Tyr13, you made a real good job with this setup !
I also love that car and I thought I found THE setup to be quick
I have designed my one to chase the ultimate lap time. (I post it now for those who need to compare)
Comparing them, your setup is very close in performance potential to my one. I think the gap is more due to each one driving style more than real potential differences.

On Tsukuba , my best lap time was 0.51.505s (with R5). the gap was just 1.083 s between the 2 setups. I'm sure as you feel comfortable with your setup you can find that second (maybe not easily !) When using your, I know where and why I loose tenths but the way I drive can't make me avoid it

Just adjusting ASM understeering to 10 and TCS to 1 and gearbox with much wider ratios, the gap dropped to 0.035 s

I also hav to add that I have been unable to repeat my best time I made and comparing with, then my average perf would be very close and maybe worse than using your setup.
Meaning your setup is really a good one I suggest everyone who like muscle cars in general and especially Super Bee would use. For sure he will enjoy
Of course you have my vote
