You can get the 1LE "track pack" parts from dealer has everything but wheels and transmission i think. There is also aftermarket available like pedders that are much better. 3.91 gears are available for autos. Recaros are available as a dealer option or aftermarket. Heck you can even get the 1le/zl1 wheels from dealer but for the price go aftermarket for better looks, performance and cheaper. Lastly NPP can be ordered and cost as much as any top of the line aftermarket catback...
Happy wife happy life
Also to point out your assumption that the lambo and Ferrari are auto thats false they are dual clutch...atleast have been for a while...like gtr. A tune crisps the auto trans up quite nicely.
