The extra joints of the IRS system are gonna add resistance...I know from our older Corvette stuff that geometry is super critical an IRS setup. A minute amount of drag/friction doesn't sound like much in a daily driver setup, but I know in our race stuff we've picked up just by paying attention to brake/bearing drag, axle/housing runout, etc. I'm sure the drivetrain engineers @ the Big 3 could tell you in a second which setup is more efficient...and for my own curiosity, from a simple static weight standpoint, I wonder which setup would come out on top? Anyone have any poundage numbers on the 5th gen IRS setup vs. say a 4th gen solid axle, or even 12 bolt replacement?
