damn...long thread. if 2011 gt buyers that plan to race the car are smart, they'll stick with 3.55 gearing. The 3.73's (and a 27'' tire iirc) force a shift to fifth gear before you hit the 1320, causing a slight hit to ET and trap...likely why this one had a 109 trap instead of the usual 111-113 we're seeing from the 3.31 and 3.55 geared cars.
