Thanks for your note... my belief is that slotted delivers the venting benefits without the hassles of cracking associated with cross-drilled... to each, their own... re Stillen engineering, they did everything they could to ensure ease of install, but they can't control how nissan designed the backing plate. And putting a custom backing plate would drive up price. All other aspects of the install were straightforward.

I don't think cross-drilled are for looks. I think that cold air inter the vent in between the disk,and hot air exits the disk throe the holes. and i also think it's good for wet weather. their lighter too.
cross-drilled also have their down side. they crack.
I don't really want to turn this into a debate. but i searched and found this nice write up Cross Drilled VS Slotted Rotors
If a respectable company like Stillen,and AP Racing work on a break kit. "exclusive for the 370z". Why did you have to do modification to correctly fit the break system? Or are they just off the shelf parts that they put together?
