why not just turn the rotors that you have on there now? Are they below spec?
I have the Rotora Cryo treated slotted rotors. did I notice any difference when i installed them? NO.

Nosenuggets can better answer this question for you.

I can't see why your worried about slotted rotors. You should have the brembo brakes, no? That shit is good enough IMHO. Huge difference in them over standard wrx brake system. Not sure about the 04s. But it should have the EBD also...electronic brake distribution system. Which balances out the braking power to make you stop better.

All slotted rotors do on a street car is make more break dust.

they also eat your pads quicker

they do help w/ glazing, your only going to see glazing at very (very) high temps- read track days

i have power slots on my car for over 35,000 miles and have had no probs with them at all, by buying slotted rotors they wont warp as bad nor as fast they keep the temp down, so there is an advantage to buying them cause they will last longer than stock ones.

the reason your rotors are lasting is likely the metallurgy is good, it's not the slotting- slotted rotors of the same composition will actually last less (as some material is removed for the slots) long

many of the higher end rotors are slotted (some the only way the come)- they are good rotors because of the way they are made, not because they are slotted

see above for the advantages of slotting

Yeah, my brembos make enough brake dust as is. I don't need to amplify it anymore. In a weeks time my rims are covered. Plus, it doesn't help that i occasionally drive fast and then have to stop fast...heh But, still...to each his own i guess.

--------------insert automated brake response #29-----------------

Unless you track your car your wasting your money on any brake modifications. let me say that again to be perfectly clear, unless you drive your car on circuit race tracks you are wasting your money on ANY, yes, ANY brake modifications short of decent pads. brakes do not stop your car, your tires do. all the brakes do is absorb the heat generated by slowing 3200lbs down.

buying slotted rotors to reduce glazing on your pads is ridiculous. if your pads require bedding then just bed them. it takes 10 minutes.

I will mention that SS lines do help with brake feel. Won't necessarily help you brake any faster, however.

I agree with vew on that one. But I also agree with nuggets too.

To me the pedal was so mushy it did not inspire confidence even in day to day driving, the SS lines helped a lot which made me feel better, not necesarrily helped performance.

Id go for some regular DBA blanks or something like that.

Easier on pads, dust, and wear usually. Unless you want to be like all the SuPeR CoOl StReEt RaCeR guys in Reno.

by mushy im assuming you mean the peddle had a lot of travel. thats not fixed by SS lines, the bleed required after the ss line install is what fixed that. the SS lines will give the peddle a slightly firmer feel, but by themselves wont reduce peddle travel.

Most people associate "break feel" with how hard they have to push on the petal to get the desired break response. harder lines increase the breaking done per bit of force you mash (at least under partial breaking) hence they improve "feel".
