06-07 WRX 4 pot brakes... FIT!

the_paynter · #1 07-06-2009, 08:26 AM

Well I finally took some time yesterday and tried my 4pot brake calipers / pads I had laying around on the SVX.

In short.... they DO fit.

In LONG...

The Caliper bolts on fine. The notch for the rotor needs to be sanded down (width wise) VERY little. (I did it with a piece of 80 grit sand paper) for the rotor to fit width wide. (it fits on without doing this but the rotor will rub on the caliper... you could just do this and drive down the road and it will fix it self but thats a little ghetto)

NOW... The big issue is you NEED to go to a slighly larger rotor (about 1cm bigger in diameter) and there is the proper amount of room on the caliper to allow this bigger rotor. You CAN use ur stock rotor but the pad sticks about 3/4cm over the top of the rotor. If you did use the stock rotors you would have to REMOVE this part of the brake pad as it would hang over as it wears.

If anyone can tell me a slighty larger rotor that fits the SVX hub i will try it out.

Pictures to come when i get home from class

I will also put up the part numbers

How is this possible? I personally tried fitting these, and they weren't even close.

I had them on yesterday. They most definitly fit.

Im refering to the red ones not the BREMBOS... the Brembos definitly DO NOT fit, tried that first

This is very interesting... Those Subaru brakes are reported to be pretty good. I believe they were standard fitment on the late 90's 22B STI GC-chassis Impreza.

Any hope on the corresponding 2-piston rear brake calipers? are they anywhere close to fitting?

I wonder if the STI discs, or perhaps Tribeca discs, both being 5x114.3, would work for the increased diameter... but that is a common hub pattern, there are probably discs from another application that match SVX's dimensions, plus a bit of diameter... just a matter of finding them.

check the DBA catalogue

I've read theories on Legacy Central that the Tribeca rears would fit on our cars, but I've yet to have the time/money to try this out.

i never thought of tribeca discs... they are a little smaller then STI ones and bigger then the SVX discs... have to grab a pair of these and try them out. uploading pictures now

Here ya go. Took it for a ride like this and it worked great but i took them back off until i get a proper size rotor

Wow, the disc looks barely narrow enough to fit through the caliper.

So perhaps as well as a bit more diameter, a mm or two less disc width might be good, too.

Thats what I was saying... it needs to be sanded down. This is PRE sanded, these were taken before any modification has happened. Ill being doing a full install write up with pictures when i install them.

I had to do the same thing when i put 06 2 pots on my old STI in the winter (winter set up)

Well i looked it up and the tribeca rotors are 12.4inchs (aka 315mm) Stock SVX rotors are 300mm i believe so this would give up an extra 1.5cm. This would increase the size of the rotor by 3/4 of a cm all the way around which should close up the gap a little. The only problem is the Tribeca rotors are suppose to be 30mms thick... where the SVX rotors are 26mms and already rub... dammit.

Well heres what I did FIND....

2004 Nissan Maxima (a34 model) has a 320mm rotor that is 26mm thick, its 5x114.3, and the bolt holes are 14mm (SVX is 13mm, i believe this play would be ok but correct me if im wrong)
