Gnil:

Weight difference is not so big anymore as their size has increased. 

The new steel brakes on the 4RS are the same ones as on the 992 GT3. They are excellent. Bite is stronger then on 991 GT3 RS for example.

The metal ones are bigger now (408mm in front) and a little thicker too, so I would think there is some meaningful weight difference.  My steel rotors are wearing very well - no cracking and plenty of meat left (using gentle RE10 race pads).

When I added RE10 pads, I first scrubbed off all the old (stock) pad material with green 3M dish scrubbing pads and Simple Green cleaner.  Never any vibrations (mine is an early 2022 before any updates from factory).

If someone was set of PCCB's and couldn't get them, the Surface Transforms are highly rated and easily added.
