The rotors- you DO NOT want drilled. They will crack.
I ordered the Centric slotted front and rear rotors.
Centric calipers-have the steel pistons.
I went through PartsGeek.com
FYI - Parts Geek doesn't specify piston type for the Centric pistons. Looking on the Centric parts page for the E-450 directly (http://centriccatalog.com/Inquiry/AppResult.aspx?id=WEB_CALPIS&v=MD/HD&y=2004&m=54&mm=2467) - it indicates that pistons are Phenolic if buying pistons alone....
A1Cardone sells calipers with metal or Phenolic pistons via parts geek...
