Without going into to too much detail that could be trade infringing, the carbon content is pretty much the same as the premium rotor but not exactly. Now the standard rotor is a car lot special. I run Centric premiums on pretty much everything. The reason they make the line is because of internet forums and message boards, same with the cryo. Enough to be legally different. Someone came out with a buzzword, it made some money, so now they make it to satisfy the public desires. One of those things "It's more expensive, so it has to be better", ya know?

+1 on the transfer layers, I have used many a 3M cookie and re bedding to fix a "warpage" issue. Another thing that will get you is the ecoat of some of these special rotors, it will completely wreck a set of pads.

I was just recently given some pads from tier1 supplier to try out on my Ex and report back to them. Once the results are in I'll bring that back to the forums.

A lot of the "drilled" rotors are just that, just drilled on a jig and then machined. More expensive manufacturers actually cast the holes into the raw casting and then are machined and chamfered to resist the cracking. Of course those rotors usually will run you in excess of 200 a piece, are American or even European made and will not be sold by tire rack, rock auto, amazon, fleabay.

 

My trailer brakes are good, and the brake controller works well. I've tested it thoroughly. The climb up/down to Death Valley is beyond nasty. 5,000 feet up and down twice, full of nothing but tight switchbacks. It's the worst road I've ever had he pleasure of driving. And I'm no novice.

The stock brakes did well, but the 1 rotor has now warped. If I'm gonna replace it, I'll replace it with a good upgrade.

 

Guys, I run a set of the drilled slotted ebc including yellow stuff front an rear since 13months
Ive done a complete set of Ssbraided lines, too.
Its an extreme increase of brake power....believe me and the dust is way less than OEM.
Im located in Germany and I drive this tank hard and sometimes aggressive, which means hard brakings. I drove 6500mls and you cant even feel a groove in the front rotors. Awesome pads and awesone rotors......
You cant be wrong if you get not copied china stuff.

Drilled and slotted rotors actually remove material from what is essentially a heat sink. You want as much material as possible so it can absorb as much heat as possible before causing pad fade. The slots and holes for race cars are not appropriate for street cars outside static displays at car shows.
