Got my first rotor today in the mail - heavy and huge, wow. Stamped L but I'll recheck fins orientation for sure.
ADD: fins orientation is wrong - stamped L but those point forward. Will install to RH.

Not to let this thread die prematurely - I'm still waiting for my fancy Powerstop pad sets. Supply chain issues to the max...
I even burnt thru one rear pad sensor while waiting (thought I'll cut it close but no, no dice) and had to replace it and temporarily install new rear pads (non oem, one of trusted local brands, 10 euro per set) to keep me driving... But I didn't swap rear rotors for new ones, so when I get the sets I'll install all round new rotors and all round new powerstop fancy pads.

Okay. Finally done this install.
Good thing I had a (only one tho) rep kit for my used 6pots. 4 boots on one side (and thankfully none on the other) had damage.
All pistons and cylinders immaculate tho.
Install was rather easy, I've replaced backing plates too (obviously, no half bakes here).
Assembling those are so weird and unusual, but cool.
Z23 powerstops gone in, bedding phase.
So far I can't pinpoint it clear enough to explain (I will) but there's a difference.
First off - I feel that both front wheels are heavier now. I mean I know LS pretty good and this is what I've felt straight away.
Braking force - can't judge yet, bedding in progress. But pedal feel is definitely different now.
Noise - none. At least yet. I've installed all new hardware too, pins, pin bolts, springs, guides.
I did do full double flush and bleed (till I bled), then reset mem, then setting all acc/dec/etc sensors on flat floor, then Linear Valve Cal. All good.
To be honest this install was planned for early spring, but circumstances surrounding progressive loss of brake hold (creeping more and more every day) prompted me to finally find a whole day and solve it (really annoying, I'm always brake holding when I'm not adaptive cruising). Oh yea, adaptive cruise in traffic went nuts too, coinciding with brake hold problem. But that's a whole another story. IDK should I post it in this thread or start new one? It was BAD.

Ok, month later and I can somewhat do a review.
In short - I love it! Thanks to everyone who recommended Z23 powerstops. They feel GREAT!
Overall brake feel is improved, stopping power too.
Great upgrade.
PS. Front axle did feel 'heavier' to steer and on non-ideal roads, but I got used to it in a week, not noticing it now.

Ouh-kay. These babies saved my butt today. Crazy t-bone in front, guy in the rear, 80mph. I was able to come to a controlled stop, even modulated brakes so guy behind got some warning and also stopped. Phew.
Worth every cent this upgrade!
Not the best of Mondays, rock did hit my screen... Did pro injection fix within 1hr, but not getting my hopes up...
Oh, and I was driving to pick up new hpfp (cos my bank 2 is noisy when cold, not cool).
Things we do for them, teh lurve...
When guy was injecting polymer, it was really bright in there and I noticed my grille peel just baaarely starting to lift up upper edge... And emblem isn't perfect any more.
Well... I'm going to order and put on that Sports-package grille. At least there's nowt to peel... And new emblem. 600usd (grille 350+emblem 250) going to be well spent over summer....

Is there really a big noticeable difference between the 4 and 6 piston calipers in real life ?

It's not big but it's noticeable. I've already got used to firmer pedal feel, so when trying 'regular' LS pedal now it feels lower and less positive.
