Any word on 2 pc rotors and lighter calipers?

Just curious really,

I know they offer fairly dramatic weight savings off the stockers.

For what type of use? I have the aerospace pro street 13" drilled and slotted rotors, with Billet 4 piston calipers. Saves a ton of weight. Not sure how they would hold up in a handling environment, but they're great for street and strip use.

Street-strip with some spirited back roads/twisty work.

Not sure if I would ever take the car out onto a Thunderhill/Willow Springs type course.

I also just emailed (Aerospace) about a 2015 set based on your thread. To a point I was hoping to strike a balance between the two realms of racing? Something that'll offer about 15-20lbs of savings while maintaining mild track work
