its not about having money in advertising or high prices. If they are made by the same brand that makes stoptech, it would be VERY smart for them to put that on the site. obviously i should be skeptical of a much cheaper rotor, that really is something that you shouldnt cheap out on. Since I am one who actually goes out and tests the products at their limit, I will pretty much be the judge on whether they are good or crap. I am willing to try them and if they are good then will retract previous statements... but you have to understand where I am coming from seeing a set of very cheap rotors that havent really been proven anywhere.
