The wheel is the one you need the lightest. A set of 19" forgelines with Pirelli DHs saves 7-8 lbs per corner compared to the GT4 982 wheels.
Going with a set of Lightspeed or Augment Mag wheels in 19" would be the ticket coupled with the AP kit.
BTW...the AP setup will brake far better than the PCCBs...I will trade 1-3 lbs per corner for having bette rbraking.
Plus much easier pad changes.

AP brakes are top notch, no doubt there.
We'll have to wait and see how much a set of 19" magnesium wheels can save over the oem 20" magnesium ones.
This is what i will most likely end up doing....

But keep in mind...even with the Iron brakes you have a 408 mm disc and the big OEM caliper....will need to stay in 20" wheels.
IMO OEM Mags in 20" vs Lightspeed Mags in 19" at the most 2-3 lbs...but since you are doing customs wheels you can do a 9" front one which is on par with the GT3 and helps with handling.

How do Surface Transforms' brakes compare to AP, and do they have a kit for the GT4 RS?

Good question....the ST rotor will be lighter and contrary to PCCBs can be re-surface several times.
With ST you are still using the OEM caliper vs the much lighter AP caliper. So weight wise it kinds of balance out with a slight less weight for PCCB/ST.
Cost is around $14K for the 4 ST rotors and $13K for a full (F+R) AP kit including pads
I'm betting the 992 GT3 kit will fit the GT4RS but in any case AP/ST will almost sure develop the kits
In terms of braking I can't comment as I have never tracked a car with ST rotors...many PCCBs on the other hand.
I do like the choice of pads that Iron rotors provide and personally the pedal feel.
Disclaimer here....I'm looking at all of this from a track use perspective.

Tires stop cars - the RS has plenty of brake and in built cooling. It doesn’t need an aftermarket kit.

If you want 19" wheels you do need it.....

BTW...a friend showed me a pic of a GT4RS in Miami (on a building parking). He told me he know the owner so must be that VIPs are getting their cars already.

No one is getting their cars in the US yet. June builds for VIP’s.
