sti brembos on gtr

[Indy-R]

Yes, please dont be lazy to come back here and submit your results/finding, Also try to make some pics!
Also, did anyone checked/played around with newer FX35??? Their front calipers looks huge!

I will forsure. Might even make a bunch! Seems like everybody needs adapters..

I belive you need to use 04-07 sti rears , funny I was installing coilovers on a buddy's 09 sti yesterday and I noticed how different the rear calipers are then the previous generation

Yea kinda weird how they decided to do that.. Oh well. I just want the fronts mounted, not too worried about the rears. Stock gtr rears aren't really thatt much smaller honestly.. Could just use some new stainless lines!

From what I heard Subaru actually made there hub around the r33/r34 brembo rear caliper so it's literally the same

Similar to the STI brembo and identical in rotor size, since you will need the evo's 5x114.s and hub clearance, the EVO 8/9 brembo upgrade.
Stock BMC. Pedal initially had a little more travel that I liked. I put new pads on and it helped. Just did the Rear brembos w/ss lines this week and it feels very very good.





The above picture shows the work required to get it to fit. It was not as easy as putting R32 brakes on an S14 and this bracket was designed for the S-chassis. Interchangeable my ass.
Here is where it hits.


rim1 - Advan SA3R with a +45 offset - eww
rim2 - R34 GTR +30
rim3 - Te37 +22

You'd expect the TEs to clear with room to spare right,it's one of the best rims by design and weight out there. However it does not. It's more about spoke design. It's unfortunate though at Advan doesn't make a fully forged wheel. Every advan style I've used has cleared in the highest offset even.


SA3r clears


R34 clears


the almighty TE37




This is a custom setup though. The car the brakes came off, the evo9 with the same wheels would clear. But because of the bracket and spindle design we're using it does not.

Great post! I wish I seen that diagram before I did mine lol. I didn't need to trim the bottom of my knuckle probably my adapter design (skull works I think) I used the Evo 9 caliper as well and I've heard the Evo and sti uses the same caliper but the Evo uses a 32mm rotor vs the sti witch uses a 30 mm. The difference being the sti pads are a but thicker to compensate, somthing to think about when getting pads for sti calipers being that its using the 32mm rotor. I plan on the rear in the future as well did you feel a pedal difference when the rears are on?

[GTR203]

Also just noticed what it says About the 5mm spacer not sure if my brackets are v1 or v2 but I did not use any spacer and it centered perfect using the Evo 9 rotors. Brand new pads and no drag.

[zac3ne2nr]

Yes the bracket design allows for a little more give. I was using the TougeFactory set. I prefered to cut the non essential parts of the knuckle instead of compromising the bracket.
Yes the pedal feel is much better balanced now. I want to get that Stagea260RS BMC though to send some more stopping to the back.
The rears:


Yeah I used the same brackets on my S14 and did not have a centering issue. Weird.

I think zac3ne2nr using this EVO calipers on GTSt were you did that on GTR??? That is why maybe on S14 it didn't needed the spacer.
I REALLY hate the idea of spacing rotor from the hub, it just doesn't seems right!!!

Do you guys both using this TougeFactory brackets?

Also, have anyone did an STI calipers swap? Proved with pictures? I read here that STI and EVO are looking to be the same but still would like to make sure for me and everybody else that it is indeed true!
(Edit: Yes they are the same! I found a thread with both calipers being tested on S13/S14 knuckle - CLICK )


And just to recap you guys both using EVO Calipers/Rotors???? What generation EVO?

[GTR203]

I am using Evo 9 caliper / rotor with skull works adapter on a gtr with no spacer and its perfectly center.

[zac3ne2nr]

evo9 caliper, oe brembo rotor, tougefactory bracket on GTST- 5mm spacer reqd between rotor and knuckle.

So there is a lot more talk about the front then rear so what are you guys using for a brake upgrade in the rear

Im pretty sure its been stated before that GTR rears are not that much smaller than anyone of the cars we recently talking about! (STI or EVO8/9)
For a show or look you want to use 04-07 STI rear calipers as they suppose to be direct bolt on! No grinding or bracket required! And i belive you have to use EVO8/9 rotors??? For the correct offset? Also R34 N1 rotor might also work!? (Please correct me if im wrong)
