Base vs S - weight

[Boxx]

Looking thru ads there are alot more bases than Ss, probably 3 to 1.
I want an S, and from reading forums, that's what most Boxsterers prefer too.
For me it comes from driving a light, fun, tossable, but underpowered sports car
for years on end. I lived the 'slow car fast' mantra for over a decade, and I liked it.
But I've already played that song this set. I don't need a redux.

So I'm pretty set on an S from my personal history.
The question is, why so many base models, beside price of course?

What is the weight difference? I'm guessing less than 100 lbs.
Bigger rotors, heavier crank and connecting rods,
beefier drivetrain and suspension components. How much total?

Can you feel the weight?
Is the base model just marginally more light on its feet?
Is the power difference bigger than the weight loss?

And the engine - is it smoother? Does it rev higher?

What are the Bore/Stroke differences? Is the S just a longer stroke -
since you can't really bore it I'm guessing it's a stroke-only change
as that would be more cost-efficient than manufacturing two blocks.

I've read enough posts to see that most prefer the extra torque, as would I,
so I'm asking about handling and engine smoothness.

And any other differences you might notice, like is it louder?,
as you are always revving higher to get the power you want?


That's: weight, power, handling, bore/stroke, smoothness, decibels, anything else ...

Thanks.
