawaii, so it's not like I don't have other things to spend my limited funds on, lol...

Re: Direct bolt-on calipers
 
I agree 4/2 is good and will do great on the svx, 6 is just for looks/overkill, I would do it if money would let me, but not required.

And ya with a manual, especially 6 speed this svx wakes up you will never look at the car the same. If I can make it to the 25th meet I would let people drive to see for themselves.
I have the engine, I just need to drop it in, I should swap over my waterpump/timing belt as mine are new and I don't know anything about these but water pump gasket isn't in my current budget lmao.

Yea, I am here. The caddy brembos require a bracket and a 355mm rotor. Project is on hold while I get my svx ready for car season.

Hope you get to trying the Cad calipers soon because I've been thinking of the same project but didn't want to experiment since it's my daily driver and can't be down for too long.

HarvesterUT 01-31-2018 12:26 PM

Re: Direct bolt-on calipers
 
I've been doing a lot research and question asking as well. Here is what I've found out so far.

I'll start with REAR brakes because it's the most straightforward.

Parts you need:
2006-2007 WRX STi rear backing plate
2006-2007 WRX Sti rear rotors
2006-2017 WRX STi rear calipers

From my research it seems the calipers are functionally the same, it's the mounting point that was modified in 2008 - it went from a backing plate design to an ear-on-knuckle design. This moved the caliper offset by approximately 4mm which is why you want 2006-2007 rotors. To swap backing plates, you need to remove the rear wheel bearings. This would be a good time to replace wheel bearings. :)

As for the FRONT brakes, it appears that Subaru made a custom knuckle with caliper mounting tabs that are located slightly further away from the hub than any other Subaru ever made. What this means is that any other subaru caliper you want to use will be ever so slightly too far away to fit precisely over the oem size 2006-2017 rotors. I am not sure how much the difference is, but I have read anywhere from 1 cm to 15mm. Not verified by me. What this means is that you could modify the metal tabs on the knuckle to move the bolt holes closer to the hub. I do not know how feasible this would be with clearance of other knuckle components, however, I think this *might* work. Alternatively, you can source a custom made bracket that adapts to the more current "Brembo GT calipers" made in 4 and 6 piston styles. These brackets allow these calipers to work with 355xx x 32mm rotors (Mustang GT500 size). The downside here is that you'll likely pay a bit more money for the Brembo GT style caliper, and you'll need to locate a pair of said brackets. If you're a stickler for looks like I am, you'll also need to custom paint/powdercoat all 4 calipers to match.

Laguna_Blue 02-01-2018 01:16 AM

Re: Direct bolt-on calipers
 
Pardon my ignorance on the subject.

Could we not just switch hubs with a Tribeca or MY05+ STI so that Brake parts are more universal?

I know that the splines are different on the half shafts(an hub), but wouldn't taking the hub side of the half shaft apart and switch to the half shaft with the appropriate shaft spline for the hub.

Its a little more work at the beginning but may be cheaper and pay off in the end.

gwynethh 02-01-2018 04:57 AM

Re: Direct bolt-on calipers
 
The following is a cut and paste from the SVX Nation Face Book thread on the upgrade of the front calipers to 4 pot.

"So after seeing a bit of interest in doing the 06/07 wrx and jdm 4/2 pot caliper swaps, we have decided to put a feeler up for anyone interested in our customs cnc'd front caliper spacers. These are designed to widen the front 4 pot calipers to accommodate a Tribeca front rotor on our SVX's. Shout out to Ryan Clark for doing all of the mock up work so we had the measurements correct to make these.
Prices will be as follows, and will be based on the number of people interested.
1-9@$90/set
10-19@$80/set
20+@$70/set
One set includes 4 total spacers for 2 front 4 pot calipers.
I will leave this post up for one week with a running list of interested parties. At the end of the week, I will take payments for interested parties and submit the order. I'm being told it should be about a 2 week turn around from the time the order is submitted to the time of completion due to a heavy volume of work at the machine shop.

*note* you will need further components to complete this swap not included with these spacers
-Tribeca front rotors [any year]
[06/07 wrx calipers]
-z32 caliper pins
https://www.z1motorsports.com/…/fron...mm-and-…
-an extra set of caliper o-rings, same part number as whats in the caliper rebuild kits. Here is a link to a kit for just the extra set of o-rings
https://www.z1motorsports.com/…/z32-...ng-kit-…
I will keep a running list on this post, so please pm me of you have any questions or interest in getting on the list so its easier for me to keep track. "

In our mind not too bad a tested and verified option. The only known issue is wheel clearance with the oem wheels. May need a pair of 5mm wheel spacers to clear the oem wheels at 10-20$. Oh, info in [ ] are my adds to clarify the info. Not our investigation, not our info or parts order.


Very short time to get in on this as the spacer order will be submitted Feb. 2 2018!!!

This would not be possible without fabrication work. It has been looked at and abandoned by at least one member. The lower balljoint is completely different on the GD chassis cars so the knuckle will not just bolt on. The CV shaft splines are actually the same, so that is not the issue. But getting the knuckle bolted on is the problem.

Search around and you might be able to find the thread about it.

