Power to weight is what propells all sports machines into peoples dreams,
But, the fact is your S2K is not a Lotus.
To get that sort of power to weight with no improvement in power,
You're going to need a lot more than $10K.
Carbon doors, carbon roof, hood etc...
& still you'd struggle to get under the ton...
Doing all that, & leaving it stock? LOL... Ok...
As for minor power increase,
This again is a perspective thing.
