Not on my car, well not on the brakes anyway.

Well I guarentee 100% that the Subaru brakes don't fit the Astina. They may fit an Mx-6 or Probe but the Astina caliper uses a different mounting method.

Are they the Legacy 2 piston Rod
Thats a shame :(

There are apparently only two types of twin pot calipers on Subies and I've tried both. Next month I'll try and get some 626/Mx-6 brackets and see if they will mount to the Astina then I may be able add the Subaru calipers but of course I'll probably need to use the smaller 626/Mx-6 rotors.
The Astina caliper uses two pins that extend into the bracket while the Subaru has one pin mounted in the bracket and the caliper slides on that. The other end of the caliper moves on a barrel that is bolted to the bracket.

Well I picked up the GE 626 brake calipers today and they came with almost new Lucas brake pads WOO HOO Winner.
I have to change the pins and bolts between the brackets but so far so good, everything appears to align. By the time I've built one caliper it will be the weekend so I can check the fit.

So the theory goes - Use a GE 626/MX6 caliper bracket to mount a Subaru XXX Twin put caliper (using a combo of Sube and Mazda slides/bolts) and then bolt that to the Astina?

Have I got it right?

V6 Calipers don't have two pistons do they?

ROB-80E 21-09-2007 01:59 PM

No just one big one in a floating point caliper.

RedLineResident 21-09-2007 02:05 PM

So really the V6 brakes wouldn't be a great deal more powerful, just better due to larger brake pads.

I thought that was the case. Now V6's are about 70kg heavier (i think i read somewhere) therefore the advantage of the bigger pads is leveld out when you add the extra weight.

Cosmo Dude 21-09-2007 02:24 PM

Yes and no.
The V6 rotors are larger then GE 626 rotors and the GE is bigger, heavier and more powerful so the V6 brakes ar much better than the 4 cyl ones. My worry is that the 626/Subie combo may not fit over the larger rotors.
If they don't then I'll jump onto and try to recover some cash.
With some luck I should be able to test fit them on the weekend and maybe have them fitted by the months end.

The 626 brakes are also the same as GE Mx-6 and some Ford Probes.

RedLineResident 21-09-2007 02:29 PM

So are the astina rotors bigger than the 626 / mx6 rotors.

thats what i gathered from that post. I could be way way off ofcorse.

Cosmo Dude 21-09-2007 02:33 PM

Yep, not by much about 16mm extra diamater on the Astina

RedLineResident 21-09-2007 02:36 PM

That makes no sense, the 626's are a bigger, heavier car and their V6 engines are hell torqueier and pick up speed well. It doesn't make a great deal of sense to put smaller brakes on them.

Dad's got a 96 626, hes gonna spew when I tell him that my tiny astina has bigger rotors than his.

Awesom, that made my day.

ROB-80E 21-09-2007 04:48 PM

The V6 brake upgrage on my BG astina combined with DBA4000 rotors and Lucas pads made a HELL of a difference... I'm still working on getting the ABS side of things working, but i'm getting there.

I'd like to know if there is a difference going from the V6 brakes for the V6 brakes with a subie caliper...but at this stage, I haven't seen the need to upgrade any further.

Cosmo Dude 21-09-2007 08:36 PM

I have just found that the 626 in question is a GD not a GE :o Oh well back to the wreckers next week.
The only thing on the thread was that it is posted in the 1st gen section. On the bright side the GD rotors are only 10mm smaller than the BA V6 rotors.
If I do need GD rotors they should be much cheaper than the BA V6 ones, Greg?

Cosmo Dude 21-09-2007 09:08 PM

Just found that Eunos 800 N/A rotors are the same diameter as BA V6 and 6mm thicker. The centerline of the rotor is possibly too far inboard.
The HD 929 is 274mm across and 24mm thick with a similar center.
The BA V6 is 274mm across and 22mm thick. 21-09-2007 10:17 PM

question - how would BG8Z GTR front hubs/rotors/calipers fit a BG or BA Astina?
i'm assuming it is a straight swap, but others will know more.


ROB-80E 23-09-2007 08:20 PM

No they won't go...only upgradeable on the BG GTX. The 4wd hubs are designed to work with a 4wd steering rack (yes they are different). Even on the GTX you still need the struts to go with.

The GTR brakes are essentially the same as the BA V6. 23-09-2007 09:17 PM

the reason i ask is that you can get D2 / G4 / K-Sport 330mm rotors and 8 pot calipers for $2300 off the shelf for a GTR, (or $2600 for 356mm,) much bigger than the little toys currently being played with.

bugger the GTR hubs cannot be used then.

ryan 23-09-2007 09:49 PM

What about 626 brakes from same era? Or they just V6 brakes?
