Welcome and congrats. RCF hides its speed very well especially as its power delivery in a different manner with its long gearing/high rev limit. Have you tried all of the most aggressive settings? Personally, in lead/follow in my RCF with full exhaust holding its own with several FBO/modded ISFs in a F meet in July.
In normal modes, everything is dialed back. It feels sedate. Once you put it in sport+ and manual mode (and TVD in slalom or track mode) and rev the car up to redline, everything tightens up especially at higher revs where the steering and shifts are at most aggressive. Also, RCF is severly restricted by its exhaust. It really changed the car once I got my Invidia full exhaust.
The RCF and ISF are obviously similar in performance, but get there a little differently. The ISF feels quicker because it's lighter and the RCF masks its speed a little more. I also had an ISF with the Joe Z exhaust and thought it felt and sounded great. The RCF is a nice step forward in tech and feel, but it isn't appreciably faster.
The second I saw that Molten RCF I knew Rolla would be the very first to reply to you VDODSON!!
Puzzled why they discontinued the ISF, but then again I'm puzzled by the end of the GS as well. Meanwhile back at the RCF Forum........
TVD? I have not even read the manual yet. Will be pouring through it this weekend.

Sorry, my bad. It is only for the RCF with the carbon fiber/torque vectoring differential (TVD) package. It was meant to be a comment about the most aggressive settings for spirited driving/turning capability. You can certainly ask questions about settings, configurations etc. on this forum.
Your RCF does not have the TVD. It's part of the Performance Package. But you do have a Torsen LSD.

He might have one of those unicorn early 2015 RCFs that had TVD as a stand-alone when the carbon fiber manufacturing was stopped due issues. It is a button in the center console so it is worth checking.

I think the IS F, RC F, and GS F all have the same gearing (long), but the RC F and GS F have 500 more rpm at redline so they hold the gear for 500rpm longer before the shifts. So an IS F at WOT will shift from 2nd into 3rd ~66mph (6,800rpm) while an RC F/GS F will do the same shift ~73mph (7,300rpm). So it may feel a bit longer in gears. Of course, the IS F is also lighter. Yet the newer Fs have more HP and TQ. They're really close in the end.

It becomes longer because of the bigger wheel circumference as well. Pre-2020 RCF has the same gearing has the ISF, but the high-rev and the much bigger wheel circumference all make the car's engine poiwer delivery more top end focused.. I am actually looking into putting 285/30/19 to shorten the overall gearing.
Edit: I have seen video you posted many years ago when this topic was beaten to death.
