They are very different cars to drive on track in my experience. Try to drive a 4RS flat out on track in the same style as you would a 992GT3 and it falls apart in comparison.
You need to trail brake the GT3 to get it to turn in as you would wish( less in the 992 vs 991) but in complete contrast in the 4RS you get the braking done in a straight line and steer on the throttle otherwise you unload the back wheels too much.
I found that when I first drove my old 718GT4 on track I tended to over brake until the apex as I was so used to my 991.2RS which I learnt to drive on track in. This resulted in me over driving the GT4 and not really going as fast as I should have been. Same on exit when getting on the power. In my 4RS I think I've started to adapt my driving accordingly and getting faster by not driving it like a GT3.
There is also quite a difference between driving one 4RS with Mags and PCCBs/STs to another fitted with and standard alloys and Steel brakes. A total of 30KG less both unsprung and rotating weight makes a real difference in my view.
The 4RS and GT3/RS are different enought in the way they drive that a lot of it comes down to what platform you're used to, and equally personal preference. Not so much about which is better just different .
All in my extremely humble opinion of course.

Agree. This is the challenge when driving them back to back on a track. You have to try and make a deliberate adjustment in driving styles between sessions. If you forget, and drive the 4RS the same as the GT3, as you say, it falls apart. However, you can drive the GT3 in the same as the 4RS and it doesn't fall apart to the extent the 4RS does.

They didn't work that magic into their 'lesser' Cayman/Boxster platform, so it takes a real driver to get the most out of the mid engine Porsches.

Indeed, not long after PAG launched the 4RS, I was at Spa early April 2022 and Porsche had 5 of the first cars off the production line there for us to drive. We were one the first group of people to drive the car. The Journalists hadn't even driven it yet.

After my first stint, I commented to the engineer responsible for suspension development that the car felt loose in the rear end and needed more tyre both front and rear because could really feel the limitations at the heavy braking points around the track especially. He responded that the development team actually requested more tyre but that would have required changes to the suspension and bodywork for which there was no budget so they had to work with the current hardware. So, yeah, it missed out on having some magic applied in that area.

Wondering whether I really want / need that for my SRS.

Interesting. You are making me want to track my 4RS now. A call to TPC racing might be in order

When it's rotating, it will want to see keep rotating more, demanding quick reflexes, but it's the most rewarding feeling when you mastered the technique. Slight change of the throttle input is all that's need to change the trajectory, tiny change in weight shift makes a lot of difference, unlike in a 911 where it takes a lot of weight shift to move the needle.
