I thought I saw on an earlier post that you recently acquired your Corvette. I think I know what you are going through mentally. What can I do to make it faster, better looking, better handling, supercharger, bigger throttle body, revamped ECU, chips, headers etc, etc. Just a unsolicited suggestion; I would get your car in excellent mechanical condition first. Change all fluids as necessary, tune up, new wires and so on.
Then get to know what your car is capable of doing as it sits. Corvettes are VERY capable cars from the factory. One mod by itself may actually do more harm than good. Good mods come in groups, i.e. cam, roller rockers, throttle body, long tube headers and so on. Take a few weeks to read all the posts on this boards and then do a budget to see what will give you the "most bang for the buck"
17" wheels (ebay) and performance tires will improve your handling, as will new shocks, bushings etc. Plus they will look great on your car.
I'm not trying to preach, or tell you some you already know. But I've been there, done that.
Good luck and Keep the Wave
