Brembos... Finally doing the test

[shotgunslade]

In my post, I made mention of the fact that the SVX caliper mounts sit further out than the WRX. Hence, where the STi 4 pots on a WRX have a 295mm disc, the same calipers on an SVX require about 320mm.

If you go to the Brembo's, (which on an STi require a 320mm disc), by the same logic, you'll be needing something like about 345mm disc.

That's one big disc.

What I'm wondering though is: Can I mount 2005 STI Brembo calipers under 17" wheels. The above post seems to suggest not.

Sti wheels are 17" factory

17" rims will fit the rotor. What you have to worry about is will the offset of your rim clear the rotors, or will the spoaks catch on it.

I'm currently running 48mm offset, so would greater or less offset be required to provide adequate clearance? Also, still don't understand Dynomatt's post below. He seems to be saying that puting the 2005 Brembo's on an SVX would require a 345mm rotor, 20mm larger that the OEM STI rotor

No, he weas guessing... He is using Nissan Calipers... Trust me, if the brembos don't fit, I will buy them from you, Make sure you get all the mounting hardware as well

You're good to go Dan.

Stock '05 STi wheels are 17x8" with a +48 offset - exactly the same specs as your Rota Boosts!

Still chasing Sti calipers, but the bid is getting up there. Wondering about these on from an eBay shop:

This sell is for a Subaru 4 pot caliper upgrade kit. The kit includes left and right calipers, one set of Hawk HPS brake pads and all neccessary mounting pins and springs!

These calipers come painted black!

It there is one weakness to the WRX, it is its brakes, and the more power that you make, the more obvious this becomes. Subaru has finally addressed this issue on the 2006 WRX by putting on Subaru’s 4-Pot brake calipers, and now you can retro-fit these calipers to your WRX and dramatically improve your braking capacity.

The Subaru 4-Pot calipers were first used on the 2000 – 2001 JDM STI, and are what many Subaru Rally Teams are currently using in Open, and Group-N classes.

These calipers are a direct bolt on, and use the same front rotors as the 2002 – 2005 WRX.

Because these are 4-Pot calipers, these calipers may not clear your wheels.

The kit included

- 1 pair of calipers

- 1 set of Hawk HPS Front Pads

- All necessary mounting pins and spring

Please check out our store and email any questions.

Those aren't s good as the brembos, and are the same as the ones found on my '06 WRX (just not painted red).

[shotgunslade]

So what size rotor would they require, if bolted on an SVX? I assume I might have to switch to '06 WRX rotors because of hat size and offset issues and bolt spacing.

[NeedForSpeed]

Are you sure? The calipers pictured are iron, I believe, with raised letters. The 06 calipers are aluminum?, without raised letters. Can you confirm?

Not sure what size rotor they would require. But those are similar to the Nissan 300ZX calipers - TomsSVX may have test fitted some and would be able to give you a better answer.

To the best of my knowledge, the calipers pictured are aluminum (just painted black). The Nissan 300ZX calipers were cast iron/steel IIRC... My '06 calipers have the same raised section with the SUBARU letters painted on.

[TomsSVX]

the mounting bolts will allow for them to fit but the rotors will not. Since the STi uses a different hub, the rotors are different than wrx rotors. In short, we do not think the suby 4 pots will fit. Only the Brembos are known to fit easily. The Nissan 300zx calipers are aluminum and the suby 4 pots are cats iron. The brembos are aluminum as well as far as I know

Gotcha. I wasn't sure which was which...

[jman050]

has anyone tested the STi brembos yet with success??

Edit: NVM i read toms post

[Bwana]

Speaking of which...anyone around Chicago thinking of doing this might want to jump on these.
