Rotors Questions im looking to upgrade my brake rotors, i was really looking into getting cross drilled and slotted rotors, but i am unsure what name to get, relatively cheap.
so who sells a good rotor that will fit with stock calipers?

I recommend these:

Why? a number of reasons.....
1. Drilled rotors cost swept area. That's metal that is no longer there to contact the brake pads, which is how the car stops.
2. Drilled rotors can absorb less heat, add that to the fact you started banging holes into a structure made to not have them (all drilled rotors for this car are standard rotors with holes CNC'ed into them later) and weakening them... and you get something more prone to warping and with less stopping power.
3. Drilled rotors don't do anything to help the performance of the brakes.
4. The ATE rotors are coated with a baked on, powdercoat like finish to keep them from rusting.
5. The slotting means minimal loss of swept area and minimal loss of of structural integrity. In fact ATE doesn't even make a full blank rotor.
6. The ATE slots are shallow. Deep enough for dirt and crap to be swept out without embedding in the pads and later causing rotor grooving. But they are only cut down to minimum wear depth. When the rotor is worn out, the grooves are gone telling you the rotor needs to be changed.

Sam, how does the black coating hold up to road salt? My "winter beater" is a GMC Canyon 4x4, and the back sides of the OE rotors are showing some rust damage that's eating into the swept area. Therefore I'm looking to replace them, and thought the ATEs might be a good choice. What's your take on it?
Thanks!

so way is it that corvettes,porche,mercedes,etc have drilled rotors on ?
I have heard that drilled rotors stay cooler because of the holes and the air cooling from inside out.
I have had brembo sport rotors for 2 year and i autox , trackdays and no problems.

manufactures are PAID to put certain things on vehicles. why do you think firestone was used exclusively on ford trucks for years, despite their exploding tire issue a few years back? firestone PAID ford to put their tires on their truck. gets them advertising, plus when people need new tires, many of them will just say 'put whatever was on there before'.....hence getting firestone more business. just because it comes on a car stock DOESNT mean its the best of all options.
and again, many of the very high end cars now have carbon fiber rotors. comparing them to regular iron rotors are apples and oranges.
this has been beating to death and back. do a search and youll see there is no benefit whatsoever to drilled rotors. even on tireracks website, there is a disclaimer that drilled should never be used on track or high perf. applications, and are not warrantied against warping.....at all.
and remember this......PADS stop the car, not the rotors.

That picture of the rotors on a car with ROH wheels: That car is driven year round in PA, complete with Dunlop Graspic winter tires. The MetaCote doesn't seem to be phased by road salt.
I looked and ATE's are made for the Canyon. $94.00 each for the fronts.

I also run ATE rotors on the front with the Hawk HP+ pad and have been very happy. The rotors are great for the money and still look sharp with zero rust anywhere.

They don't run cooler, in fact the holes trip up the air flow through the vanes. Why do Corvettes come with one front rotor vaned backwards??????

a cup of cold **** will destroy your motor.
brembo sport rotor are made from carbon ceramic steel . they claim that the way the pattern is design is what helps with heat,gas,buildup and will prevent stress fractures due to high speed braking. if you compare the hole pattern from a brembo rotor to others you do see a diffrence.
just my op....i have always use brembo since racing AMA back in the late 80,s early 90,s

Really, anytime you take material away from the rotor you're hurting the structure. This allows temps to build faster (less material to absorb the heat) and less resistance to warping. I don't care care what they say, slotted/drilled rotors < non slotted/drilled for braking performance.
Looks are a different thing

Not to mention that saying all Brembo's are alike is as silly as thinking all Chevrolet's are alike. Yeah, an Aveo is the same as a ZR1... 
Frankly those Brembo Sports rotors are the same as their blank rotors, then they drill and/or slot them. Look up the part number, you'll see they are all the same but for the first number. Not like we're talking about some specifically engineered super duper fancy drilled rotor. It's a drilled blank. I can sell those too, but they are way overpriced which is why I don't.
