STI front brakes on BRZ (confirm)

[endrswrd]

So to put STi brembos on the brz you need a set of brembos, 04 sti rotors, rear adapters.

Then swap the bleeder orientation on the fronts, and throw them all on?

Is the adapter being used the same one as the adapters for older wrxs to fit brembos without swapping hubs?

I am not interested in getting into the rest of the debate, just want to try and cost estimate this as I might do it when I do wheels / tires / suspension come spring.

Sorry to bump an old thread, but I'm interested to hear from anyone who did the brake swap and installed the calipers on the "wrong" sides so the leading piston becomes trailing.

How is your pad wear long term? Any other unforseen side effects?

I did the swap on my car a few days ago. I did it with the correct orientation, but was unable to swap the bleeders, and the line orientation being outside the posts bothers me, so I'm tempted to swap sides.

Cheers!

Wait what? The part in bold is confusing me. Do you mean the brake line on the back of the caliper is not lined up properly? From what I remember CSG Mike and other sayings, it is ideal for the blelders to be swapped. How come you could not do it? The brake caliper has 4 holes that concern us right now: two on "top", top on "bottom." If you mounted your brakes in the correct orientation, you should have two bleeders in your "bottom" two holes (because you have not swapped the bleeders).

P.S. Your build is sick

I think he's talking about the brake line not being blocked by a solid part on the caliper? I know the stock calipers kind of block/contain the line, but I haven't seen the brembos up close.

EDIT

Guess not. I will find a correct photo for this

Thanks for the reply's people.

I'm using calipers from an MY08-12 STi and on mine the banjo bolts screw in on the bottom hole rather than the top (when the calipers are mounted with the correct piston orientation meaning the bleeders are at the bottom), so the posts do not secure the line.

Anyway back to my original question, can anyone provide feedback on the pad wear when the brakes are swapped side for side so the piston orientation is incorrect.

Yes that's exactly what I mean

That only applies when the caliper is mounted to the rear of the axle like all other Subaru's (except BRZ of course). However, when you mount these calipers in front of the axle, and if you want to keep the proper piston orientation, two things will happen:

a) the bleeders become upside down, and you'll need to swap them over.
b) the mounting tabs for the banjo bolt is now at the bottom, and can no longer secure the brake line.

Odd that photo was taken from that STI Brembo swap DIY lol

Nah that was just some random photo of an sti. You can see the front drive axle there

My bad haha

Just installed 05 STI callipers on to my BRZ. I decided against going through the hassle of swapping bleeders after reading Element Tunings real world experience without doing it. It's not that I'm incompetent or lazy, I just preferred not to due it since they are 9 year old calipers and more than likely would cause more headaches than anything else. I'll post up impressions on how it goes so that we get some more real world data on it.

When I went out and bedded the pads tonight I noticed immediately that there is a lot more bite in the brake pedal now. I'm not sure what to look for in degraded performance, but I was pleasantly surprised when I hit the pedal aggressively from 100km/h.

If uneven pad wear or premature pad wear are the only detriment to this orientation then I honestly could care less.

Also, are there any concerns in mounting the brake line outside of the posts if you do swap the bleeders?

Are you sure your bleeders are swapped? Your brake line looks like it's in the top hole.

My thoughts exactly. I've been using mine the 'wrong way' round for a couple of months now and for daily driving I don't feel any side effects. Pad wear appears even so far. Perhaps longer term, or if you track the car, then you might see uneven wear. But then again if you track this car you should be using the Sprint kits instead of the Brembo's anyway.
