1) Push button underdrive module with PLC and actuators (logic: push on it waits 15 seconds for active handling "comp mode or off" to be engaged, if not it goes back to normal gear).
The underdrive setup (3.90 total for 58mph in first 130mph in fourth) option for track slicks (stiff sidewalls) would be nice! Soft sidewalls might bust things up to much for a warranted car (twisted out rear end could and already probably would void warranty!)
Street to Track in a hour!!!

Practically!
1a) A GM T-Spec:
Interchangable larger front and rear spoilers.
Camber, toe, ride height, DOT slicks, gear.
Button switchable active handling algorithms and programming. Maybe!
(0-60 in 3s and quarter miles in 10.9s or less (paddle shifters 10.5s); the ring in the teens, 7.10s?)
2) Push button overdrive (logic: waits 15 seconds for cruise control to be engaged, if not it goes back to normal gear).
The six gear already works like it has a 3.90 rear end. IT COULD USE AN OVERDRIVE(about 2.70 or more total it has the torque for lower rpm cruizing), while there at it in the same pre-transmission bolt-on gear box (maybe shorten the torque tube and the drive shaft for the module?).
The top of 6th would be around 190 (the ring he never went over 176) so all the power would effectively be on tap for the ring, 1/4's, and 0-60s. Of course the engine would be working at higher revs too, could she take it? Could we?

And then we can take over the world!
