I was just wondering if these rotors would fit our cars? Are they good quality? decent price? standard wrx size or larger or unknown?

power slots are ok.....unless you have wrx brakes up front....they won't fit.

Thanks for the reply. Hmmm, for some reason I thought wrx brakes would just replace our rotors, calipers, etc. So, naturally, I thought these could fit without any mods. Where did I go wrong?

Josh, you don't seem excited about the Powerslots. What would you recommend? Factory OEM parts or any specific brand?

I think you misunderstood me, or I misunderstood you.

If you already have the WRX calipers, brackets, etc on your car, these will fit fine with the associated wrx parts. If you have turbo legacy calipers, brackets, etc, you can not just get WRX rotors and fit them with the turbo legacy calipers, brackets, etc.

Make sense? If you get all the WRX stuff, every thing will bolt right up.

I don't have anything against the powerslots. I haven't used them, but have heard of others using them with fine results. I have my reasons, but I typically just buy OEM rotors and have them cryo-treated. I've had the one set on there for several years now, and they've been great.

yeah, WRX rotors are 11.4" which is bigger than turbo legacy. wrx calipers fit wrx rotors, turbo legacy calpiers fit turbo legacy rotors. not interchangeable.
FWIW, I don't know if I would do WRX brakes again. being unable to fit anything smaller than a 16 is an inconvenience for me. 16" snow tires are not cheap. The upside of WRX brakes is that they are readily available for a good price.

Josh,

About the wrx brakes--it's all clear now. What you explained is how I thought it was. Thanks for taking the time to explain it.

This might be a dumb question but if I don't ask it I won't know the answer: Can any rotor be cryo-treated? I saw on eBay some kind of rotors with some kind of coating on it, so I was just wondering.

Josh, do your cryo-treated rotors have grooves in them from contact with the brake pads? Or are they smooth like they were brand new?

206er: What does FWIW mean?

The "Coatings" usually burn off with heavy brake use.

Any rotor can be cryo-treated as far as I know.

I think when it comes time to replace my stock rotors (WRX front brake conversion tomorrow), I'll replace them with StopTech 2-peice rotors or Racing Brake 1 peice rotors, and have them cryo-treated.

Fronts, check. Time to find an upgrade for the rears...

Cryo treatment is a heat treating process that changes the crystal structure of the metal permanently - the entire thing. It's not a coating. My rotors have outlasted untreated ones 8X longer. Anything that can withstand the high temps they bring the material back up to can be treated. I've heard of non-metals being treated with good results. They will groove eventually, though mine are still pretty good. They've worn thinner than most rotors I've seen and evenly, too.

BAC5.2: Your post reminded of something I read somewhere that the StopTech brakes had a different kind of caliper that actually reduced stopping distances. Can anyone verify that?

Where can I go to get info on Racing Brake rotors?

Steve: So when a rotor is cryo-treated, it will eventually still groove, correct? But because the crystal structure of the metal is permanently changed, the eventually-grooved rotor will still have less tendency to warp when compared to non-cryo-treated rotors. Do I have it correct?

I just was reviewing some info at buybrakes.com on the PowerSlot Plus rotors and brake kits. The site says the rotors are 20% larger but still use the stock calipers and that stopping distances are reduced by up to 33%.

Does that make sense? If the same original brake calipers are used, wouldn't the same amount of brake pad material be in contact with the rotor even though the rotor was larger? So, wouldn't that mean the same or about the same stopping distances since the calipers are not upgraded to a larger size or somehow modified to give a better "bite"? Is my reasoning sound or am I missing something(s)?

The Power Slot Plus rotors for a 2002-2003 early production models are 13.4" front and 12.0" rear.

For What Its Worth

Any NEW rotor can be cryo-treated. Once the metal has been seasoned (used on the car) they can't be treated to my knowledge.

My rotors have very little to no grooves on them, and I'm running mintex 1155 pads, which aren't the friendliest pads to rotors. However they've really been quite good on the cryo-treated rotors. I've been really happy.

Cryo-treating is actually a quenching process, but heat treatment is still an accurate term.

The place I use, www.onecryo.com does deep cryo-treatment. It's possible some of the cheaper places don't hold the parts at as low a temp for as long. It's something you might want to check on, just make sure you're dealing with apples and apples.

206er: Thx! FWIW, IKL (I keep learning)

Josh: Thanks, too, for that info. That question of whether only new rotors could be cryo-treated was in the back of my mind but never thought of asking it.

And, I didn't know there was such a thing as deep-cryo-treating--that's really helpful to know.

So, Josh, why do you use the mintex 1155 pads verus the bobcats or axxis pads?

read up on onecryo's site about the deep cryo thing. It may just be a marketing thing, however they may do something different then other cryo places. I don't know.

I run the mintex because the bobcats were not out at the time I purchased pads, and I'm pretty sure the ultimates weren't either. So that left with metal masters, which were "ok" or some of the other "race" type pads I didn't want to run.

If you have money, endless pads are the shit. If performance friction made a carbon metallic pad to fit the wrx brakes, I'd be running those.

Depending on when I need new pads, I might try the bobcats. I've heard good reviews about them, and the correspondence I've had with carbotech has been real good.

Cool, thanks!
