Any cons to using the slotted, or cross drilled disc brake rotors? Do they really work as well as I hear, or is it all a bunch of hype? My '70 is going to need new rotors soon, thought I may use either slotted or drilled rotors and better pads. If they do work, what's better, drilled or slotted?------------------

You asked for the cons, and I believe drilled or slotted rotors wear down your pads quicker, which is logical if they're doing a better job. That's all I know, sorry

drilled rotors have a tendency to crack unless the cross drilling is done in the right pattern and the holes are chamfered. slotted rotors have no draw backs as far as i know. if the edges are sharp you can take a dremel grinder and knock off the edges, the will also reduce or eliminate any stress risers caused by the slot milling. if you have a choice, go with the slotted rotors over the drilled and solid types.

And you might want to ask what country they came from, and pass on any Chinese brake parts......
