My strut-suspended 240Z (with some camber and with from-the-factory rear toe-in fixed!) easily turned in better than my S2000! They had the same weight distribution at 49F/51R with driver and fuel. FT86 suffers because 55F/45R...

Been there, done that. As backwards as it sounds a lot of it was resolved by upping the front sway bar stiffness. It only happens on longer high load corners. In other corners my car is oversteer biased It has been driving me crazy. Yeah I can imagine that is the primary contributor physics being what it is and all. I should send a link of this guys in car to you cause it is nuts. The fastest twin I know of in the area has aero and 298whp and ran a 1:51.6, this NA S2K makes 210whp on race gas and has aero and ran a 1:49 on A052's and a 1:47.9 on A005's. The corner speeds are absurd

Did the front pack down mid corner?

Yes. Stiffer sway was a band aid. Going to mess with different spring rates next season, on 7kg now. Have another set of 10kg, so need to order 8's and 9's.

Being 500# lighter helps too.

Fer sher! But it's worth noting, the FT86 with driver and fuel puts 10% more load on its front wheels vs. an S2000 with driver+fuel at the same weight. That's significant and I think that's the bigger difference between FT86 and S2000 than front struts vs. double wishbones. That is, assuming the FT86 has crash bolts and/or offset top mounts or camber plates...
