OK OK...one more part this spring! I just ordered a set of Zip Corvette polyurethane shifter bushings. Nothing crazy or fancy, just like the shifter base bushings on DSM's and Evo's.

Of other interesting note, the C7 Z06 LT4 uses the same exhaust system as the Stingray/Z51 LT1 w/the dual-mode performance exhaust option. Right down to the same part numbers except the exhaust manifolds, which are cast stainless steel vs. cast iron (same design though). There goes any chance of the stock Z06 exhaust being an upgrade for the base and Z51 models. That tells you how well the exhaust system flows though. After the exhaust manifolds, the primary cat downpipes are 3.0", then the X-pipe transitions down to 2.75" after the secondary cats and continues through the axleback.
