I assume at least part of this post is aimed at me.
1. From the TireRack test at Streets of Willow where the BRZ picks up 2.5 seconds going to Bridgestone RE11A's from OEM, a BMW 328 picks up 0.7 seconds ditching the S001 runflats for a tire in the same category Yoko V105, going from that category it picks up another 1.7 seconds on Yoko AD08's a comparable tire to the RE11A/ZII, RS3 etc. I stand by my statement that the S001's are not a large advantage. Worth a couple tenths over the Primacy? Sure, not a whole second+, you'd pick up a similar amount of lap time upgrading the Miata's as tested rubber as you would the 86's, it'd bring them closer but not a magic bullet. Video source below.
2. LSD is a must, agreed, it's a shame it costs so much more to snag in the Miata.
3. It's not 20 unsprung lbs, it's 10 lbs total, that's 2.5 lbs per corner. Heat capacity is not utilized over one single flying lap and can be managed by a pro driver, OEM brakes would have performed almost identically over a single flying qualifying lap, I'd bet on it. That's how these tests are performed, the BRZ certainly didn't run a 1:51 on it's 5th lap out on stock brakes around Laguna Seca.
4. The Club absolutely comes with Bilsteins and I'd bet it makes a noticeable difference, full on board with you here as well.
