Notwithstanding looks.....
I'll repeat my Porsche Brake mantra on this forum again.......
Porsche have never or don't ever under engineer the brake systems on their cars...... In fact if anything they massively over engineer them so that they have enormous extra capacity but in terms of actual stopping power and thermal loading.
If for whatever reason your Lux brakes appear inadequate, its most likely a function of age related deterioration of the components rather than the set up is insufficient.
If you look at the various Race series of Porsches, unless I'm mistaken they all have to use Standard brakes for their individual models. They never have any problems stopping even with sticky competition tyres (inc. slicks) and uprated suspension parts.
So, my advice for what its worth replace all the wear and tear components on your brake system as a start:
Fluid
Flexible hoses
Pads
Discs
If necessary have all four calipers refurbed/ exchanged for new ones with tight seals and corroded pistons
If once you've done this you're still not happy then you can embark on a brake upgrade - bear in mind though that you'll also need a different Master cylinder due to the increased volume of the 4 pot calipers and potentially a different brake bias valve..................

I fully agree with that. On previous cars (unless the brakes were truly dire as a factory setup (read one car in my signature!)) simply braided lines, good fluid (ATE Super Bluw) along with fast road pads that work all of the time (Hawk pads, Mintex M11144s along with Ferodo DS2500s) have given me brakes that can stop on a sixpence, even in town traffic.
However, I ask again? Is there is a weight difference? On my daily, a reduction in the unsprung weight made for a massive difference in how the car drove (for the better).

I've never had the opportunity to weigh S2/turbo calipers nor Lux ones.
My instinct is that the alloy Brembo calipers wont actually weigh much more than the ATE sliding calipers.
However, the larger vented discs both front and rear will be substantially heavier = more steel !
Therefore, the S2/Turbo set up will be/ is heavier.

Believe the Wilwood kit is around $1000......
Would agree, probably not a lot of difference unsprung weight between the standard setups.
What wheels arecyou running - thats an easy place to lose weight.

I asked my question for one reason.
On my new found toy the Wilwoods are significantly lighter than the stock calipers. As a matter of fact I was quite surprised when I physically picked up a Wilwood Midlight caliper at the show; Wow they are light!
However, I did suspect that the calipers weighed a similar amount but it would have been great to have been given a quantifiable amount
.
Indeed it is.
In most cases you can make your stock brakes better with a few improvements.
As an example both my Pug 205 GTi 1.6 and 106 GTi had 247mm brakes. Granted the Pug had the smaller piston 'Bendix' Brakes with alloy carriers.
Out of the two the 205 braked far better to the point that I struggled to trouble it! I should admit here that it did had braided brake lines, ATE Super 4 brake fluid in addition to Mintex M1144s (despite what the naysayers say they were an improvement around town!) with OE discs. My 106 OTOH was truly attrocious; I needed to say a prayer anytime I wished to exert any brake pressure! The pedal feel was fine, but the braking itself was not! My RST is on smallish discs on Wilwoods ; that also is not too bad, but that is cheating.
However, in most cases, the stock brakes are fine with a few minor alterations if you are not massively concerned about looks.
