Welcome to Corvette Action Center.
I don't have an answer for tire/shock combos, but I think you should consider what the intended use of this vehicle will be, before you decide on a combo.
Various uses will require different combinations...like the differences between slalom course racing, drag racing and stock street driven on weekends.
If you don't plan on using the vehicle hard, I'd stick with close to stock, but you need to be happy with it, so decide what will make you happiest.
