like i said, your knowledge of performance brakes is very limited. they are purely for looks on stock cars because people want the looks. one of the corvette engineers straight told me that.
i'm not talking about cracking with street driving i'm talking track driving. doesn't matter what brand, drilled, cast, dimpled or even solid rotors they will all crack. the slotted or drilled rotors will crack before the solid rotors will every time because they are stress risers.
