I think there may be something on scoobymods about wrx rotors but i am not sure about sti rotors. think it should be the same. Put the car on jack. Remove the bolts behind the calipers that bolt it to the hub. Then you thread a screw into one of the holes around the center of the rotor untill it pops the rotor off. It is pretty easy. Hardest part is breaking the bolts loose to get the caliper off. Just know that whatever screw you use to break to rotor free from the axel will probably be busted at the end, so have 4 screws ready.

No link but easy to explain:

1.raise the car using floor jack and jack stands
2.take of front wheels
3.look at the inside side of the caliper and yuoll see 4 bolts, 2 of them have a little rubber sleeve that they screw into, dont touch those. Take the other two off.
4. once you take those off you can remove the caliper (dont let it hang on the brake line though)
5. pull off the rotor

Same for the rear.

EDIT: wait Sti brembos dotn have the rubber sleeves, forgot its 4 pot for a min.

That basically sums up how to remove calipers in one piece. I use a short bungee cord to hold the calipers to the springs, works beautifully.

....no....

It's held on by the lug nuts...and the rust that's built up after awhile. After you remove the caliper it can come off, now depending on when the last time those rotors came off, it might be a huge PITA

The rust might REALLY have a hold on them. If you're having a tough time, you could use a ball-peen and give the rotor several raps to help break the rust loose, or you can use a bolt to screw into those two empty slots to help push it off the surface. I THINK it's a 8mm or 10mm standard pitch bolt...but don't take my word for it.

living in souther california you shouldnt have to much trouble with rust. I usually pull mine off with no problems but if its giving me trouble i get a mallet and hit the rotor a couple of time top bottom then side side.

Well normally we don't...but...rust can develop quite easily after a long drive. Drive around a lot, park the car for a little bit, come back, and you'll be guaranteed to find some oxidation on the rotors. And remember that rain we had half a year ago? That stuff definitely built up some rust.

Don't forget that brakes create a lot of HEAT, that always speeds up chemical reaction.

Definitely use the bolt-hole removal method. It's absolutely the easiest way. I don't remember the size either, though.

I think the one that holds the wiper arm on, can be used in a pinch....

It uses an 8mm 1.25 bolt. Can find these at any decent hardware store, Home Depot, etc... I would also buy a few extra. I also have used Pb Blaster on the threads of the bolt to help it thread into the rusted rotor, makes things alot easier.

I think the jack bolt method is a waste of time. PB around the hub - wait 1 minute then tap the rotor - that has never failed me and I live in the NE
