I doubt any company would want to answer those questions, Chris lol Maybe high end company would want to. I'll give it a try and ask them

 

Please remember these are your brakes you're asking questions on.. lol.. there are several components on the car you drive everyday you might want to consider ensuring are good quality..

Can you build a set of cross drilled or slotted rotors for $60? Of course you can.. but who knows where they are from, who knows where the discs are manufactured, who knows what they are made of and of what quality, even excluding the refined process of drilling them..

It's not a shift ****.. ask questions.. please..

 

$60 does seem like cheap to have slotted and drilled. i have centric blank for $100 on the front and no issue. I sent them the question and let's wait till i get answers