Jvan 02-09-2018 08:09 PM

Re: Direct bolt-on calipers
 
So HarversterUT, Have you done this swap? Does this swap use the 2 pot calipers and what is the thickness of the rotors? I'm considering during the upgrade for the front rotors/calipers being offered by SVXNation which uses Tribeca rotors and WRX 4 pots. Wondering what the combined effect would be?

shotgunslade 07-05-2018 09:03 AM

Re: Direct bolt-on calipers
 
I'm pursuing the WRX 4-pot/Tribeca rotor big brake system that has been developed at SVXNation. This system requires using custom 6mm milled spacers that give the calipers a wider opening because the Tribeca rotors are 30mm thick rather than 24mm for the WRX rotors. These I sourced from Josh Bettencourt, an SVXNation admin. Bought 2007 WRX 4-pot calipers on eBay. Also purchased Nissan 300ZX pad retaining pins, which also are longer and an additional set of O-rings to seal the spacers. Will source either Stoptech slotted cryo-treated or Frozen rotors slotted rotors. Some issues involving length of cap screws that hold the two halves of the caliper together. Spacers reduce thread bite depth of the cap screws down to 10mm from 16mm for stock calipers. Have sourced 80mm shaft hex bolts to replace 75mm shaft OEM bolts. This big brake mod is alleged to be a direct bolt-on. Others have finished the installation and verify that. Waiting for my rotors before I do the installation. This installation should give additional braking capacity because the WRX rotors have a slightly larger diameter than SVX rotors (316mm vs 301mm), are slightly thicker (30mm vs. 28mm) and because the WRX calipers are 4-pot rather than 2-pot as are the OEM SVX rotors. Will report back when I finish the installation.

Jvan 07-05-2018 02:16 PM

Re: Direct bolt-on calipers
 
I am also doing this upgrade and am waiting for my rotors which I sourced from DBA, although they don't list rotors for the Tribeca (same size rotors listed under 2015 WRX). I'm deciding between painting vs powder coating of calipers. Where did you source the longer hex bolts so I can have them when I'm read to complete the install?

shotgunslade 07-05-2018 02:58 PM

Re: Direct bolt-on calipers
 
Belmetric.com

8 x BH10X1.25X80YLW - Hex Bolt Yellow Zinc 10.9 (BH10X1.25X80YLW) = $20.64
------------------------------------------------------
Sub-Total: $20.64
Flat Rate (Orders under 15oz ship via USPS First Class. Orders over 15oz ship USPS Priority.): $7.99
Total: $28.63

Note that these bolts are grade 10.9 steel, not 12.9, the highest strength. I don't know what is the steel grade for the OEM bolts (cap screws). I couldn't find any M10 x 1.25 pitch 80mm shaft grade 12.9 zinc-plated hex bolts. I did not want to use black oxide coated bolts for corrosion reasons. Grade 10.9 steel has an approximately 17% lower yield strength than grade 12.9. But the 80mm shaft gives 50% more thread bite depth than the 75mm OEM bolts, bringing it almost back to the 16mm of bite that the stock configuration has. No one seems to know the torque setting for tightening the OEM bolts, which could give a clue as to their steel grade. With grade 10.9, zinc coated 10mm shaft diameter screw, you should use 45.2 lbs-ft unless the vendor says otherwise.

Jvan - What flavor DBA rotors are you getting? Looked at the T3 - 4000 series, but they are pretty dear. T3 -5000 series is out of sight.

Jvan 07-05-2018 03:20 PM

Re: Direct bolt-on calipers
 
I purchased the 4000 series from Hawk performance; they had a 50% sale in addition to their normal discount so the cost of a set of slotted/drilled 4000 series gold was $240 per pair w/frees shipping. I think that was a great deal but it ended last week.

shotgunslade 07-05-2018 04:13 PM

Re: Direct bolt-on calipers
 
That is a great deal. I got Stoptech slotted, cryo-treated for $259 for the pair. Had to look all over for them. Out of stock everywhere. Finally got them from J C Whitney.

shotgunslade 07-18-2018 07:46 AM

Re: Direct bolt-on calipers
 
I became aware of a new rear brake upgrade opportunity through my discussions with Josh Bettencourt at SVX Nation. It involves incorporating the 06-07 WRX rear 2-pot calipers and the 05 Sti rotor. While the rotor isn't any larger in diameter than the OEM SVX rotor, it is 18mm in diameter and is vented vs. the 9.8mm diameter unvented SVX rotor. The 05 Sti rotor has a 190 mm parking brake, as does the SVX, vs the 170mm for the 06-07 WRX, but is otherwise identical to the WRX rotor. So, while not greatly increasing braking force, it likely will increase fade resistance, due to greater ability to shed heat. It utilizes a conversion bracket and spacer package that is supposed to mate the 06-07 caliper to the 00-03 RS backing plate. Unfortunately, the spacers don't quite line up the caliper with rotor as installed on the SVX, so you have to add some washers or custom spacers and play with it a bit to get the correct rotor/caliper alignment. Josh has installed his retrofit but isn't completely satisfied with the alignment and wants to do some further measurements before finalizing a recommendation. I've ordered the bracket, which hasn't yet arrived. Will keep everyone posted. Here is the link

Re: Direct bolt-on calipers
 
Instead of adapter brackets, you can swap the usdm 05-07 STi rear backing plates on and the 2 piston FHI or 2 piston Brembo rear calipers will bolt right up using the 05-07 STi rotor. The backing plates are available new from Subaru.

Re: Direct bolt-on calipers
 
Are the rear backing plates bolt-on?

Tireiron 07-19-2018 01:48 PM

Re: Direct bolt-on calipers
 
Yes, that is what is on my car. 05-07 STi rear backing plates, rotors, and Brembo 2 piston calipers. Fits as OEM. Also the 05-07 STi rear wheel bearings and all of the parking brake parts are the same.

shotgunslade 07-19-2018 01:51 PM

Re: Direct bolt-on calipers
 
so, if I didn't want to spring for the Brembo's, the standard Sti 2-pots would also fit?

By the way, are the non-Brembo calipers for the 05-07 STi, the same as the 06-07 WRX?

Yes, the FHI 2 pots fit to the same 05-07 STi backing plate, however the STi never came with them. USDM 06-07 WRX came with them (and 170mm parking brake with 5x100 hubs) and a bunch of older JDM models.
