Comment #1: I've seen various 'official' numbers floating around, some numbers say 0-60 in 4.8sec and some say 0-100kph in 5.3sec, it certainly does not take half a second to get the extra 2mph, so one tends to think different pieces of the organization are pitching different numbers for differing reasons.
Comment #2: I'm not sure what the difference in wheel weight is between the OEMs and the Schnitzers, I can't imagine the OEM wheels being crappy-Neeper-aftermarket heavy.
But yes, reducing the rotating mass can result in considerably more torque getting to the road, I've seen dyno tests where a 15lb reduction in wheel/tire weight resulted in a 20HP increase in dyno-measured HP.
