I also switched to Centerforce's new twin disc clutch.. now typically I'm against these since they are more of a PITA than helpfull, but we installed this on our 2010 Camara and it was both stupid easy to install and felt like a stock clutch in the car with zero rattles or issues.
The flywheel is steel but the edge has been lightened and from a MOI standpoint is equal to an aluminum unit without the associated problems. Should hold up better to the power and to how I drive.
