I was wondering if I bought brembo rotors to fit on an 02 WRX if it would work with brembo brake calipers from an EVO 8. I'm wondering if the calipers were the same size as an STi's and all I need was rotors and brackets.
Ok, my comments on this. You will absolutely need to have it machined. That idiot talking about the angle grinder, well, my only comment on that is "the brakes are there to bring your car to a stop, if you want to just hack modify that system, that is your business." You'll have to have the spindles machined too... This all depends on how much work you want to do. This guy claims 2 hours. I'm going to call :bs: on that, or say that the guy has access to tools and such that you probably don't have access to. I don't know the cost of the machine work, but if saving a few bucks is worth it to you, then go for it. You will need to remove your spindles and give the spindles and the calipers to your machinist and have him machine the mounting points so that the caliper sits centerlined to the rotors you intend to use. The guy in that RS25 link used Spec B rotors. So you'll need to figure out where in relation to the spindle mount points the centerline of the rotor is, and then have them machine the spindle and the caliper to put it where it is supposed to be. Keep in mind you cannot go back to stock brakes later on with this route unless you replace the spindles.
Thanks, I found this DIY from the same site, it should work on a 02 WRX, right? http://www.rs25.com/forums/f105/t101318-evo-brembo-install-yes-suby.html He has the same Rims as me so that answers my question about clearance issues. I'm going to do this later down the road but I think the red brembo brakes both look great and perform well. The good thing about it is it's not that expensive to do. It costs about $500 to get EVO brembos and rotors which is way great IMO.
I hate seeing this many people take chances with THE most imporant system on a car. Whatever you do, do not drive behind me.
meh, I was watching that thread from the first time it was posted. the modification isn't anything too severe. the better option, is as mentioned in the end of the original thread (not the DIY), and put a small (~2mm) wheel spacer BEHIND the rotor. this will give the clearance without modifying the caliper. then just need to enlarge the holes a bit. I've been thinking quite a bit about it. my next subaru build very easily might have these....or 300ZX hardware.
If you could somehow find 2mm material, and cut it fairly precisely. Another thing to keep in mind is the rotor is hub-centric, along witha lot of wheels, so you could run into issues there. Or just be patient for some gold Brembos to come along at the right price?
What do you plan on doing with your car?? Because you will be more than fine with a good set of rotors/pads/lines/fluid. If you are looking for a more balanced system, do the h6 rear upgrade. The other thing I would do is start checking the master cylinder sizes. You can put 2000 piston calipers on your car and run 20" rotors, but if the master cylinder can't put the proper pressure to the calipers, it will be a waste of time and money. I am guessing that the wrx and evo master cylinders are not the same size, and if the evo master is larger, you will lose braking pressure at the rotors. Russ
Kinda what I was thinking. I ran into this kind of problem when I was building old hotrods, and it is very un-nerving the first time you take out your 600hp muscle car and HOPE the brakes work as good as you think. And to tell you the truth, we have calculated wrong and it is pretty damn scary. everything looked good until that first big run when you really got INTO the brakes and realized that it just wasn't good enough.

Hmm, I guess I'll just pass up on getting EVO calipers. I need to work more and buy some proper STI calipers.
The stockers will do more than a fine job. Pads/lines/fluid will make a night and day difference, and then you can throw in some new rotors (cryo treated) and you will only have to change fluid and pads every so often. The rotors will out live the car. Plus, with that upgrade path, you will save TONS of money, and good parts are all available locally. Russ
