I have no idea if stance or buddy clubs are better.Good luck with your set-up.
BTW, almost every one I race with uses a Koni shock most of them use Yellows, some re-valved, some not. But almost no seriously competitive driver that I know runs JDM Coilovers (there are a few exceptions). Most run koni or /Bilstein/moton/ohlins/penski.
I still don't understand why you think a Spring shock combo is inferior to a "coilover". And with adjustable spring perches, I can't fathom what the difference is. You never did answer that question. I guess my threaded spring perch, shorted top hats, shortened & revalved shocks and 700/450lb springs aren't as good as a "coilover". All I can say is good luck, happy motoring, and be safe.
What ever, I'm out.
