    STI brakes on WRX

    Hello!

    Serious question... ummm... if I wanted to have the stopping power of the STI's all I have to do is swap out my stock WRX brakes for the STI ones right? Or is there more to that?

    Thanks!

    You will need 2004 rotors since your hub pattern is different.

    Why exactly would you want STi stopping power with stock WRX power? That's not a condescension, I'm seriously wondering, because on a cheap day it's close to a $1000 mod.

    To answer your question, though. Yes, essentially, once you swap rotors and pistons, you'd have STi brakes.
    I have an STi with an intake and no tune, I never change my oil, and my wheel spacerz are mad tyte.

    I'm going to disagree with you. The WRX is overpowered, underbraked, and sprung too softly stock. While I think Brembo brakes are overkill, braking should absolutely be addressed before power.

    Yeah I agree with that, he was asking about STi brakes specifically, though. My brake rotors and lines were one of the first things I swapped on my WRX when I had it.

    Thank you everyone!

    Yea I should have worded the question better, my bad! I meant to ask if the "easiest" and "cheapest" way to improve the handling of my WRX would be getting the STI's brake set up since I feel that the WRX pulls hard but needs to be able to slow down better, like Zax said, a tad too much power for what the stock setup can do to slow down safely.

    Thank you also both for the links and also the tips. A dumb question, but would this potentially allow a dealership to deny a warranty claim if I use 2004 parts for this? Just wanna be on the safe side with this.

    Thank you all again!

    If you have brake issues, and want them to fix your brakes, a different brake setup on the car would absolutely allow them to do this. HOWEVER, if you just got SS brake lines, a nice set of pads (Project Mu is AWESOME), and some nice rotors (DBA 4000?) then you'd be in the clear and have much more precise stopping power.

    I love you. Like no homo. But thank you!

    So I'll probably go along that route since that's under $1500 and will allow me to stop and slow down much better and more safely, which is a must!

    One more question I have is though... ummm... so I'm not sure if I know how to do this little project myself... would it be a bad idea to have my local dealership (that does all of the regular service to my car and where we picked it up from) do the installation or no?

    Thank you btw!

    Honestly, it's pretty straight forward. Go to a car meet, make some friends, offer to buy beers if someone will help you out. It's not a big project, and garages charge heftily for brake work, for whatever reason.

    ok that's fine... I have some friends that can do it but I hate always asking for help since they were always pitching in here and there with my old e36 last year...

    What will happen when I take it in for service in the future though? Will they give me crap for it or play around with me for it?

    It's just replacement parts. Wear/tear stuff. I don't know of any dealer that will try to say anything to you for brakes.

    Well, we of course have WTF Tuning here on the site, and oakos, I'll suggest them first, since they pay to advertise here, but I'm always a huge fan of importimageracing. Usually if you email them, I think it's Sales@Importimageracing they'll give you a bit of a discount.
