One thing that may be helping @berns crush it is his LSD, helicals are pretty suboptimal for heat, high power cars like ours and I think he's running a custom clutch plate diff if I'm not mistaken.
FYI - checked times and my time was a 2:01.01 Sunday at Buttonwillow.

Rear suspension arms are stock, and my car isn't that low. Is something bent on your car? I was able to hit -3 camber out back when I played around the rear adjustment. However, I didn't try to set the toe at that -3 mark, so unsure if the factory arms have enough adjustment at that point. At -2 I had tons of toe adjustment to get things wherever I wanted them.
Disagree on the diff. It's a helical gear, it doesn't care about temperatures, it's not like a viscous-coupling diff. It's not as tight on lock-up as a clutch-type diff, but miles ahead of the stock e-diff. I had no problems leaving two deep, black rubbery lines around a few corners to celebrate after my 1:52 lap at Autoclub.
We're all at right around the 2:00 mark around Buttonwillow with similar setups. The race is on the to see who sub-2's first.
